Introduction

Aonla or Indian gooseberry (Emblica officinalis Gaertn. Syn. Phyllanthus emblica) is one of the important indigenous fruits of the Indian subcontinent. Most of the xerophytes are members of the Euphorbiaceae.

The tropics are evergreen, while the subtropics are deciduous. The highest concentration of vitamin C in aonla is found in mature fruit rather than immature fruit. The special attribute is its capacity to retain vitamin C even in a dried stage, which is not possible in other fruits.

Aonla contains six seeds per fruit, and in it is found zygotic dormancy. Flowers are borne in the axils of the leaves on determinate shoots.

Fruit crops are mostly composite plants consisting of scion and rootstock, except banana, papaya, and strawberry. Rootstock exhibits a great influence on the performance of a scion in terms of production efficiency, yields, quality, adoptability, and resistance against biotic and abiotic stresses. The primary function of a rootstock is to provide anchorage or support to the scion by growing deep into the soil and also regulating the uptake of moisture and nutrients. The rootstock cannot be changed during the life-time of a plant, so it makes it inevitable to pay more focused attention to it because its functions are long-term and complex.

Maturity (commercial or horticultural): Refers to the stage at which the produce is optimally accepted to the consumer.

Maturity index: The maturity at harvest determines the quality and postharvest shelf-life of the fresh fruits. The study of maturity indices helps to harvest the crop at right time.

Judging maturity: There are various means of judging maturity but they vary according to the kind of fruits, local soil and climatic conditions, but generally farmers follow visual means (appearance). But this is not a perfect method, many a times it may mislead the farmers.
