“…Using polyethylene glycol (PEG) 8000 to simulate water stress, the grains were placed in solutions with water potentials of 0, −0.1, −0.2, −0.4, −0.6, −0.8, −1.0, and −1.2 MPa, which was achieved by dissolving 0, 79.55, 118.94, 175.00, 218.14, 254.55, 286.65, and 315.67 g of PEG 8000 in 1 L distilled water, respectively [ 21 ]. All other conditions were the same as the germination experiment.…”

Volunteer wheat commonly occurs and spreads rapidly in the main wheat-producing areas of China, seriously impacting cultivated wheat production. Limited information is currently available regarding the adaptability and germination traits of volunteer wheat. Therefore, this study’s aim was to evaluate the effects of environmental conditions on the germination and emergence of volunteer wheat seeds through laboratory experiments. The results showed that the germination percentages and viability of volunteer wheat were significantly higher than those of cultivated wheat at a low temperature of 5 °C, and they were lower than those of cultivated wheat at high temperatures of above 30 °C. Compared to cultivated wheat, volunteer wheat was able to tolerate higher salinity and lower osmotic potential, especially long-dormancy volunteer wheat. The secondary germination ability of volunteer wheat was higher than that of cultivated wheat after water immersion. Furthermore, volunteer wheat could not emerge normally when the seeding depth was greater than 8 cm, and the emergence ability of the volunteer wheat was weaker than that of the cultivated wheats when the seeding depth was 4–8 cm, which indicates that the deep tillage of cultivated land could effectively prevent the spread of volunteer wheat. This study revealed differences in the germination characteristics of volunteer wheat and cultivated wheat under the influence of different environmental factors, which provides a basis for future studies concerning the control of volunteer wheat.

“…Berdasarkan hasil seleksi Violita & Azhari (2021), varietas padi memiliki tingkat kepekaan dan toleran masing-masing dalam menghadapi kekeringan. Hal tersebut dapat dikategorikan menjadi tiga tingkat ketahanan berdasarkan ISK (Indeks Sensitivitas Kekeringan) yaitu toleran (Harum dan Baroto), moderat (Situbagendit dan Randam Kaus), dan sensitif (Keriting, Batang Palo, Kuning Rendah, Indragiri, dan Rosna putih).…”

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.

“…Previous research has selected several rice varieties cultivated in West Sumatra. Selected rice varieties are grouped based on their of resistance to drought conditions, namely tolerant rice (Harum and Baroto varieties), moderate rice (Situbagendit and Randam Kaus varieties), and sensitive rice (Keriting, Batang Palo, Kuning rendah, Indragiri, and Rosna putih varieties) [11]. However, it is not yet known whether drought stress can disrupt the stability and integrity of DNA in rice.…”

Global climate change might cause a region to have a prolonged dry or rainy season. A long dry season can create drought stress in rice plants, resulting in Reactive Oxygen Species (ROS) compounds in cells and causing damage to plants, one of which is damage to DNA. The purpose of this study is to examine the stability of rice's genetic profile in order to assess the effect of drought stress treatment on rice DNA itself. Previous research classified three rice varieties into three groups based on their drought stress resistance: Harum (tolerant), Situbagendit (moderate), and Rosna (sensitive). These three rice plants were germinated and then treated with drought stress using PEG. Rice roots before and after being treated with drought stress were collected and the DNA was extracted. Genetic profile stability analysis was carried out by RAPD PCR using 10 types of primers. The DNA band patterns in rice samples before and after drought stress were differed, according to the electropherograms of ten RAPD primers and Jaccard's similarity index. This suggests that drought stress may disrupt the genetic stability of the three rice varieties studied.
