Abstract

Considerable variation for different metric and non-metric characters was observed in seedling population of Pistachionut. The variation for non-metric characters was observed for precocity in flowering, colour of the kernel, shelling and splitting percentage. The studies have resulted in the identification of two pistillate and three staminate trees with desirable traits which can be exploited in breeding programme or used as elite planting material.

It’s because it impacts the active development of the plant at a low temperature. Yellowing of the leaves and severe destruction of the tissue. In cases of flowering plants, the stalk carrying the bunches freely lengthens and drapes down the complete inflorescence.

Abstract

In order to solve the problems of irregular bearing, lower yields and less colour development in apple, plants of different improved spur types and standard cultivars of delicious and other cultivars on EMLA 111 rootstock were imported from USA. Plants of different cultivars namely, Real Mecoy Red Delicious, Red Chief, Oregon Spur II, Criterion and Mutsu on EMLA 111 rootstock were planted at a distance of 15’x12’ with a density of 598 plants per hectare, in RBD design with 6 replications during 1989-90 at progeny cum demonstration orchard (PCDO) Anu (Jubbal). The observations were recorded during 1999-2002.

Clove bean is christened so because of the resemblance of its thickened pedicel to the cloves of spice grown in isolated pockets of Kerala. This crop is neglected so long and remained unexploited though it has good potential for development. The tender and swollen pedicel of the fruit is used as a delicious vegetable vernacularly known as michi in Hindi and Bengali, garyo in Gujarati, kattuthali in Tamil, gariya in Marathi and nithya vazhuthana in Malayalam.

This vegetable grows from sea level as in Western Coasts of Kerala to an altitude of 1700 m amol in the Himalayas (Kirthikar and Basu 1935). The crop grows in the Gangetic plains and in Deccan hills. It is distributed in warmer parts of South and South East Asia including Upper Myanmar, Nepal, Sri Lanka, China and Japan. (Raizada and Saxena 1978).

This is primarily a physiological condition and, after heavy rains or heavy irrigation during hot weather, is mostly due to high atmospheric humidity. Two forms of splitting have been found, namely radial and transverse. There is more frequent radial cracking than transverse cracking. While splitting down to the inner core is very unusual, partial splitting is more prevalent.

Microgreens are tiny seedlings of some wild species as well as edible herbs, cereals, and vegetables. They are developed from the seeds of vegetables, legumes, herbs, and cereals and are regarded as immature greens (requiring light for photosynthesis and growing medium). They are picked shortly after the single set of true leaves has emerged from the cotyledon leaves. According to Xiao et al. (2012), microgreens have 4-6 times the nutritional density of their mature counterparts.

Jaggery: Raw brown / unrefined brown sugar in lump made from palm sap (Plate 142).

Jam: A preserved product prepared on boiling pectin contained in fruit pulp with required amount of sugar, water and acid to a reasonably thick consistency, firm enough to hold the fruit tissues in position (Plate 143).

Importance of Light in Microgreens Growth

Microgreens depend heavily on light for their growth and development. Microgreens, being photosynthetic organisms, are very dependent on light for the process of photosynthesis, which produces energy. Sufficient exposure to light is necessary for the production of chlorophyll, for vigorous leaf growth, and for the accumulation of beneficial chemicals such carotenoids and phenolics (Mocanu et al., 2021). Research by Demotes-Mainard et al. (2016) and Kopsell et al. (2005) highlights the direct relationship between microgreens' phytochemical composition and light quality, showing how changes in light spectrum affect it.

Kalamata / calamata: It is brine cured black olive grown in Greece.

Kamucha: Tea cider or fermented tea beverages is known as kamucha.The fermentation process take place by the presence of yeast and bacteria

Kanji: Clean, black coloured, crisp and sound product of characteristic flavor prepared by full fermentation (chiefly lactic acid fermentation) of black carrot with 2.5% salt, 1% powder mustard and some amount of water. It is fermented to make ready to serve drink which is known as Kanji. Each kilogram of the grated carrots yield just 7-8 litres of kanji.

