UJI KETAHANAN CEKAMAN KEKERINGAN MENGGUNAKAN POLYETHYLENE GLYCOL (PEG) 6000 PADA PADI LOKAL DAN NON LOKAL DI KABUPATEN MERAUKE

Abstract

Rice is the main agricultural commodity in Indonesia as a staple food source for most of the population. The increase of abundant population must be balanced with increased availability of food. The availability of rice germplasm is an important factor to support food availability. Local rice is a germ plasma that has resistance to biotic and abiotic stresses, but is less attractive to farmers for cultivation. This study aims to test the drought resistance of several local and non-local rice types found in Merauke district. The method used in this study was to germinate rice at various concentrations of PEG-6000. The research design used was factorial RAL with rice type factor (variety) and PEG-6000 concentration. The rice used in this study consisted of 2 types of rice, namely local rice and superior varieties of rice. Local rice used is Cempo Laut and Palenok which have long been cultivated by farmers in Merauke, while the superior varieties of rice used are Inpago 10 and IR 64. The concentrations of PEG-6000 used are 0%, 5%, 10%, 15% and 20%. Each sample was repeated 3 times, so that the total treatment was 4 x 5 x 3 treatments or as many as 60 treatments. Rice was germinated for 7 days at various concentrations of PEG-6000 after which the parameters tested were germination (DB), maximum growth potential (PTM, radicular length, and plumula length. The results of this study concluded that sea cempo rice showed drought resistance properties the germination and maximum growth potential parameters, while the length of the plumula and radicle is lower than that of Inpago 10 rice. Palenok rice does not germinate at a concentration of 0% and germinate at higher concentrations.
