Gibberellic acid biosynthesis during dehydration phase of priming increases seed vigour of tomato

Priming of seed is intended to reduce the time germination through activation pre-germinative processes. Seed priming controlled hydration followed by a drying (dehydration) process. The physiological processes during (imbibition) were studied in detail tomato. In contrast, gibberellic acid changes dehydration phase not detail. We hypothesize that there would be change GA concentration process, which may influence vigour characteristics resultant seedling. objective study was understand on biosynthesis and its subsequent effect seedling traits First, hydroprimed unprimed seeds re-imbibed for 3 h, 6 9 12 h initiate associated parameters recorded. second experiment, imbibed dehydrated then traits. Results revealed had higher than seeds. are completely highest parameters. Therefore, increased due levels accumulated priming, can improve
