Abstract
Cassava (Manihot esculenta Crantz.) is the third most important crop in the world and a staple food source throughout the tropics. Indonesia is the second largest cassava producing country after Nigeria with an average total supply for five years of 9.67 million tons or 10.61% of the world's total supply of cassava. Cassava land centers in Indonesia are controlled by Lampung Province with a harvested area of 324,100 ha. This situation makes Lampung a supplier of one-third of the national cassava production of the national production of 23.92 million tons. However, there are still many production constraints in cassava cultivation, including drought stress. Drought stress is one of the main factors causing cassava plant death. So far, there is no drought-resistant cassava cultivar. The use of cassava seeds which are resistant to drought stress with high yields is expected to be an important alternative for drought stress control. One approach for drought stress induction is to use an osmotic compound with a high molecular weight, namely Polyethylene glycol 6000 (PEG 6000). So far the use of PEG 6000 in tolerant concentrations has never been reported with certainty and accuracy in inducing cassava resistance to drought stress. Physiological responses of plants to drought stress include the formation of reducing sugars and carbohydrates. The purpose of this study was to analyze the reducing sugar content and the total carbohydrate content of cassava plants which were resistant to drought stress. This study used a completely randomized design with one factor, namely the concentration of PEG 6000 consisting of 5 levels 0%, 10%, 20%, 30% and 40%. Data analysis used Analysis of Variance with a significance level of 5 percent. Data analysis used Anova analysis, and continued with Tukey's test at 5% significance level. The results showed that the higher the concentration of PEG 6000, the total dissolved carbohydrate content and reducing sugar content in cassava plants which were resistant to drought stress increased. The highest reducing sugar content and carbohydrate content were found in the treatment of 40% PEG 6000 concentration. Keywords: Cassava, reducing sugar, carbohydrates, drought stress, PEG 6000
