Abstract

This research aimed to determine the general combining ability and special combining ability of the cross-dialel crossing results of several varieties of rice plants using the Griffing method. The study was conducted in technical irrigated rice fields, the Experimental Garden of the Faculty of Agriculture, University of Mataram in the Village of Nyur Lembang, Narmada District, West Lombok Regency in February to July 2019. The experimental design used in this study was a Randomized Block Design (RAK) using the dialel Griffing II method consisting of 4 elders and F1 crossing results. The results showed that the results of the analysis of the combining ability of four rice elders and the results of crossing f1 using the Griffing II method. Of the seven characters have a positive joining power.

Abstract

Pohon penghasil gaharu yang paling terkenal dari suku Thymelaeaceae salah satu diantaranya adalah spesies dari marga Gyrinops, contohnya G. versteegii provenan Beringin. Pohon ini umumnya dapat ditemukan di kawasan Indoneria bagian timur, khususnya yang tersebar di Pulau Lombok. Pohon ini dapat menghasilakn gubal gaharu, namun di alam sering dijumpai walaupun telah berusia puluhan tahun belum memproduksi gubal gaharu. Solusinya adalah menyeleksi bibit yang dapat menghasilkan gubal kelas super secara in vitro. Salah satu tahapan adalah mengobservasi kandungan metabolit sekunder menggunakan metode histokimia. Tujuan dari penelitian ini adalah mengetahui jenis kandungan senyawa metabolik primer dan sekunder yang terkandung di dalam jaringan kalus G. versteegii provenan Beringin. Penelitian ini dilaksanakan di Laboratorium Biologi Lanjut 3.4 dan Laboratorium Imunologi FMIPA Universitas Mataram. Kalus yang dihasilkan dari daun G. versteegii provenan Beringin dibuat preparat histokimia. Hasil pengujian histokimia terhadap kalus daun G. versteegii provenan Beringin menunjukkan bahwa di dalam sel kalus tersebut mengandung metabolic sekunder berupa amilum dan senyawa metabolik sekunder berikut: alkaloid, flavonoid, lipid, sesquiterpene dan terpenoid.

Abstract

Drought and shade stress often occur together in peanut plants. Sunlight and water are the main factors that determine the growth of peanut plants. This study aimed to determine the behavior of several peanut genotypes under conditions of sunlight and water deficit. This research was conducted using a Completely Randomized Design-Split Plot Design with three replications. The treatments to be tested were double stresses (sun light and water deficit) and no stress (control) factors as the main plot and peanut genotype factors, namely Takar-1, Domba, Bison, G2T5, and G19-UI as subplots. The results showed that the peanut genotypes had different behaviors under double stresses (sunlight and water deficit). Peanut plants under double stress caused a reduction in pod dry weight, number of pods, root dry weight, and chlorophyll-a levels compared to those without stress. Peanut genotype G19-UI resulted in the lowest percentage reduction in pod dry weight and number of pods per plant, namely 58.79% and 43.75% under double stresses, respectively

Abstract

Sorghum production needs to be increased to meet food or feed needs because sorghum grain has nutritional qualities that are comparable to other grains such as corn. One of the advantages of the sorghum plant is the growth of new shoots from the base of the harvested stem which produces new plants, ratoon, that grow until they can be harvested. This experiment examines the ratoon potential of 5 sorghum varieties, Bioguma, Samurai, Pahat, Suri4, and the local Gando Keta variety so that we can utilize ratoon technology on these sorghum varieties. The experiment was carried out in a greenhouse using a Completely Randomized Design. It can be confirmed from this experiment that the dry matter weight of the main plants is higher compared to the ratoon plants' dry matter weight, however, the yield of the ratoon was higher than that of the main plants. Seed size contributes to the higher yield of the ratoon plants.  Among all the varieties tested, Suri4 and Pahat show the best ratoon potential. Gando Keta, the local variety, has the lowest grain yield of main and ratoon compared to the other varieties.
