“…Ketan genotype with 100% FC water level has the highest number of stomata, 41% higher than Ketan genotype with 60% FC water level treatment. Observation of stomata density at black rice show that, the lowest water treatment resulting the lowest density of stomata as morphological response [21]. The numbers in the same column followed by the same letter are not significantly different based on the LSD test at the 5% level…”

This study aims to determine the response of growth and yield of taro plant genotypes to the level of soil water availability. The experiment was carried out using a divided plot design with the main plot being the rate of water application, namely: 60% FC (Field capacity), 80% FC, 100% FC, 120% FC and 140% FC, while the subplots were taro genotypes consisting of two types of dasheen (Ketan and California genotype), two types of eddoe (Satoimo and Jepang Hijau) also Xanthosoma (Talas Kuning). Parameters of plant growth observations included plant height, number of leaves, leaf area, stem diameter and width of canopy, while parameters of harvest observations included tuber fresh weight and total fresh weight. Physiological observations include chlorophyll content and number of stomata. Plant height of all types of taro was more vigor at 120 and 140% FC of water. For dasheen type taro, California taro with 140% FC treatment produced tuber fresh weight 36% higher than California taro plants at 60% FC treatment, while for Eddoetypetaro, Satoimo taro with 140% FC treatment produced tuber fresh weight 25% higher thanin 60% FC treatment. This proves that 5 genotypes of taro adaptive on waterlogging stress rather than drought stress. Satoimo and Jepang Hijau (eddoe type) are more adaptive to drought and wet soil conditions than talas Ketan, California and Talas Kuning (dasheen type).

Kacang bambara merupakan salah satu dari lima tanaman penting di Afrika selatan yang toleran terhadap kekeringan. Salah satu upaya peningkatan produktivitas tanaman kacang bambara dilakukan dengan cara pemilihan galur unggul dan menerapkan kebutuhan air yang optimal. Tujuan adanya penelitian ini adalah untuk mendapatkan kombinasi terhadap galur dan kebutuhan air yang optimal pada tanaman kacang Bambara. Pelaksannan penelitian ini dimulai pada bulan Agustus 2022 hingga Januari 2023 di dalam Greenhouse Lahan Percobaan Hollywood. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan dua faktor. Faktor pertama adalah jenis galur (G) yang terdiri dari 10 taraf G01 (JH89), G02 (JH67), G03 (JH41), G04 (JM76), G05 (JM48), G06 (G4M), G07 (G5MH), G08 (G5MC), G09 (No.8), dan G010 (Parental S19-3) sedangkan faktor kedua terdiri dari 2 taraf, yaitu V01(Volume Air 200ml) dan V02(Volume Air 400ml). keduanya dikombinasikan sehhingga diperoleh 20 kombinasi perlakuan dan masing-masing perlakuan diulang 5 kali. Variable pertumbuhan yang diamati yaitu laju perkecambahan, tinggi tanaman, jumlah daun, lebar tajuk, panjang petiole, panjang internode, bunga pertama dan 50% tanaman berbunga. Variabel hasil yang diamati yaitu jumlah bunga, jumlah polong per tanaman, bobot basah polong per tanaman, bobot kering polong per tanaman, bobot kering biji per tanaman, jumlah biji per tanaman, bobot 100 biji, bobot basah brangkasan, bobot kering brangkasan, panjang akar, bobot kering akar, persentase fruit set dan persentase kupasan. Pada penelitian ini Analisis data yang digunakan adalah Anova, dan uji DMRT 5%. Dari hasil perlakuan ini terdapat interaksi nyata pada perlakuan tunggal galur terhadap pertumbuhan dan hasil tanaman kacang bambara.

“…A repeated cycle of dry and watering conditions of mid-level and highlevel drought was maintained throughout the growing period. Furthermore, the three treatments were designed to reach a field capacity of approximately 80% (Control), 60% (Mid-level), and 20% (High-level) according to [9]). Observations were subsequently performed on both the qualitative and quantitative agronomical characteristics.…”

“…Observations were subsequently performed on both the qualitative and quantitative agronomical characteristics. The qualitative characteristics were indicated by the leaf rolling (Table 2) and dryness index (Table 3) according to [9]. On the other hand, the quantitative parameters of plant growth included 1) plant height, 2) the number and productivity of tillers, 3) the age of flowering, 4) the age of harvesting, and 5) the number of grains and filled grains per panicle.…”

The productivity of the rice plant is commonly influenced by both genotype and environmental factors. One common environmental factor that leads to harvest failure is drought, often caused by low rainfall. Therefore, the development of drought-tolerant varieties should be implemented to obtain optimum productivity under an unfavorable environment. One of the canonical approaches for achieving this is genetic manipulation, such as by gamma radiation-induced mutation. This study aimed to determine the drought tolerance and quantitative characteristics of mutant rice varieties generated from gamma radiation. The methodology used was a split-plot design with two factors, including drought as the first factor consisting of three groups namely control, mid-level, and high-level. The second factor was rice genotypes, which consisted of six genotypes comprising PMG 07/PsJ, PMG 08/ PsJ, and PMG 09/ PsJ (mutant varieties), Gajah Mungkur (parental background), Limboto (drought-tolerant), and IR 20 (drought-susceptible). The data were statistically examined using Analysis of Variance (ANOVA) and further analyzed with Duncan’s Multiple Range Test (DMRT) with a significance level of 5%. The results showed that high-level drought significantly affected plant height during both the vegetative and mature stages. Among the mutants, PMG 08/PsJ exhibited better vegetative growth under dry conditions, retaining a relatively higher height. Drought also had a negative impact on the number of tillers and productive tillers. The PMG 08/PsJ mutant had a slightly higher number of tillers under drought cultivations. On the other hand, PMG 09/PsJ was found to have a relatively more filled grain number per panicle. Leaf rolling and dryness index showed similar trends in all varieties, while drought treatments imposed a delay on the flowering and harvesting age. Although the results demonstrated no substantial improvement over the parental lines, the selected mutant lines provided several beneficial agronomical features such as maintenance of plant height, tiller number, and shorter life cycles under severe drought. These characteristics could serve as valuable genetic resources for breeding programs focused on developing drought-resistant rice varieties for challenging environments.
