Evaluation of Drought Tolerance of the Vietnamese Soybean Cultivars Provides Potential Resources for Soybean Production and Genetic Engineering
Figure 4
The root and shoot developments under normal (black bars) and drought (grey bars) conditions of 13 soybean cultivars and the reference cultivar W82. For drought treatment, water withholding was applied to 12-day-old plants for 15 days. SMC was recorded in each pot of each cultivar at 5-day intervals. (a) SMC was measured under well-watered condition. (b) SMC was measured under drought condition. Error bars represent standard error (). (c) Tap root length. (d) Shoot length. (e) Root DM. (f) Shoot DM. Error bars represent standard error (). Different letters indicate significant difference within a treatment according to Duncan’s test ( level).