Karl Fischer Titration: Karl Fischer Titration is used for estimation of moisture content of foods (low moisture products).

ABSTRACT

Dissected shoot tips from healthy suckers of banana var. Meitei Hei (local variety) were inoculated on Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of plant growth regulators viz., NAA and BAP. After 15 days of incubation 50% of the shoot tips turned green in the medium with 5.0 mgl^-1 BAP. A maximum of 85.7% of the explants produced phenolic exudates in MS + 5.0 mgl^-1 BAP. After one month the explants were subcultured in fresh medium with the respective concentrations and combinations of plant growth regulators. After 75 days of incubation an average of 2.20 microshoots were induced in 78.57% of the explants in MS + 5.0 mgl^-1 BAP. The regeneration of shoots, leaves and roots was more proportionate in MS + 0.1 mgl^-l NAA + 0.5 mgl^-1 BAP. Under the treatment the microshoots had an average height of 1.19 cm with 4.13 leaves and 2.40 roots. The multiple microshoots were separated and subcultured on MS + 0.1 mgl^-l NAA + 0.5 mgl^-1 BAP for proper development. After 120 days the completely regenerated plantlets were hardened under green house environment.

Purpose of Growing Microgreens in Space Farming

Microgreens are a perfect dietary ingredient in space because of their special benefits, which have been explained in earlier chapters. In an atmosphere of a spaceship with limited water and electrical power for artificial illumination, their comparatively low light and water consumption are advantageous. Furthermore, because spaceships and shelters have limited capacity, microgreens' tiny size might be advantageous. Given the right sanitization procedures, microgreens may be harvested fresh and consumed right away. Their striking colour and robust flavour may also improve meal presentation and pique astronauts' appetites. 

Abstract

In the hybridization programme, the horticulturally desirable female line HC-17- 11(susceptible) was crossed with powdery mildew resistant male line FC-1.  Over the years, the variety CHP-2 proved its stable resistance (average disease score 1.58 on 1-5 scale) to powdery mildew under natural epiphytotic conditions as well as supremacy in yield performance (11.7-28.0 t/ ha) over the check variety (10.3-16.5 t/ha) in different testing centers of AICRP(Vegetable Crops) and farmers’ fields (20-26 t/ha).Additionally, the pods are medium long (9.25 cm),light green,7-8 seeded with 48-52 per cent recovery of light green, sweet and tasteful  shelled peas. The shelled peas contain 1.4 per cent soluble protein and 9.5 mg ascorbic acid/100g of fresh shelled peas.

Seedlings of several vegetables are first raised in well prepared nursery beds, followed by transplanting in the field. Raising of seedling in the nursery beds is economical as well as easier to take care of young, tender seedlings against pest and diseases. Further, raising of seedlings in nursery allow more time for land preparation.

Site and soil for nursery

In selecting a site for nursery beds, following points should be considered viz sunny situation, good drainage and irrigation facilities. Sandy loam soil with plenty of organic matter are ideal for starting nursery beds. In case of heavy soils it is desirable to add coarse sand to modify the soil condition. Before sowing seed it is essential to sterlize the beds by steam or formaldehyde or any other chemical to do away with problem of damping-off disease. Burning of leaves or straw in the beds is quite helpful in controlling certain soil borne diseases and pests.

ABSTRACT

Direct shoot organogenesis from several explant types excised from in vitro grown plants of local elite tomato cv. PKM1 was studied in response to zeatin, BAP, IAA and NAA. Cotyledonary leaves were found to be the most responsive explants. High shoot bud induction rate (>25 shoot buds/cotyledonary explant) was obtained in the presence of 2 mg/l zeatin. The organogenic calli were subcultured onto the same shoot bud induction medium for shoot development. Among different growth regulators tested, zeatin @ 2 mg/ l induced more number of shoots per explant compared to BAP, IAA and NAA combinations. Rooting was efficiently induced on half strength MS basal medium supplemented with 0.5 mg/l IAA. The effects of various growth hormones on tomato regeneration on rooting were discussed.

