Adaptasi Kecambah Padi Sawah (Oryza sativa L.) Varietas Ciherang dan Ciliwung terhadap Defisit Air yang Diinduksi Dengan Polietilen Glikol 6000

Ringkasan

The objective of this study was to know whether the seedling of the two varieties of lowland rice Ciliwung and Ciherang can grow well in condition of water stress induced by polyethylene glycol 6000. This research was conducted 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. Factor A was a lowland rice varieties with two levels : Ciherang and Ciliwung. Factor B was the polyethylene glycol 6000 with 3 levels : 0% w/v, 10% w/v and 20% w/v. Each combination of treatment was repeated 5 times. The number of experimental unit was 30. The variable in this study were 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 the LSD test at 5% significance level. The results showed that Ciherang have better growth characteristics than Ciliwung. Both varieties negatively responsed to polyethylene glycol 6000 indicated by a decrease in fresh weight, dry weight and total chlorophyll content, while shoots length Ciherang showed a positive response. During seedling growth Ciliwung more adaptive to drought than Ciherang varieties indicated by an increase in the ratio of root shoot and an increased proportion of roots. The final conclusion was that Ciherang more potential to develop in arid region than Ciliwung.
