Brassinosteroid used in least concentration plants growth were better than high concentration root. Germination of wheat HD-2204 varity, by used 28-homobrassinolide the concentration is 10-10M , 10-8M As a result, the germination of wheat. and Results of the 24-Epibrassinolide concentration at 1 - 500 nM were affected to increase quantity of Fe and chlorophyll increase in rice leaves. Brassinosteroid In duced seed morphological of wild rice (Taichung 65) and mutations rice (d61-7) varieties. Seed length and width were significant , byt seed thickness not significant and Brassinosteroids used concentration of 1 μM in 48 hours in barley can increased to primary root lengths
