图2. 盐胁迫下菠萝蜜和面包果幼苗生物量与光合参数相关性分析
TDW：总干重;RRS：根冠比;SPAD：叶绿素含量;Photo：净光合速率;Cond：气孔导度;Ci：胞间CO₂浓度;Trmmol：蒸腾速率。“*”表示不同处理间的差异显著性检验达0.05水平;“**”表示不同处理间的差异显著性检验达0.01水平。蓝色表示正相关,红色表示负相关,圆形的大小说明相关性的大小

Fig. 2. Correlation between the biomass and photosynthetic parameters of jackfruit and breadfruit seedlings under salt stress
TDW: total dry weight; RRS: ratio of root/shoot; SPAD: chlorophyll content; Photo: net photosynthetic rate; Cond: stomatal conductance; Ci: Intercellular CO₂ concentration; Trmmol: Transpiration rate. “*” indicates significant difference at 0.05 level; “**” indicates significant difference at 0.01 level. Blue indicates a positive correlation, red indicates a negative correlation. The size of the circle indicates the magnitude of the correlation
