Abstract:在筛选和鉴定水稻T-DNA（Ds）插入纯合体的过程中，观察到1个叶片卷曲的突变体．对该突变体进行遗传分析表明，分离群体出现叶片卷曲和叶片正常2种植株类型，其分离比率为3：1，符合1对基因的显性遗传．Basta抗性检测及PCR分子检测证实，该突变体是由单一T-DNA（Ds）插入所引起的，突变性状与T-DNA（Ds）共分离．该突变材料可用于插入座位的基因克隆．

Abstract:Based on soil moisture distribution under sprinkler irrigation,the root growth and distribution of winter wheat under different irrigation conditions were studied.The results show that sprinkling irrigation is more useful for the plant's growing and can also increase the efficient utilization of water.Under sprinkling irrigation,the root of the plant concentrates on the upper soil and tends to move up.Both of jointing stage and ripening stage, the maximum of root length density apprears on the 20 cm layer and root length density decreases with the increases of the depth under 20 cm.The root's death rate is different under different water treatments.The death of the root is mainly occured on the surface of soil.When analyzing the root dry mass of different layers of the three treatments in jointing and ripening stages,the difference isn't significant.

Abstract:Effect of the different drought stress on the aromatic constituents and relative contents in the fresh leaves of Lingtou Dancong tea plants was studied in this paper.Results showed that drought stress could evidently increase the kinds of aromatic component in fresh leaves.The largest number(58 kinds) of aromatic constituents was found under 10.56%(w) water stress among several treatments,while the fewest number was found under the absolute water content of 19.59%(w).The total amount of relative content of 17 kinds of aromatic constituents as Linalool etc.,increased with drought stress,whereas 12 kinds of aromatic constituents as Tetradecanoic acid etc.,decreased with drought stress.Linalool,Linalool oxide,Etradecane,10-Methylnonadecane,Dodecanal showed highest contents under the absolute water content of 10.56%(w);Cyclohexane,1-Hexadecene,1-Tricosanolonly was induced in the absolute water content of 10.56% and 5.73%(w),while drought stress could inhibit synthesis of 7 kinds of constituents as nonanedioic acid monomehtyl ester,etc.The different drought stress could induce special aromatic constituents.The number of aromatic constituents in fresh leaves increased with drought stress.

Abstract:研究了以污水厂污泥与尿素、磷酸二铵、磷酸铵、氯化钾等化肥为原料的复混肥生产工艺，通过控制C／N、含水率、温度、供气量等工艺参数，生产出了能在农业上应用的污泥复混肥．通过在沙质土壤中施用不同量及不同配方的复混肥，进行了城市生活污水污泥复混肥在冬小麦生长中的应用效果研究．结果表明，污泥复混肥具有良好的改良土壤、增加小麦产量的作用．污泥复混肥作底肥与对照组相比，对植株的生长性状大都产生了显著或极显著的影响．小麦冬前分蘖增加30～60万个／hm^2，返青后分蘖数增加30～90万个／hm^2，拔节期蘖茎数增加30～105万个／hm^2，穗数增加19．5～45万条／hm^2，株高增加2～4cm．施用复混肥对小麦发育生长没有不良影响，有增产效果．一般穗粒数增加1～2个，千粒质量提高0．1～1．7g，产量增加457．5～1209．0kg／hm^2，增产率为7．6％～20．2％．但是由于污泥中重金属在土壤中的累积及在粮食作物中的富集现象，施用复混肥应控制污泥的比例．

Abstract:A pot experiment with tomato cv.Hongbaoshi grown on perlite and soil receiving liquid steeped chicken manure and liquid steeped peanut cake applied through drip irrigation system was conducted to find out the feasibility of this new application method of the two manures.As compared with tomato specific nutrient solution,under perlite culture,fruit yield of liquid chicken manure and peanut cake treatments was only 64.5% and 82.9% of that of nutrient solution,respectively.Under soil culture,fruit yield of liquid chicken manure and peanut cake treatments was 147.0% and 82.8% of that of nutrient solution,respectively.No significant difference of single fruit mass,contents of total soluble solids and titratable acids of fruits was observed among treatments. The dregs was 3.5% when chicken manure was steeped and most of the liquid could be injected into drip irrigation system.However,there was much more dregs(accounting for 74.0%) when peanut cake was steeped which made it unsuitable to be used in drip irrigation system.

