Abstract

Rice is an important food crop that consumed by more than half of the world's population, but almost every year there is decrease rice production in field, this is due availability of land and water as main source of agriculture. Therefore optimization of dry land as agricultural is needed, but many things are of concern to dry land, especially water sources are minimal. Therefore, it is need have rice seeds are suitable and adaptive to dry land, the response of rice plants to drought can observed from physiological, morphological and anatomical changes. This research was conducted in August to December 2018 in research laboratories, wire houses and plant physiology laboratories, Faculty of Mathematics and Natural Sciences, Padang State University. This study was to obtain a drought tolerant morphological index from several paddy seeds in West Sumatera, so indexes showed that rice seeds were tolerant to drought by observing morphological changes, namely leaf rolling (DPD), shoot top index (IKP). ), and plant recorvry (TP) using the SES (Standard Evaluation System) method for rice. Data is processed using cluster analysis with hierarchical analysis methods. The results showed the most resistant varieties to drought stress were’s Baroto, Situ Bagendit, Randah Kuniang, and Harum.

Abstract

Rice is the main food source for Indonesians. The demand for rice to meet people's needs increases every year due to population growth and efforts to improve nutrition by the community. One of the problems that can affect rice production is drought. Drought is an environmental condition when plants do not get enough water to grow and develop optimally, which can cause a decrease in rice production. To find out how rice growth responds to drought, a study was carried out by giving drought simulation treatments using polyethylene glycol (PEG) on several rice varieties. This study used a completely randomized design that was arranged in a factorial manner with two factors. The first factor was the rice varieties (Harum, Situbagendit, Rosna) the second factor was 0% and 20% PEG concentration. The data obtained were then analyzed statistically using a two-way ANOVA test, and if the results were significantly different, then proceed with Duncan's test at the 5% level.The results showed that the drought simulation treatment had a negative effect on rice growth. Drought simulation treatment using 20% PEG resulted in a decrease in Kadar air relatif (KAR), root length, plant height, and root dry weight of rice. The highest decrease in KAR was found in the sensitive rice variety (Rosna), which was 43.42%. The highest average root length (7.99 cm) was on the sitabaendit variety, and the lowest (5.61) was on the rosna variety. The highest average crown height (17.32 cm) and the lowest (6.61) were on the rosna variety.

Abstract

Rice has become food for most of the world's population. Indonesia is the third largest producer in the world. However, in fact rice production in Indonesia has decreased by 0.43% compared to 2020. One of the factors that can cause this decline is drought. Because rice is a semi-aquatic plant that grows normally in flooded conditions, it makes drought stress very threatening. Drought stress that occurs in plants causes plants to experience oxidative stress due to excessive accumulation of ROS. PEG is a compound that is widely used to provide drought conditions in plants. Previous research has classified several varieties of rice plants based on their level of resistance to drought. However, it is not yet known how the morphological response will be in different periods of drought stress and rewatering treatment. This research was conducted by giving treatment in the form of control (Yoshida nutrient culture solution) and drought stress (Yoshida + PEG-6000 20% solution) repeated 3 times. The observed parameters were RWC which were analyzed using standard errors and morphological images of roots and leaves. The results showed that the RWC obtained during the stress period from the third to the fifth day, Harum had the highest value according to its class as tolerant rice. After rewatering Rosna has a better recovery ability. In addition, root morphology shows differences in the form of root length, small root diameter, inhibition of adventive root growth. On the leaves include a decrease in leaf area, leaf curl up, and leaf yellowing.
