Table 2.

Green leaf area, relative chlorophyll content, relative number of green leaves/plants, photosynthesis rate, and transpiration rate of the six stay-green introgression lines and their parents evaluated under control condition (W₁₀₀, 100% soil field capacity) and two post-flowering drought conditions (W₇₅, 75% soil field capacity; W₅₀, 50% soil field capacity).

WD: one week before drought; GF: mid-grain filling; LGF: late-grain filling; M: maturity. Different letters are significantly different (Fischer PLSD, P<0.05).
