Demonstrative Experiment of Balanced Fertilization for Mature Trees of Longan Zhuang Yimei, Wang Renji, Xie Zhinan, Xu Wenbao, Huang Zhenliang, Chen Meiyuan 1997, 26(01): 1-5.  Abstract ( )   PDF (295KB) ( )   The demonstrative experiment was carried out in south Fujian during 1992~1996 in order to find out the feasibility of the balanced fertilization at full bearing period of longan trees. The results indicated that the balance fertilization of mature longan orchards markedly increased the soil fertility, maintained the suitable status of the plant nutrition and increased the fruit yield. The maintenance of a yield level of 1000 Kg longan fruits per 667 m2 growing on the red soil hilly lands of south Fujian could refer to the following fertilization program, namely, N, 20~25 Kg (N of organic fertilizer making up 40 percent of the total N fertilizer); N:P2O5:K2O:CaO:MgO=1.0:0.5~0.6:1.0~1.1:0.8:0.4.

Effects of Calcium on Peroxidase, Respiratory Rate and Ethylene Production in Postharvest Litchi Fruits You Ruichen, Chen Chun, Lin Lirong, Liu Hongzhou, Huang Weinan 1997, 26(01): 6-10.  Abstract ( )   PDF (284KB) ( )   Litchi fruits were treated with calcium at postharvest period. An appropriate higher level of calcium in postharvest fruits reduced peroxidase activity, respiratory rate and ethylene production and thus delayed the decayed fruits. Related Articles | Metrics

Ion Adsorptive Behaviour of the High Water Absorbent Resins Lin Jie, Liu Hongzhou, Chen Chun, You Ruichen 1997, 26(01): 11-15.  Abstract ( )   PDF (335KB) ( )   In this paper the ion adsorptive behaviour of the high water absorbent resins is reported and the mechanism of the adsorption is discussed. The resins are similar to cation-exchange polymers. Their cation-adsorption power is stronger and the anion-adsorption power is lower. The adsorptive power of the resins varied with cations and their concentrations. Related Articles | Metrics

A Comparative Analysis of the Colour Change at Postharvest of “Zihua” and “Guixiang” Mangoes Jiang Yueming 1997, 26(01): 16-19.  Abstract ( )   PDF (246KB) ( )   A comparative analysis of the colour change was carried out at postharvest of "Zihua" and "Guixiang" mangoes. The content of chlorophyll decreased and carotenoid increased gradually as fruit ripened. Compared with "Guixiang", the lower content of chlorophyll and higher level of H2O2 in "Zihua" mango were found, which was associated with the colour change of "Zihua" fruit. Treating the fruits with ethylene or H2O2 markedly accelerated the degradation of chlorophyll, resulting in yellow appearance of "Zihua" mango. However, it had little effect on the colour change of "Guixiang" mango.It suggests that the colour change of "Guixiang" mango is associated with the degradation of chlorophyll and the action of H2O2, and other factors are involved.

Investigation on Plant Nematodes Associated with the Ornamental Plants Chen ChengJin, Zhang Shuanghong, ZhangRenfa, Ye Xinmin, Liu Kailiang, Lin Xiaoli 1997, 26(01): 20-24,48.  Abstract ( )   PDF (398KB) ( )   Ten genera of plant nematodcs, i. e. Aphelenchoide, Aphelenchus, Helicotylenchus, Hemicriconemoides, Meloidogyne. Paratylenchus, Rotylenchus, Tylenchorhynchus. Tylenchus and Xiphinema were identified from the rhizosphere soil of 24 species of ornamental plants. There were more complicated population structures and higher population level in the rhizosphere of wood-plants and perennial herbaceous plants. Related Articles | Metrics

Ultrastructure of Supernodulating Soybean Nodule Zhang Ning, Huang Weinan 1997, 26(01): 25-28,49.  Abstract ( )   PDF (341KB) ( )   The electron-microscopic observation indicated that the uninfected cell of supernodulating soybean had an obviously enlarged nucleus. The younger bacteroid was elliptic and had a similar nucleus region in cell. The normal bacteroid had an intact membrane envelope and PHB granules. There appeared similar abnormal phenomena of ineffective nodule in infected host cell. which few bacteroids degenerated and were lytic, and there were empty membrane envelopes and bare bacteroids. The decrease of nitrogenase activity in supernodulating soybean might result from above-mentioned abnormal phenomena. Related Articles | Metrics

The Ultrastructure of Leaf Cells in Albino Seedlings of Cycas revoluta Fu Ruishu, Lu Jian 1997, 26(01): 29-31,50.  Abstract ( )   PDF (259KB) ( )   This paper is the second part of a serial reports on albino seedling of Cycas revoluta. The ultrastructure of leaf cells in albino secdlings of Cycas revoluta was observed by ultrathin-section and electron microscopy techniques. The results showed that there were distinct differences between ultrastructure of the leaf cells in albino seedlings and that in the normal seedlings of Cycas revoluta. The cytoplasma amount of the albino seedling leaf cells was few. No normal chloroplast-like menbranes and degenerative mitochondria were observed in the albino seedling leaf cells.

A New Method for Nitrogen Determination in Citrus Nutrient Deficiency Diagnosis Qiu Shan, Qiu Xingchu 1997, 26(01): 32-34.  Abstract ( )   PDF (170KB) ( )   The Conditions and method for determining nitrogen in citrus leaves with Qiu's nitrogen extractor were studied. The results showed that the method was simpler, safer and more accurate compared with distillating method. Furthermore, about 90% electricity was saved by this method. Related Articles | Metrics

The Biology and Conservation of Glyptostrobus pensilis Han Lijuan, Hu Yuxi, Lin Jinxing, Wang Xianpu 1997, 26(01): 43-47.  Abstract ( )   PDF (432KB) ( )   This paper summarizes the earlier works on the biological features of Glyptostrobus pensilis, including morphological character, internal structure of shoot apex, leaf, bark and wood, pollen and chromosome, development of male and female gametophyte, and embryo. Moreover, the geological distribution, ecological and phytocoenological characteristics are outlined. The reasons for making the plant to the threatend state are preliminarily analysed and effective measures of conservation are put forword as well. Related Articles | Metrics
