西双版纳橡胶,胡椒,咖啡根际真菌及细菌区系的研究

研究西双版纳橡胶、胡椒、咖啡根际土壤中的真菌和细菌。从橡胶土样得真菌１１属４８株，其中青霉属（Ｐｅｎｉｃｉｉｔｉｌｌｉｕｎｍ）２９株，占绝对优势；细菌１４属６１株，其中芽孢杆菌属（Ｂａ－ｃｉｌｌｕｓ）３５株，占绝对优势。从胡椒土样得真菌１０属２５株，其中青霉属６株，为优势菌之一；细菌９属６１株，芽孢杆菌４２株，居绝对优势。从咖啡上样得真菌５属２３株，仍以青霉属居绝对优势，占１７株；细菌１２属６４株，芽孢杆菌有３５株，为优势菌。在初步探讨了三种经济作物根际真菌及细菌区系的组成、数量及优势种群的基础上，还分析了这些微生物在根际土壤中的作用及部分真菌病害问题。     

The most important lacewing species in Indian agricultural crops,Chrysoperla sillemi (Esben-Petersen), is a subspecies of Chrysoperla zastrowi (Esben-Petersen) (Neuroptera: Chrysopidae)

The existence is reported of rhizoids in specimens of Bowerbankia pustulosa and Bowerbankia citrina collected from different Iberian locations. The structure of these rhizoids differs from that of other fixation structures previously reported in Bowerbankia and redescribed here. Rhizoids in both species are probably homologous with those of Amathia, supporting the close relationship between these two genera.     

零上低温对巴西橡胶树,小粒种咖啡线粒体结构功能的影响

在人工零上低温下,巴西橡胶树、小粒种咖啡线粒体超微结构受损伤,其程度与抗冷性呈负相关;呼吸强度和细胞色素氧化酶同工酶谱带的变化,在不同作物、不同抗性品系中存在差异;ATP含量随着低温持续时间而下降,抗性弱的品系下降得较快。
