Effects of Water Supply on Phenotypic Plasticity and Ecological Adaptability of Dracaena cambodiana Seedlings
Response of growth and morphology of Dracaena cambodiana seedlings,a rare and endangered plant,was studied by observing its response to five artificially controlled water supply levels.The results indicated that different levels of water supply significantly affected mor-phological indices and biomass.Except for specific leaf area,the ratio of leaf length to width and plant height,other indicators reached signifi-cant levels (P<0.05).The allocation of biomass is mainly related to root traits,and there is no significant difference in chlorophyll and carote-noid content among different treatments in seedlings. According to the analysis,the seedlings could make full use of water to achieve rapid growth in the short and concentrated rainy season,and allocating more biomass to the root was good for the severe drought season after the rainy season.In summary,the seedlings of Dracaena cambodiana had strong ecological adaptability to the survival strategy of water response.
