Cotton Seed Priming with Brassinosteroid Promotes Germination and Seedling Growth

Cotton (Gossypium hirsutum) is the largest fibre crop globally and an important oilseed crop. Rising temperatures declining water supplies, which are also impacting soil salinity, threaten cotton plant productivity. Germination, emergence young seedling stages in highly sensitive to salinity heat stresses. Brassinosteroids (BRs) steroid hormones that essential for proper growth development promote tolerance a range of environmental seeds were primed with BR (24-epibrassinolide) alone or combination other (abscisic acid, auxin gibberellic acid) tested germination early growth. promoted under no stress as well conditions, while ineffective conditions. cotyledon opening lateral roots germinated seedlings. The ability positively impact across different conditions suggests priming may help successful establishment seedlings, benefit through its lifecycle.
