Abstract

Drought stress affected growth and decreases rice yield. The use of high yielding varieties and drought tolerance is a strategic step that can be applied during drought stress. The aim of this research was to examine the response of the growth of IPB 4S rice varieties on planting media with drought stress during vegetative phase. The research used a nonfactorial Completely Randomized Design with six levels: field capacity, 10% of field capacity, 20% of field capacity, 30% of field capacity, 40% of field capacity, and 50% of field capacity. The treatments were repeated three times. The growth parameters were plant high, number of tiller, leaf color, leaf area, root length, root dry weight, canopy dry weight, and biomass. The results showed that the drought stress significantly different to leaf area, root length, canopy dry weight, and biomass but were not significantly different to plant height, number of tiller, leaf color, dan root dry weight. Increased of drought stress 30 to 50% of field capacity decreased of leaf area, canopy dry weight, and biomass, but increased root length.

Abstract

Introduction: Salinity is a major constraint in rice crop production through inhibiting the absorption of water and minerals. The seedling age optimally can increase the adaptability of plants under saline conditions. The objective of this study was to examine the agronomic, physiological, and biochemical responses of rice under saline conditions using the different seed age to determine their adaptability to the abiotic stress. Methods: The study used a CRD non-factorial, there is seedling age with three levels including 21, 28, and 35 days after sowing (DAS). The study used rice cv. Banyuasin and salinity stress given is NaCl with the concentration 8 dS m-1. The addition of NaCl when the plants were 12 and 54 days after planting (DAP). Results: The different seed age planted under saline conditions significantly affects to agronomic and physiological characteristics as indicated by shoot dry weight, plant biomass, and chlorophyll content. The different seed age planted under saline conditions significantly affects biochemical characteristics as indicated by proline content and nitrate reductase activity. The rice seedling age of 21 DAS produced the highest biomass and shoot dry weight, the rice seedling age of 28 DAS produced the highest chlorophyll content and nitrate reductase activity, and the rice seedling age of 35 DAS produced the highest proline content. Conclusion: The older rice seedling (35 DAS) increased the higher proline content, while the younger rice seedling (21 DAS) increased the shoot dry weight and plant biomass. In addition, rice seedlings (28 DAS) produced the highest chlorophyll content and nitrate reductase activity.
