“…The increase in root dry weight, shoots dry weight, and root to shoot ratio in plants due to osmopriming correlated with the increase in root length. These results are in line with those of Latifa and Rachmawati (2020) which found a positive correlation between root length and dry weight of osmopriming Ipomoea reptans plants. A well-developed root system increases the reach of the roots in absorbing wider water so that more water and nutrients are available.…”

Salinity stress is a form of abiotic stress that threatens the sustainability of agriculture in almost all countries in the world. It has an impact in reducing plant productivity. Red amaranth (Amaranthus tricolor L.) is a vegetable crop that has high nutritional value, but extensive saline land area can cause red amaranth yields to decline. Osmopriming is a seed priming method in which seeds are immersed in a solution that has a high osmotic potential, such as PEG (polyethylene glycol) in order to increase germination under unfavorable conditions. This study determined the effect of osmopriming on germination, physiological, and root anatomical attributes of red amaranth roots under salinity stress conditions. The research design used a completely randomized design with two types of treatment, namely, osmopriming and salinity stress. Each treatment used three concentrations, seed osmopriming with 0%, 5%, and 10% of PEG and salinity stress of 0 mM, 50 mM, and 100 mM of NaCl. The measured parameters were germination, growth, physiological, and root anatomical characters. Osmopriming of seeds with 10% PEG increased germination as indicated by the germination percentage, time, and rate reaching 95.55%, 1.393 day, and 71.98%/day, respectively. Red amaranth plants that had been osmoprimed with 10% PEG grew faster when exposed to salinity stress. Application of PEG 5% and 10% increased total chlorophyll levels while decreasing proline levels and Ca-oxalate crystal density. Under salinity stress conditions, PEG application improved the root anatomical characters of red amaranth as shown by increased epidermis thickness, cortex thickness, and stele diameter. Priming application with 10% PEG has the potential to increase the tolerance of red amaranth to salinity stress.

Abstract. Prellia A, Solichatun, Pitoyo A. 2023. Induction of drought resistance in bell pepper (Capsicum annuum var. grossum) with osmopriming Polyethylene Glycol (PEG) 4000. Asian J Agric 7: 34-46. The bell pepper (C. annuum var. grossum) is an economically valuable chili cultivar. However, in Indonesia, the cultivation of bell peppers is hampered by drought stress. Osmopriming is an alternative method to improve seed quality. That method was used by soaking the seeds in osmoticum solutions, with Polyethylene Glycol (PEG) as the solution. This research examines the effect of osmopriming with PEG 4000 on the germination and growth of bell pepper seedlings under various drought stressors. In 2020, seeds were collected from ripe bell peppers grown by farmers in Surjo Hamlet, Sukabumi Village, Cepogo Sub-district, Boyolali District, Central Java, Indonesia. This study employed a Completely Randomized Design (CRD) with two parameters: PEG concentration and water capacity variations. The concentrations of PEG 4000 utilized were 0, 50, 100, and 150 g/L. The drought stress test is conducted by cultivating primed bell pepper seedlings in planting media with varying water capacities of 100%, 75%, and 50% Space Capacity (SC). Included in the drought group with a moderate stress level is a water capacity of 50% SC. Each treatment was replicated three times. Under drought stress, osmopriming with PEG 4000 accelerated the germination rate and affected seedling growth regarding height, number of leaves, leaf area, wet seedling weight, and shoot-root ratio. However, under drought stress, osmopriming PEG 4000 had no significant effect on the rise in proline and chlorophyll content nor on the decrease in carotenoids and nitrate reductase activity. PEG 150 g/L with 50% SC was ideal for seedling height, leaf number, leaf area, and wet weight, while PEG 100 g/L with 100% SC was optimal for the shoot-root ratio.

This study aims to determine the effect of different priming methods on the viability and early growth of upland rice under drought stress. Priming is an important approach to improve the resistance of upland rice plants to drought stress from the germination phase to growth, especially on sub-optimal land. There are several efficient priming methods as seed pretreatment to increase germination and tolerance to drought stress. An effective priming method is needed to increase the germination and growth of upland rice seedlings for application in dryland agriculture. Therefore, an experiment was conducted at the Seed laboratory of Pangkep State Polytechnic of Agriculture, Indonesia, from September to October of 2022 to investigate the effect of several priming methods on the germination and growth of upland rice seedlings under drought stress. The experiment consisted of 2 stages, germination testing and seedling growth phase testing with the addition of water stress treatment. Experiment 1 was conducted in a completely randomized design (CRD) with four replications, including Control (no priming), Osmopriming with 15% and 20% PEG solution, Redox Priming with 3% and 6% H2O2 solution, and Organic Priming using 50% and 75% Moringa leaf extract. Experiment 2 was conducted using a two-factor of factorial in Randomized Block design (RBD) with three replications. The first factor is the Seedling results of stage 1 experiments (selected the best of each priming method) includes 4 treatments each Control treatment, Osmopriming with 15% PEG solution, Redox Priming with 3% H2O2 solution, and Organic Priming with 50% Moringa Leaf Extract. The second factor is the level of Drought Stress conducted by 100%, 60%, and 30% of Field Capacity. The results showed that the priming method with Osmopriming 15% PEG solution gave the best results on Seed germination percentage (87.5%) followed by Organic priming with 50% Moringa Leaf Extract (SGP 85%). Under drought stress conditions with 30% field capacity, the highest increase in proline levels was observed with H2O2 redox priming 3% (10.3 µ-mol. g-1 ), while the average root growth of all primed seedlings showed better root growth than seeds without priming treatment. Seed priming gives better results on the growth and physiological activities of upland rice at several levels of drought stress, in the early growth phase of seedlings
