Could the umbel order selection and GA3 treatment improve seed germination in Amazon chicory species?

This study aimed to estimate the production of seeds per umbel and assess both effect gibberellic acid (GA3) order on seed germination in Amazon chicory species. The experiment was conducted two steps. Firstly, traits related were evaluated. Afterward, a test carried out, following parameters assessed: speed index (GSI), average time (AGT), percentage (%G), abnormal seedlings (%AS), non-germinated (%NGS). Remarkably, there strong interaction between analysed factors. highest plant observed treatment containing blend from different umbels (1.41 g·plant-1), which number by total major improved yield. application GA3 at 200 mg·dm-3 increased %G second-order seeds. Regardless application, secondary showed shorter AGT up days, while no difference GSI observed. Collectively, these results offer novel timely information behavior chicory, revealing practical advice utmost importance for local producers.