Abstract:The differentiation of three haplotypes of Bemisia tabaci populations in China was analyzed using RAPD-PCR in this study.Five B.tabaci populations were collected in the north,middle and south of China,respectively,including three B biotype populations,the indigenous haplotype populations(NaC haplotype) and a new haplotype population from ornamental plants(C_v haplotype).In addition,the greenhouse whitefly,Trialeurodes vaporariorum,was used as a outgroup population in this analysis.The results of the cluster analysis using genetic distances indicated that,first,the population relationship between the NaC haplotype and the C_v haplotype was more close than that between B biotype and NaC haplotype,or that between B biotype and the C_v haplotype;second,the population relationships of the three haplotype of B.tabaci in China was intraspecific,and the C_v haplotype was potentially originated in China or the neighboring countries.

Abstract:The location expansion of the red imported fire ant, Solenopsis invicta Buren,in a special ecology system were investigated and analyzed.The result showed the square area of the infestation was up to(226 hm~2) about 8 years after it was introduced to this area;Expansion distance were as follows: it spread to upper and lower reaches with the distance of(262) and(3 770 m) respectively.Active mounds densities were different among different types of habitat,with field bank>riverbank>roadside>village >riverbed. Average expansion speed of red imported fire ant was(187.9 m/year) in this area.

Abstract:The niche of major predatory arthropod on different resistant rice planthopper in three paddy fields were studied, the results showed that Ulmmeliata insecticepes was the key predator of rice planthopper in early rice. The spatial niche breadth of Dyschiriognatha dentata on resistant variety was the highest while that of Staphylinidae was the highest on susceptible variety. The temporal and temporal-spatial twodimension niche overlap value of predatory arthropod to rice planthopper on medial resistant variety was higher than that on resistant rice planthopper and susceptible variety. The predatory of medial resistant variety was more effective to control rice planthopper.

Abstract:Community component and damage of rice borers were systematically investigated in rice fields in Guangdong Province.The results showed that four major rice stem borers were existed in Guangdong rice fields.They were Scirpophaga incertulas(Walker),Chilo suppressalis(Walker),Chilo auricilia Dudgeon and Sesamia inferens(Walker).Yellow stem borer distributed all over rice grown region in Guangdong Province as reported before and occurred more seriously in Taishan,Nanxiong and Xinhui three counties.It was found that the spread trend of striped stem borer was from northern to southern counties and stalk stem borer distributed all over the rice field in the province except Nanxiong county.The rice loss caused by the rice stem borers was not serious in Guangdong Province because of chemical and cultural control.

Abstract:Two common formulas(Shannon-Wiener index and the reciprocal of Simpson index) were used to calculate the niche breadths among 15 populations of the arborous layer of the secondary forest community in Maofengshan.The niche breadths of most populations were narrow,while few populations were wide,which reflected a simpler community structure.The niche overlaps of 15 main populations were calculated using the niche similarity proportion,which revealed the inter-population niche overlaps and similarities using resources were not higher and the secondary community stayed in a stage of succession.The relationship between the niche overlap and breadth was not obviously correlated.

Abstract:There were flourishing trichomes on the epidermis of Pogostemon cablin's stem and leaf,and they also have distinct difference in shape and development stage.According to the shape of head,the glandular hairs were divided into capitate and peltate glandular hairs.They all occurred very early and their initial cells came from protoderm,which usually originated from the first and second primordium or 1-2 internode of stem.Their developmental process may be divided into four stages,i.e.primitive cell stage,basal cell stage,stalk cell stage and apical cell stage.The origination of non-glandular hairs was later than that of glandular hairs,but lasting origination time in the former was longer than that in the latter.Non-glandular hairs usually started to occur in the secondary immature leaf,and also continue to occur in mature leaves and stems.After initial cells formed,they began to periclinal division to develop into basal cell and head cell.Head cell also began to periclinal division(once or more) to develop into the composing cells of non-glandular hairs.
