摘要/Abstract

摘要： 研究了人工培养条件下基质盐度对红树植物木榄(Bruguiera gymnorrhiza)幼苗的热值、干物质及能量积累的影响.结果表明,木榄幼苗干物质和能量的积累存在低盐促进和高盐抑制的现象,其最大值出现于盐度10mg·g^-1处;随基质盐度的提高,木榄幼苗的干物质和能量积累倾向于叶片及细根等光合作用场所和养分吸收器官,木榄幼苗各器官干重热值及去灰分热值有不同的变化规律,其中叶片热值的变化规律能较好地反映木榄幼苗抗盐性的变化情况.本文从能量学角度探讨了红树植物的抗盐生理生态.

Abstract: The study with artificial culture showed that the accumulation of dry matter, energy in Bruguiera gymnorrhiza seedlings was promoted by low substrate salinity,but inhibited by high substrate salinity,which peaked at 10mg·g ^-1 substrate salinity.With the increase of substrate salinity, the dry matter, the energy tended to be allocated to the micro-roots, leaves, which are nutrient-absorbing organ, photosynthetic organ, respectively.With the increase of substrate salinity, the changes in caloric values were differed in various organs of B. gymnorrhiza seedlings,and those in leaves could reflect the changes in the salt-resistance of the seedlings.

Key words: Mangroves, Bruguiera gymnorrhiza, Salt stress, Caloric value, Energy, nonstructural carbohydrate, fine root respiration, soil warming, respiration acclimation
