Ultrastructure and Ca2+ Distribution in Anther Wall during Development of Photosensitive Genic Male-sterile Line of Rice Nongken 58S XIA Kuai-fei, DUAN Zhong-gang, LIANG Cheng-ye, YE Xiu-lin 2005, 34(03): 1-4.  Abstract ( )   PDF (1005KB) ( )   Using potassium antimonate technique, the ultrastructure and Ca2+ distribution in anther wall of photo-sensitive genic male-sterile line of Nongken 58S were studied. The results showed that under the long-day photoperiod, some vacuoles and Ca2+ precipitates were found in the tapetal cells in anther wall at pollen mother cell stage. With the growth of the plants, Ca2+ precipitates in the cells of anther wall increased, and it was mainly distributed in tapetal cells and on the surface of the Ubish bodies. Under the long-day photoperiod, the tapetal cells could not form intergraded Ubish bodies and the Ca2+precipitates on Ubish bodies were much less than that under the short-day photoperiod.

The results showed that in the present of O2· and ethylene, the activity of amylase could exhibit and made the fruit soft and ripe. Otherwise, might O2· have different effect from OH· in synthesis of ethylene. Related Articles | Metrics

Influence of Scion on the Growth and Some Physiological and Biochemical Characters of Rootstocks for Citrus ZHOU Kai-bing, GUO Wen-wu, XIA Ren-xue, HU Li-ming, HUANG Ren-hua 2005, 34(03): 11-14.  Abstract ( )   PDF (190KB) ( )   Using Citrus unshiu cv. Guoqingsihao and C. sinensis as scions, the growth and some physiological and biochemical characters of rootstocks i.e. C. reticulate+Poncirus trifoliate, C. reticulate+C. jambhiri, C. sinensis×P. trifoliate, C. grandis×P. trifoliate, P. trifoliate, (the not grafted rootstock as control), for citrus were studied through two years potted experiment. The results were as follows:the trunk diameter of C. grandis×P. trifoliate and C. reticulate+C. jambhiri rootstocks would be easily influence by scions. There existed significant differences in root system volume between grafted rootstock and not grafted rootstock. The root activity and the activities of SOD and POD in roots of grafted rootstock were not greater than those of not grafted one. The scions improved the activity of CAT in roots of rootstock.

Effects of Three Agricultural Practices on Arbuscular Mycorrhiza Development in Citrus WU Qiang-sheng, XIA Ren-xue 2005, 34(03): 15-17.  Abstract ( )   PDF (186KB) ( )   The effects of application of N fertilizer (2L 0.5% carbamide), covered ruderals (about 5 to 6 cm thick) and tillage (only 20 cm thick soils for two times) on root mycorrhizal colonization and spore density of two citrus (C. unshiu cv. Guoqing No.1/Poncirus trifoliata and C. unshiu cv. Guoqing No.4/Poncirus trifoliata) were investigated in field. The results showed that covered ruderals significantly enhanced the spore density of two citrus. Application of N fertilizer significantly decreased the spore density; and tillage significantly inhibited the root mycorrhizal colonization of two citrus. Root mycorrhizal colonization was significantly positive correlated with spore density in two citrus. Related Articles | Metrics

Species Form Feature of Evergreen Broadleaved Forest in Nature Reserve of Castanopsis kawakamii in Sanming City,Fujian Province SONG Yu-hong, QIU jin, RUAN Xun-qing, LI Jia-he 2005, 34(03): 18-22.  Abstract ( )   PDF (303KB) ( )   Based on the data collected from sample plots with an area of 11 000m2, the species composition, the types of distribution and species diversity of the evergreen broad-leaved forest community in Nature Reserve of Castanopsis kawakamii in Sanming City, Fujian province were investigated. The results showed that the community is composed of 223 species belonging to 159 genera of 80 families of vascular plants, accounting for 80.5 percent of the genera containing only single species. The geographical composition of the flora is complex, which comprises 12 of 15 distribution types of Chinese seed-plants, the tropical and sub-tropical components are dominating over the whole vascular plants, the pantropical distribution genus is in the majority of genera, followed by the tropical Asia one. There also exists some temperate-originated species. The descending order of the magnitude of species diversity was shrub layer, tree layer, herb layer. The evaluation on distribution types and species diversity of the community showed that this forest is a transitional type from south-subtropical forest to mid-subtropical evergreen broad-leaved forest.

Effect of Terrain on Growth and Trunk's Basic Volume Weight of Alnus cremastogyne from Plantation LIAN Hua-sen 2005, 34(03): 23-26.  Abstract ( )   PDF (261KB) ( )   An orthoganal design with four terrain factors under two levels was carried out to systematically analyze the law of variation on diameter, height and trunk's basic volume weight of 13-year-old Alnus cremastogyne from plantation. The results showed that slope form was the most important factor which influenced diameter, height and trunk's basic volume weight of Alnus cremastogyne from plantation and the slope with less than 45 degree influenced the diameter and height insignificantly. As to diameter growth and trunk's basic volume weight, slope aspect is the second important influencing factor and position on the slope is the third one; as to height growth, position on the slope is the second important influencing factor and followed by the slope aspect.

Vegetative Character and Quality of Two Garden Lycium chinense Varieties SUN Hong 2005, 34(03): 27-29.  Abstract ( )   PDF (164KB) ( )   The vegetative character, nutritional composition and eating quality of two garden varieties (‘Da Ye’ and ‘Xiao Ye’) of Lycium chinense were studied. The results showed that ‘Da Ye’ was sensitive to low temperature and ‘Xiao Ye’ was sensitive to high temperature, and the average yield of young buds of ‘Da Ye’ was higher than that of ‘Xiao Ye’. The contents of protein and Vit C in young buds of ‘Xiao Ye’ were higher than those of ‘Da Ye’. It is suggested that growing these two varieties in due proportions can increase the unit yield.

Effects of Substrate,Nutrient Solution and Chemical Agents on Growth and Flowering of Anthurium andraeanum SHENG Ai-wu, HE Quan, ZHAO Yin-fang, ZHANG Wan-feng 2005, 34(03): 34-36,33.  Abstract ( )   PDF (266KB) ( )   Effects of three substrates (peat:perlite:sand=1:1:1, perlite and water) and three nutrient solutions (N:P2O5:K2O=3.387:1:5.661, 6:1:8 and 4:1:8) on the growth of Anthurium andraeanum were studied. The results showed that nutrient solution of N:P2O5:K2O=4:1:8 was the best for the height, weight and leaf number of the plant when cultured in water. Under the heat stress (32℃), water substrate could significantly reduce the leaf yellowing of Anthurium andraeanum. Meanwhile, 6-BA could significantly decrease the number of yellow leaves when cultured in the substrate of peat:perlite:sand=1:1:1. Related Articles | Metrics
