摘要
4种扁桃在 6月幼果膨大期的光合速率排序为 :麻壳 >纸皮 >克西 >双果 ,其中麻壳品种的光合速率最高为 30 .2 2mg·dm-2 h-1。 9月份果仁成熟期 ,克西和双果的光合速率维持在 2 0 .30mg·dm-2 h-1,而纸皮和麻壳则降至 10 .5 2mg·dm-2 h-1;4种扁桃相对含水量从高到低排序为 :双果 >克西 >麻壳 >纸皮 ,4种扁桃在 6月份的细胞膜透性从大到小排序为 :克西 >双果 >麻壳 >纸皮 ,9月双果的细胞膜透性是 4种扁桃中最低的 ,从相对含水量和细胞膜透性上看双果具有较强的抗旱性。
The ordination of photosynthetic rate of four cultivars of Amygdalus communis L. During expansion period prematurely in June is as follows: Marc>Zhipy>Kexi>Shuangguo, the photosynthetic rate of Marc is the highest(30.22 mg·dm -2 h -1 ).The photosynthetic rate of Kexi and Shuangguo maintain 20.30 mg·dm -2 h -1 during fruit maturity in September, while Zhipy and Marc reduce to 10.52 mg·dm -2 h -1 . The RWC ordination of four cultivars is Shuangguo>Kexi>Marc>Zhipy in June,the ordination of membrane permeability is Kexi>Shuangguo>Marc>Zhipy in June,the membrane permeability of Shuangguo is the lowest in September, Shuangguo is relatively resistant to arid climate combining with RWC and membrane permeability of four cultivars.