Fruit cracking is a serious problem of pomegranate (Punica granatum L.) particularly in arid climate. Cracked fruits are sweet but unfit for long distance transportation. Incidence of cracked fruits varies from 10 to 70 % depending upon the prevailing environmental conditions. Longitudinal or radial splitting of rind surface occurs.

Abstract

Plum breeding work has been in progress since 1991-92 and continued upto 1996- 97.  The hybrid seedlings thus obtained after one year of growth in nursery were planted in test rows for the selection of types that had improved quality and better shelf life. Cultivar Santa Rosa, the mainstay of plum industry in Himachal Pradesh though performing well from production and adaptation point of view but lacked in uniform fruit ripening, very acidic at seed and low shelf life or transportation ability. After detailed evaluation and characterization for various pomological traits, two-way hybridization in seven different cultivars belonging to Japanese and European plum were made. In test rows the hybrid seedlings were assessed for number of horticultural characters i.e. morphological, flower and fruit. On the basis of detailed analysis some promising types have been selected which are briefly described, however yield potential is being evaluated as most of  the seedling have started fruiting regularly only two to three years back.

ABSTRACT

In vitro culture induced genetic variation constitutes an important source of variability for the improvement in ginger (Zingiber officinale Rosc.). Hence attempts were made to standardize indirect method of in vitro plantlet regeneration in ginger using various explants like sprouted bud, shoot tip, leaf and pseudo stem. Explants from two cultivars of ginger viz. Maran and Rio-de-janeiro were cultured in Murashige and Skoog (MS) medium supplemented with various levels of 2,4-D and in combination with different levels of BA. Cultures were incubated under two different culture conditions viz. light and dark. Callusing was observed in all the explants except mature leaf in MS medium supplemented with 2,4- D alone (1 - 2 mg l^-1) and in combination with BAP (0.5 - 3.0 mg l^-1). Shoot morphogenesis was achieved from one month old calli in MS medium supplemented with BAP (3.0 mg l^-1). Regenerated shoots were subcultured to medium of same composition for further shoot proliferation and rooting. Plantlets produced were hardened and planted out. From the present investigation, highly efficient protocol for indirect organogenesis in ginger could be developed and the response of two cultivars at various stages of morphogenesis could be studied in detail.

Hedge

When shrub is planted on boundary for fencing, it is also called as hedge. In other word shrubs or trees planted at regular intervals to form a continuous screen is called a hedge. It may be ornamental or protective or both. Hedge also become an important feature of formal layout to serve various function as screening of the area out building, tennis court, vegetable garden, hardening of unwanted place etc. All the shrubs cannot be planted for making an ideal hedge due to different nature of growth.

Garden Walls : A garden lover will never like to block the view of his garden by putting a wall along its periphery. A garden as it is enjoyed from inside should also be visible from outside.

• Low brick or concrete or stone wall of say 60-90 cm height and to put over it some grills.
• Alternatively walls from 1.8-5.0 m may also be erected depending upon the size of garden.
• One may grow creepers such as Ficus repens over the wall.

Flower Beds: The most essential criterion of a flower beds is display the flowers in the best way possible. It may be born in mind that flowers look best when massed in a bed. The flower beds are of special importance under condition of the plains of India since they can be kept planted throughout the year unlike those in England or other parts of Europe where nothing can be grown in the open between November-March. Annuals and herbaceous, perennial flowers, flowering plants are grown in flower beds to provide massing effect of different colours borders is continuous beds of more length than width containing plant of one kind only.

An anomaly characterized by numerous leaves, short petioles and small laminae that offer a bushy appearance known as bushiness to some gerbera cultivars. The nodes are not clearly differentiated and no elongation of the internode is seen.
