Results The UV-B treatment caused the declines of chlorophyll content, soluble protein content and water content of leaves, besides, dose-effect was existed. The decline of 30 μW/cm^2 treatment was bigger than that of 15 μW/cm^2 treatment. The influences of UV-B radiation on carotenoid content and anthocyanidin content were similar; the change trends were declined firstly then increased. The UV-B treatment with two doses restrained the electron transport of PSⅡ, particularly; the inhibitory effect was biggest after treated 2h, and then this effect was declined in 4, 6 and 8 h, so the dose-effect was existed. The UV-B radiation with two doses restricted photosynthetic rate and the inhibitory effect increased with the increase of treatment time. The high dose treatment caused huge damage to membrane system, while the result of low dose treatment was not obvious.

结果］UV-B处理导致叶绿素、可溶性蛋白含量以及含水量都降低，且存在剂量效应，30μW/平方公分处理的降幅大于15μW/平方公分；UV-B辐射处理对类胡萝卜素含量的影响与花青素相同，均表现为先下降后上升的趋势，2种剂量间差异不大；2种剂量的UV-B处理均抑制了PSⅡ的电子传递，尤其是处理2 h的抑制作用最大，4、6和8 h的抑制作用有所缓解，且存在剂量效应；2种剂量的UV-B辐射均抑制了叶片的光合速率，随着照射时间的延长抑制效应加大；高剂量UV-B处理对膜系统的损伤较大，低剂量UV-B处理结果不明显。

Grew on the normal temperature, it was shown that the deposits of calcium antimonate being the indicator for Ca(superscript 2+) localization mainly concentrated within the vacuoles and intercellular spaces and there was also some Ca(superscript 2+) deposits in cell walls. But when Garyota urens L. was treated by the temperature of 2℃ for 48 h, the level of Ca(superscript 2+) increased in cytoplasm and plasma membrane, but decreased in vacuoles and intercellular spaces considerably. At the same time, the ultrastructure of chloroplasts suffered from chilling: the membrane of chloroplasts had been damaged, the layer of thylakoids was exiguous and unclear, the photosynthetic rate decreased evidently. And when Garyota urens L. was treated by the temperature of 2℃ for 120 h, the deposits of Ca(superscript 2+) mainly concentrated within the cytoplasm, nucleus and plasma membrane and there was also some Ca(superscript 2+) deposits in vacuoles, and the ultrastructure of some cells was simultaneously damaged severely: Chloroplasts structure, vacuole membrane and nuclear membrane had been damaged fully, the structure within the cell had become unclear, and the cell only have respiration.

研究结果表明，未经低温处理的董棕幼苗叶肉细胞，焦锑酸钙沉淀颗粒大量出现在液泡和细胞间隙中，细胞壁中也可见少量沉淀，而细胞基质中则看不到焦锑酸钙沉淀；经2℃ 48 h低温处理后，细胞基质和细胞膜上焦锑酸钙沉淀增加，而液泡和细胞间隙中的焦锑酸钙沉淀则显著减少，并且超微结构已初步显示出寒害的特徵，叶绿体外膜部分破损，类囊体片层稀疏且排列不规则，光合速率明显下降等；经2℃ 120 h低温处理后，细胞间隙内的焦锑酸钙沉淀极少，有的也紧贴在细胞外壁上，而细胞基质和细胞膜上则分布有非常多的焦锑酸钙沉淀，在核基质和液泡中也可见到少量的焦锑酸钙沉淀，并且超微结构遭到了显著破坏，叶绿体结构完全被破坏，核膜与液泡膜严重破损，内部结构模糊，细胞只表现为呼吸作用，不进行光合作用。

The seedlings of 4 dominant tree species of tropical seasonal rain forest, such as Pometia tomentosa, Barringtonia macrostachya, Myristica yunnanensis and Knema globularia, were transplanted at three altitudinal sites (low 600 m in Menglun; middle 1 100 m in Caiyanghe; high 1 600 m in Mengsong) in Xishuangbanna. The parameters of photosynthesis and biomass of these seedlings were measured. The results showed that the low temperature at high altitude caused dormancy or photosynthetic system destroy.
