Abstract

Germination is the initial stage of plant growth and plays a crucial role in determining the success of crop cultivation. One factor influencing germination rate is the pre-treatment of seeds before planting. This study aimed to examine the effect of warm water soaking on the germination rate and percentage of mung bean (Vigna radiata) seeds. The experimental method used four treatments: P0 (no soaking/control), P1 (soaking at 40°C), P2 (50°C), and P3 (60°C), each for 6 hours. The results showed that warm water soaking significantly affected both germination speed and percentage. The P2 treatment (50°C) produced the best results, with the earliest germination (day 1) and the highest germination percentage (95%) by day 7. In contrast, soaking at 60°C resulted in a lower germination rate, likely due to damage to seed tissues. It can be concluded that soaking mung bean seeds in warm water at 50°C for 6 hours is the most effective treatment to enhance germination speed and success.

Abstract

This study aimed to analyze the effect of shading on the growth and photosynthetic rate of red chili pepper (Capsicum annuum L.). The results showed that shading treatment had a significant effect on morphological parameters, namely plant height and total dry weight, but did not significantly affect leaf width, leaf number, and leaf length compared to plants grown without shading. Physiologically, shading influenced quantum yield, photochemical quenching, and non-photochemical quenching, whereas the maximum photosynthetic rate (Pmax) did not show a significant difference. From an ecophysiological perspective, shading treatment significantly increased proline and ascorbic acid contents. These findings indicate that red chili pepper exhibits a high adaptive capacity to low light intensity conditions. This study is expected to contribute as a reference material and learning resource in the fields of plant physiology and plant biology.
