How much time is required from germination of pollen grain on stigma to fertilization in Solanaceous crops (chilli, tomato, brinjal)?
See the research below, I hope it will be useful to you:

The course of pollination was different in particular types of eggplant fl owers.
For solanaceous crops
For pollination-within Hour
Fertilization- 12 Hrs-18 hrs.
(Plants can transfer pollen through self-pollination; however, the preferred method is cross-pollination, which maintains genetic diversity)
In eggplant, fertilization is completed within 3 days after pollination and gene expression 3 days after anthesis is induced by stimuli of both pollen tube elongation and fertilization. Ovaries of unpollinated flowers began to senesce 3 days after anthesis, although half of them had the potential to set fruit.
In hot humid climate, cross-pollination may occur up to 20%, mainly due to heterostyly, even though it is treated as a self-pollinated crop estimated the amount of cross pollination in eggplant at between 0 and 46%, but cross pollination at distances of 50 m or more was nonexistent. The fl ower remains open for 2-5 days without closing at night.
