Abstract:
The cultivated area of "Shanyou 63" has ben kept the first in china since 1986.the average cultivated area one year is 4.67 million hm2, about 22% of the area Of indica zone in China and Particularly, 27.1% in 1990.It is almost cultivated all over the indica cultivated zone 17°36’N to 37°49’N and from 100°36’E to 121°38’E to 121 °56’E.It has been cultivated 52.67 million hm2 and increased by about 58.5 billion kg grain from the year 1986 to 1995.According to the national rational yield trial,it increased 1.1 t grain per hm2 comparing with CK.General grain yield was 8.25t to gi Per hm2 and the highest was 13.9t per hm2.It has good ratoon ability and the highest grain yield of ratoon rice reached 8.77t per hm2.This paper introduces the main agronomic and biological traits of "Shanyou 63".The yield traits ie.panicles /hm2, grains per ear, and grain weight are all higher and well coordinated.The light compensation point is lower, and the light saturation point, utilization efficiency of light energy and N and K in the soil are higher than CK.It is tolerant to saline-alkali soil, to high temperature at florescence, and resistant to blast.It has good eating and cooking quility and ratoon ability.The ratoon rice yield reaches 8.23t per hm2.

Abstract:
The endogenous hormone IAA and GA1+3+4+7 in young panicles and the backward second leave sheathes of rice male-sterile line with alloplasm-homokaryon WAV41 A and KV41 A and their maintainer V41B were determined by ELISA (enzyme linked immunosorbent assay).The results showed that the contents of IAA and GA1+3+4+7 in young Panicle of WAV41A and KV41A ware less than that of V41B during the period when young Panicle developed, it was suggested that male bole related to the loss of endogenous hormone (esp.IAA); the contents of IAA and GA1+3+4+7 in WAV41A was less than that of KVV41A, and the line of the two endogenous hormone in WAV41A was earlier than that of KVV41A;the contents of IAA and GA1+3+4+7 was higher.than that of KVV41A and V41 B; the Physiological metabolic of KVV41A was similar to that of V41B, it was suggested that there were significant difference in the metabolic of endogenous hormone between WAV41A and KVV41A.

Abstract:
Microbial contamination and browning were the main reason causing the low survival rate of longan tissue culture in vitro.Using the internal tissue of middle stem sections and alternately immersed with multiple disinfectants as pretreatment can decrease contamination and browning.The stem germination numbers varied with seasons, and the stems in summer or autumn was suitable as explants.The rate of responsive explants could reach 73% when they were culture on MS media, and the adventitious stem grew very well.

Abstract:
Base rot disease of passionfruit is a destructive disease in passionfruit ,The results showed the Pathogen was Fusarium oxysporum Schl.f,sp.passiflorae.The disease develops from Mar.to Dec.in the year.The relationship between the disease development and cultivars, age of tree, pH value of the soil.and support form was also discussed respectively.The experiments showed that Thiophanate methyl 70Wp Could control the disease effectively.

Abstract:
The life history of Cheyletus Malaccensis oudms was reported in this paper.It consists of egg stage, larve stage, Protonymphal stage, deutonymphal stage and adult.The mites were reared in separately small special cell at 18-26℃.The whole life history requires 48-50 d.Each mite eats about 10-12 preys/d and five hundreds preys in its whole life history.Unchanged the numbers of preys, the preing capacity decreased with C.malaccensis oudms density increased.The model was A =16.5462P-0.5725 (r=0.96).The model of oviferous number of predator to prey density was Y=6.65 +5.64X (r = 0.96).The model of the relationship of systematic number between C.malaccensis and L.destructor was:dN/dt=N(0.76+0. 62P) and dP/dt=P(-0.50-0.11N).

Abstract:
Plasma VLDL content had genetic speaciality in different duck specs.The female duck VLDL content during laving pened was 4.48-17.65 times higher than that of male duck.The higher egg-laying rate the female duck had, the higher content and lower coefficient of variability the plasma VLDL was.There were active Correlations between VLDL content with body weigh and fat rate,and negative correlation with lean rate in 7-week-old meat duck.

Abstract:
According to the field level Oo nonfertilization treatments from 89 N.P.K fertilizer trials on rice, the paddy soil was divided into 5 fertility grades in Fujian.In the same soil fertility grace, the regional fetilizer response models were established by the average yield of the same treatment in different sites.Based on the regional fertilizer response models that was the typical model or non-typical mode, the optimum fertilizer application rate in different soil fertility grades were recommended by the marginal yield method and yield freguency analysis method respetively.The thirty-two test and verify trials showed that the rice optimum fertilizer application rate in different fertility grades may increase 405-600kg/hm2 rice yield and 352-399 yuan/hm2 net income more than fanner’s practice in average.

Abstract:
Recombinant PUC inserted with full length nucleic acid sequence of chrysanthemum stunt viroid was used as template DNA to prepare digoxigenin-labelled and biotin-labelled probes with two universal primers by polymerase chain reaction.These two Probes were used to detect Samples infected with CSV.The result showed strong positive signals, while the control of the healthy ones gave negative reaction.Absorbance of digoxigenin-labelled probe was higher than that of biotin-labelled Probe for detecting CSV cDNA with PCR-microplate hybridization.The sensitivity of the digoxigenin-fataled probe for detecting the CSV RNA by dot blot method was 50fg, while that of the biotin-labelled Probe for detectingthe CSV RNA was 5pg.
