The results showed that the total amount of photosynthetic pigments in space flighted seedlings were lower due to significant reduction of chlorophyll a+b content .

因而近年来植物空间诱变的研究十分踊跃，但研究对象多集中于农作物和蔬菜，花卉植物的报道极少，且研究工作多集中在田间观察、形态学等内容[5] 。

The growth of H. fusiformis was determined by weighting the fresh algae every two days and the photosynthetic oxygen evolution was assayed by a Clark-type oxygen electrode. To determine the contents of chlorophyll a and UV-absorbing compounds, methanol extracts from H. fusiformis were scanned from 250 to 750 nm. The concentration of chlorophyll a was calculated using the equation of Porra and the contents of UVAC per fresh mass were estimated by determining the ratio of UVAC to chlorophyll a according to Dunlap et al and multiplying the ratio of chlorophyll a content to fresh weight of the sample used.

羊栖菜的生长是通过每两天测量一次藻体的湿重来测定的，光合放氧是用Clark型氧电极测定的，为了测定藻体叶绿素a和紫外吸收物质的含量，从250 nm到750 nm对羊栖菜的甲醇提取液进行扫描，叶绿素a的浓度用Porra的公式计算，紫外吸收物质的计算是根据Dunlap的方法先计算紫外吸收物质和叶绿素a的比率，然后乘以每单位藻体叶绿素a的含量。

In order to evaluate the effects of important ecophysiolorical factors, such as light intensity, temperature, relative humidity, leaf structure(SLW, specific leaf weight; and SLA, specific leaf area) etc., on the net photosynthetic rate of Gordonia under natural conditions, the diurual and seasonal variations in Pn are measured with the improved dry-weight method.

Result Wild castor preformed better in halophilism than that of cultivar castor Zibi 6 under the NaCl treatment. One of the salt tolerant mechanisms of castor is to improve K(superscript +) uptake and transport to overground portion, thus to maintain K(superscript +)/Na(superscript +) homeostasis in leaves; on the other hand, the high stability of Photoreaction System Ⅱ plays a key role in maintaining the leaf photosynthetic rate under salt stress.

结果］野生蓖麻较栽培蓖麻具更明显的喜盐特性；蓖麻的耐盐机制在于促进K的吸收和向地上部的运输，进而维持叶片的K/Na平衡；通过维持光系统Ⅱ的稳定性进而维持盐胁迫下叶片的光合速率。
