Question

Parthenocarpic tomato fruits can be produced by-

Answer 1

In some plant species, parthenocarpic (seedless) fruits may be produced naturally or they may be induced by treatment of the unpollinated flowers with auxin e.g. Parthenocarpic tomato fruits can be produced by treating the plants with low concentration of gibberellic acid .....

Answer 2

Parthenocarpic fruit development is a very attractive trait for growers and consumers. In tomato, three main sources of facultative parthenocarpy, pat, pat-2, pat-3/pat-4, are known to have potential applications in agriculture. The parthenocarpic fruit development in these lines is triggered by a deregulation of the hormonal balance in some specific tissues. Auxins and gibberellins are considered as the key elements in parthenocarpic fruit development of those lines. An increased level of these hormones in the ovary can substitute for pollination and trigger fruit development. This has opened up genetic engineering approaches for parthenocarpy that have given promising results, both in quality and quantity of seedless fruit production.
