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.
单性结实果实发育对种植者和消费者来说是一个非常有吸引力的特性。在番茄中，已知三种主要的兼性单性结实来源，即pat、pat - 2、pat - 3/pat - 4，在农业中具有潜在应用价值。这些品系中的单性结实果实发育是由某些特定组织中激素平衡的失调引发的。生长素和赤霉素被认为是这些品系单性结实果实发育的关键要素。子房内这些激素水平的升高可以替代授粉并触发果实发育。这为单性结实开辟了基因工程方法，在无籽果实生产的质量和数量方面都取得了令人鼓舞的成果。
