DOES BORON HELPS IN SEED GERMINATION?

0

Based on an experiment conducted on Soyabean seeds, it was found that: >> Seeds with a low concentration of B have permanently damaged seed embryos, preventing their germination or producing defective seedlings. >> At slightly higher concentrations, embryos are not permanently damaged, but require a higher level of external B for their normal development than do those with higher concentrations of seed B. It’s found that Soybean seeds with B concentrations ≤ 10 mg B kg-1 have been reported to have deformed cotyledons. Seed with 7 mg B kg-1 performed poorly, with 80% failing to germinate. Hence, the critical concentration of B in soybean seed for permanent damage was between 7 and 10 mg B kg-1, and for normal seedling development in low B soils was between 14 and 20.
