以2个蝴蝶兰品种为材料，在广州地区和西藏林芝地区2个试验点条件下，比较不同品种在不同生态环境下的农艺性状差异，并利用叶绿素荧光仪检测分析各品种叶片叶绿素荧光特性。结果表明，种植于林芝地区的‘大辣椒’蝴蝶兰的光化学量子产量Y(Ⅱ)和电子传递速率ETR与广州地区的差异显著，而‘绿熊’蝴蝶兰的差异并不显著，说明‘绿熊’蝴蝶兰对林芝地区的环境适应性比‘大辣椒’蝴蝶兰好；另外，种植于林芝地区的蝴蝶兰FV/FM均显著低于广州地区，说明林芝地区的种植环境较广州地区不利于蝴蝶兰生长。
Two Phalaenopsis cultivars, ‘big chili’ and ‘green bear’, were used for the field experiment, carried out in Guangzhou and Nyingchi of Tibet. Agronomic characteristics of the varieties in different eco-environments were compared, and their chlorophyll fluorescence characteristics were measured by portable modulated chlorophyll fluorometer. The photochemical quantum yield [Y(II)] and electron transport rate (ETR) of ‘big chili’ in Nyingchi were significantly different from those in Guangzhou, but those of ‘green bear’ in Nyingchi were not significantly different from those in Guangzhou. It was showed that environmental adaptability of ‘green bear’ was higher than that of ‘big chili’. FV/FM of the two Phalaenopsis cultivars in Nyingchi were significantly lower than those in Guangzhou, showed that planting environment in Nyingchi was not conducive to the growth of Phalaenopsis.
