CO 2 concentration was higher in November and March and lower in May. The pattern of diurnal variation of CO 2 concentration among seasons was similar,decreased with the increasing of photosynthetic and reached the lowest at 12:00-14:00 PM,then increased with the decreasing of photosynthesis. The major factors af...

   2002, 1 (1): 13-15.  
Abstract （2143）      PDF（pc） （151KB）（2281）       Save
Using root cutting and shoot cutting,by means of the orthogonal design propagation of Toona sinensis was carried out. The results showed that root cutting was superior to shoot cutting,and long cutting was better than short cutting for propagation. There were some difference in rooting positions between the root cutting and the short cutting,Adventitious roots developed from callu and corium for the shoot cutting and root cutting respectively. Cutting propagation using root and shoot cutting could be us...

Li Guojing;F.Benoit;N.Ceustermans
   2002, 1 (2): 4-8.  
Abstract （932）      PDF（pc） （232KB）（892）       Save
The aim of the present research was to determine the possibility of the application of Mechanical Brushing (MB) during the nursery to prevent excessive growth instead of plant growth retardants. The intensity of MB was regulated by the time when the seedlings were subjected to MB and the density of the plastic slices. The results showed that MB significantly retarded plant elongation,reduced the intertruss length and increased the ratio of stem diameter to plant length. The sensitivities of sweet pepper,tom...

Abstract （1341）      PDF（pc） （491KB）（1633）       Save
The differences of various cauliflower cultivars in leaf activities of peroxidiase and nitrate reductase and cell ultrastructure under drought stress were investigated. The results showed that under drought stress,POD activity in all cultivars increased while NR activity increased only in late maturing cultivars and decreased in early and mid maturing cultivars. The changes of chloroplasts and mitochondria also varied with cultivars. In early and mid maturing cultivars,the chloroplasts became more rou...

Abstract （1032）      PDF（pc） （192KB）（904）       Save
Four tomato cultivars, Baiguoqiangfeng, Jiafen, Hezuo 903 and Jiangshu No.1 were studied on Ca uptake and transportation in the plant at the seedling stage in the condition of Ca deficiency by using solution culture. The results showed that the amounts of the absorbed Ca by seedlings under the normal supplement of calcium (CK) were significantly different among the four cultivars, the detailed order from large to small is as follows: Baiguoqiangfeng, Jiafen, Hezuo 903 and Jiangshu No.1. The absorption of Ca...
