Pengaruh Asam Askorbat terhadap Ketahanan Cekaman Garam Padi Gogo (Oryza Sativa L.) Varietas Situ Bagendit

Ringkasan

The purpose of this study was to know whether ascorbic acid can increase the resistance of upland rice varieties Situ Bagendit to salinity (Salt stress). This research was carried out in the Laboratory of Plant Physiology, Department of Biology, Faculty of Mathematics and Natural Sciences, University of Lampung in December 2014 in a 2x3 factorial experiment. A factor: NaCl with 2 levels 0mM, and 25 mM. Factor B: ascorbic acid with 3 levels 0% w/m, 10% w/v, 20% w/v. Each combination of treatment was repeated 4 times. Variables in this study ware shoot length, fresh weight, dry weight, and total chlorophyll content. Data was analyzed using ANOVA at 5% significance level and proceed with the determination of a simple effect with LCD test at 5% significance level. The results showed that the growth of seedling upland rice was better in salin condition (salt stress) than in non condition. Shoot length, fresh weight, dry weight, and total chlorophyll content ware higher in salin condition than in non salin condition. ascorbic acid lowers shoot length, fresh weight, dry weight, and total chlorophyll content both salin and non sallin condition.. The final conclusion was that of ascorbic acid 10% w/v and 20% w/v can not increase the growth of upland rice seedling in salin condition (salt stress).
