Aluminum is prevalent in soils of tidal swamps. Soybean known to be very sensitive aluminum stress and so when swamps are converted soybean cropland, considerable effort expense required overcome Al toxicity roots. It therefore necessary determine at what time early development soybeans can best endure identify aluminum-tolerant cultivars. This study was conducted by testing the impact exposure on three cultivars (Tanggamus, Karasumame, M652) (relative no-exposure controls) four periods 10, 20, 30 days after planting. No significant effect root growth first five observed, but toxic effects became evident had been exposed for 10 days. seedlings that experienced earliest (at planting) were more negatively impacted than later (e.g., planting). Root growths we tested this all detrimentally exposure. However, M652 cultivar most We conclude critical threshold period succumb within planting, whereas tolerance occurs only during
