Fruit-weight of Pitaya Raised Under Saline Habitats
-
摘要: 探讨了盐碱环境火龙果果实生长过程中全果、果肉和果皮的干、鲜重及水分变化情况。结果表明:盐碱环境下火龙果果实在整个生长过程中鲜重及干重的增长均呈双"S"型曲线,果实成熟时果实鲜重和干重积累量均达到最大值。在发育初期(花后6~15d)起以果皮生长为主,在发育中后期(花后21~35d)果肉在果实生长过程中占主导地位。水分支配着果实鲜重的增长,果肉生长过程中水分的最大增速在花后26~30d,在果皮和果实生长过程中水分的最大增速均在花后6~10d。Abstract: To study the fruit development of pitaya under saline habitats, weights of the whole fruit, flesh and peel, as well as the moisture contents and dry material were monitored. The results showed that pitaya fruit-weight increased in a "double S" curve as the plant grew in saline habitats. The weights of the fresh and dry fruits reached their maximums upon ripening. The peel played a predominant role on the weight gain in the initial growth stage (i. e. , 6--15d after flowering), while the flesh did in the mid-to-late growth stage (i. e. , 21--35d after flowering). Moisture content in the flesh dictated the fruit's weight gain. The greatest weight gain rate of the flesh occurred during 26--30d after flowering; and that of the fruit and peel, 6--lOd after flowerinm
