The results showed that glucose and fructose are primary soluble sugars from night to 10: 00 a.m. in mature leaves, but during 13: 00 - 16: 00 p.m., stachyose becomes the most abundant oligosaccharide, this diurnal change is mostly due to the tempestuous fluctuation of stachyose concentration in mature leaves. During photoassimilate transportation, the p rimary soluble sugar in phloem sap is stachyose. When transportation is finished, sucrose becomes the main sugar in phloem sap. Cucumber leavesmay store photoassimilate in the forms of starch, glucose, fructose, stachyose and sucrose at night. The concentrations of glucose, fructose and stachyose in phloem sap are much lower than in leaves at that time. There may be some unique mechanisms modulating source-sink translocation by which soluble sugars in leaveswere prevented from loading into the phloem further during night.

结果表明夜间至上午10： 00，葡萄糖和果糖是叶片中主要的可溶性糖，而下午13： 00至16： 00，水苏糖成为成熟叶片中含量最高的可溶性糖，这种变化主要由叶片中水苏糖含量剧烈的昼夜变化引起；当黄瓜同化物从源叶向外运输时，韧皮部汁液中的可溶性糖以水苏糖为主，运输完毕后则以蔗糖为主；黄瓜成熟叶片在夜间以淀粉、葡萄糖、果糖、水苏糖、蔗糖等各种形式贮藏尚未运出的同化物，而此时韧皮部汁液中葡萄糖、果糖、水苏糖的含量极低，可能有特定的源库调节机制阻止叶片中的可溶性糖在夜间进一步向韧皮部中装载。

The results shows that: the low canopy density environment can promote the height, leaf area, and other indicators of bush ivy in short-term; but the direct radiation of 13.16 molm^(-2) and the scattered radiation of 1.62 molm^(-2) are needed for the foster of stable and tolerant Fatshedera plants.

结果表明，在郁闭度低环境下，可以在短时间内促进熊掌木苗高、叶面积等指标；但为培育出株型稳定的熊掌木苗木，其培育的光照条件应设计为直接辐射13.16molm^(-2)、散射辐射1.62molm^(-2)，林分郁闭度调整为0.4、透光率达到60%的香樟林下培育苗木。

The results showed that the calorific values of the test plant species had no unified change pattern, which was possibly related to the partitioning ratio of calorific value in different plant organs and the timing when the reproductive period appeared. In general, spike had a higher calorific value than leaf and stem, and aquatic plants had obviously lower calorific value than mesophytes and wet mesophytes. Within a species, the change pattern of calorific value had certain relations to the phenophase, with approximately two lowest values and two highest values. Among the species, the differences in the calorific value were decided by the nature of the species themselves. Under the same habitat and climatic conditions, the species that contained more materials rich in energy could more easily accumulate calorific, and thus, more adaptable to grow under this environment.

结果表明：各物种的热值动态变化规律并不是统一的，这种变化可能与植物各器官热值的变化及生殖期出现的时间有关；各植物器官的热值普遍表现出穗的热值大于茎和叶；水生植物的热值明显小于中生性和湿中生性植物；种内热值变化随物候期变化有一定的规律，大约会出现2次低值、2次高值；种间热值差异是由于植物本身性质决定的，在相同生境和气候条件下，植物体中含能物质越多，就越易积聚热值，从而更适宜生长在此环境。
