Encountering Sudan grass Stress Biology by Chemical Manipulation.
Execution of growth retardant by final step inhibition in GA biosynthesis pathway is not only a biochemical foot print of Daminozide but its simultaneous encouragement to other metabolic pathways are very nicely acknowledged by Sudan grass particularly in the stress condition. Sudan grass, Sorghum sudanense (Piper) Stapf cv. GK 908, a Poacean fodder grass experienced high temperature, encompassing with water deficit in acid laterite soil and low humidity in the summer days of Paschim Medinipur (West Midnapore) district in West Bengal, India where it was cultivated to study the crop improvement in terms of high biomass yield to feed cattle of that area. In this regard Daminozide 250mgL-1 and 500mgL-1 and GA50mgL-1 and 100mgL-1 in water solution were used as foliar spray on the field crop beside the control set to thrive the best result. Various morphological and biochemical changes were compared between the treated and control set plants especially with the study of leaf surface morphology by SEM (Scanning Electron Microscopy). A critical survey of leaf surface morphology by SEM revealed a number of interesting features out of which epicuticular wax deposition was very significantly distinguished. Thick deposition of wax, stomatal movement and armour of vascularization encountered very competently to overcome the stress biology of Sudan grass by enabling the extended crop life to a significant level.
