In this study, we usecell thermostability , chlorophyll fluorescence and leaf temperature to rapid and precisely select the heat tolerance varieties. In addition, for the heat intolerance varieties, we would improve the heat tolerance by chemical agents(e.g. salicylic acid, calcium chloride),fertilization and plant growth retardants.This program is planned to investigate the effects of various methods for improving the heat tolerance of poinsettia and set up a standard model of high quality and economical production of poinsettia potted plants in Taiwan.聖誕紅耐熱性水楊酸氯化鈣施肥矮化劑膜熱穩定性葉綠素螢光poinsettiaheat tolerancesalicylic acidcalcium chloridefertilizationplant growth retardantscell thermostabilitychlorophyll fluorescence
