heat tolerance index

基本解释

Firstly, the impact of temperature on cyclamen seedling growth was studied, and the physiological traits of the heat tolerance and heat tolerance index in seedling stage were analyzed.
首先，研究了不同溫度對仙客來幼苗生長發育的影響，對苗期耐熱性生理基礎及耐熱性指標篩選進行了分析。
Meanwhile, the fibrous roots, the number of leaves, the thickness of leaves and epidermis of leaves in cyclamen seedlings could be used as their morphological index for heat tolerance qualification.
耐熱性較強的法國和日本仙客來品種死亡率較低，而耐熱性較弱的荷蘭品種死亡率較高，表明死亡率也可以作爲鋻定仙客來耐熱性的一個間接指標。
