Host alterations of the root aphid, Tetraneura nigriabdominalis, among four host plants ( Eleusine indica , Oryza sativa , Zea mays , and Sorghum bicolor ) were studied by comparing adult longevity, fecundity, and population parameters in the laboratory.

於实验室中，研究粗长毛禾根绵蚜 Tetraneura nigriabdominalis (Sasaki 在四种寄主植物(牛筋草 Eleusine indica 、水稻 Oryza sativa 、玉米 Zea mays 及高粱 Sorghum bicolor )转移对其成蚜寿命、繁殖率及族群介量之影响。

Research on the characteristics of ammonium, nitrate and organic nitrogen utilization by ericoid mycorrhizal fungi and impacts on growth in vitro of Rhododendron fortunei was carried out to determine the suitable nitrogen sources in ericoid mycorrhizal fungal cultivation and test the effects of ERM on host plant growth in substrate with different nitrogen sources.

研究从云锦杜鹃根系分离的欧石南菌根(eriocoid mycorrhiza， ERM)真菌对铵态氮、硝态氮和无机氮吸收特性及其接种效应，检测ERM菌株吸收利用不同氮源能力及筛选培养菌株适宜的氮源，并分析ERM对寄主植物氮源吸收的影响。

Plants of aphids include 58 genera in 30 families, among which Gramineae, Moraceae, and Lauraceae have

其次为扁蚜科和斑蚜科；寄主植物中寄生蚜虫类群最多的3个科分别为：禾本科、桑科和樟科。

Besides, The nodulation with else host experiment told us that NWGX035 could nodulate with melilotus suaveolens Ledeb, sophora alopecuroides Linn, lotus corniculatus Linn, sophora viciifolia Hance, trifolium repens Linn. The property of powerful salt, alkali, high temperature endurance and wide nodulation could confirm this strain was a particular strain. The nodulation mechanism and endurance of salt, alkali and high temperature mechanism need to be studied further.

另外，回接其它寄主植物的试验表明， NWGX035能与草木樨、黄化苦豆子、百脉根、狼牙刺和白三叶共生结瘤，其广泛的共生结瘤范围和强的耐盐、碱和抗高温特性可以证明该菌株为一株性状优良的菌株，其共生结瘤机制和耐盐碱机制需进一步研究。
