28-homobrassinolide Induced Changes Favoured Germinability of Wheat Grains

The surface sterilized grains of Triticum aestivum (L.) cv. HD2204 were soaked in graded concentration (10–10, 10–8 or 10–6) of 28-homobrassinolide (HBR), for 8 h. These pre-treated grains were transferred to sterilized petriplates, lined with filter paper moistened with double distilled water in a B.O.D. incubator, fixed at 25°C. The samples were removed 12, 18 and 24 h of their initial soaking. The treatment significantly increased the values for α-amylase, catalase, peroxidase, soluble sugars and proteins and percent germination. Out of the three concentrations, 10–10 and 10–8M proved best whose effects were comparable with each other, in most of the cases.
