Abstract

Abstract Research to determine the effect of several salt concentrations on several tidal local rice varieties in Indragiri Regency. The research was conducted in the wire house of the Faculty of Agriculture from March to June 2020. This research used a completely randomized factorial design with 2 treatment factors, namely variety and salt concentration. The variety factor consisted of the Frog, Lemongrass, Karya, Arum and Super varieties. The salt concentration factor consisted of 0 nM, 100 nM, 200 nM and 300 nM. IR 64 which is salt sensitive is used as a control variety. All varieties of rice were sown in tarpaulins with mud as the medium. Rice seeds that are 14 days old are transferred to polybags. Rice is watered with tap water twice per day for two weeks. After two weeks of watering, the rice was then flushed with NaCl according to the treatment twice per day. Salt watering was stopped when one of the lines died (salt sensitive lines) then continued with watering with tap water twice per day for two weeks. The influence of the salt concentration given to the Serai variety showed that leaf width, number of tillers and root length were quite tolerant at concentrations of 100 – 300 nM, while the Super variety produced smaller number of tillers, leaf width and root length compared to other treatments, especially at a salt concentration of 300 nM.

Abstract

Similarity analysis was carried out on the characteristics of local type tidal rice grain in Indragiri Hilit Regency in January-October 2015 in Indragiri Hilir Regency. This research aims to inventory, characterize and determine the relationship between each type of local tidal rice grain in Indragiri Hilir Regency. This research uses a qualitative-quantitative description method. The beginning of this research was to explore the types of rice grains in each village and sub-district of Indfagiri Hilir Regency, then they were characterized and analyzed using the agglomerative method by calculating the distance between relatives using hierarchical cluster average linkage (between gropus). The research results show that Indragiri Hilir Regency has 27 local tidal rice cultivars. These cultivars consist of 'Karya Kuning', 'Karanduku', 'Ramos', 'Pulut Putih', 'Pandan Wangi', 'Ordinary', 'Lembu Sawah Merah', 'Karya Merah', 'Pulut Hitam', ' Pariaman', 'Lembu Sawah', 'Karya Tinggi', 'Panama', 'Batang Tuaka', 'Ir Super', 'Batang Piaman', 'Maron', 'Merah Putih', 'Serang', 'Putri Malu', 'Super', 'Opium', 'White', 'Kuatik', 'Frog', 'Lentik Bamban', 'Sere'. Morphological characters that differentiate rice cultivars are grain characteristics (length, width, thickness, weight of 100 seeds, grain surface shape, grain surface color, sterile lemma length, grain tip color, grain tip tail feather color and grain tip tail feather length), character rice (length, width, thickness, ratio of length to width, and color of rice epidermis). Phenetic analysis using the Minitab Release version 17 program divided 27 local tidal rice cultivars into 9 clusters at a similarity level of 56.78%. Which consists of group 1, consisting of Karya Kuning, Karya Merah, Maron, Pulut Putih, Putih, Putri Malu, Merah Putih, Super; Group II consists of Karanduku, Opium and Lembu Sawah Merah; cluster III consists of Ramos, Batang Tuaka, Karya Tinggi, Serang and Pariaman, cluster IV consists of paddy cattle; Group V consists of Kuatik, Serai, Lentik Bamban, Kodok, Group VI consists of Ordinary and Batang Piaman and groups VII, VIII and IX respectively consist of Pandan Wangi, Super and Pulut Hitam.
