The relationships between root length of Salsola implica, Halocnemum strobilaceum and Kalidium foliatum seedlings and soil salt concentration are significant, but the relationship between the number of lateral roots of Suaeda linifolia seedlings is significantly negative, the tall, fresh weigh and the number of leaves of Suaeda linifolia and Salsola implicata are almost normal distribution in the range of soil salt concentration, the optimum salt concentration is 0.27-0.89% and 0.16-0.36% respectively; The growth of Halocnemum strobilaceum and Kalidium foliatum seedlings are poor in high salt soil.

亚麻叶碱蓬幼苗侧根数与土壤含盐量呈显著负相关，密枝猪毛菜幼苗根长与土壤含盐量相关显著，而亚麻叶碱蓬和密枝猪毛菜幼苗的株高、鲜重和叶数在土壤一定含盐范围内呈近似正态分布，其最适盐度值分别在0.27%－0.89%和0.16%－0.36%。

In this experiment, typical ectomycorhizal fungi strains(Lactarius delicious 01, 02 and 03) were isolated from Three-Gorges Reservoir where Pinus Massoniana was very popular. And Suillus placidu 504(sp 504) and Laccaria bicolor S238N (Lb 23 8N) typical in South China were also chosen to study the effects of ectomycorrhizal fungi on the growth and nutrient absorption of Pinus Massoniana. And the culture characteristics of three strains of Lactarius delicious were also studied. The object of this study is to supply techniques in culturing ectomycorrhizal seedlings for planting trees in Three-Gorges Reservoir.

试验从马尾松大面积分布的三峡库区，分离出代表当地生态条件的松乳菇(Lactarius deliciosus 1、2和3)，并选择中国南方具有代表性的华南牛肝菌(Suillus placidu 504)和双色蜡蘑(Laccaria bicolor Lb S238N)，研究了松乳菇3个菌株的培养特性，并利用Lb S238N、Sp 504、Ld01和Ld03苗床接种马尾松，观察了它们对幼苗的生长和养分吸收的影响，目的是为三峡库区马尾松的植树造林提供培育菌根化苗木技术。

Cell line transformed with A〓 in Medicago sativa could not regenerate.

利用发根农杆菌A〓和LBA9402Bin19两个菌株对苜蓿和红豆草不同外植体进行了转化。

Experimental use of the separation of the organization, from 16 kinds of medicinal plants isolated from the roots of Health within 11 mycorrhizal fungi.

本实验利用组织分离的方法，从常见的16种药用植物的根部分离得到了11株内生菌根真菌。

But for Myriophyllum spicatum, the optimal concentration of phosphorus was 0.4 mg·L-1. At 0.2 mg·L-1phosphorus, the height and root-length of Hydrilla Verticillata was greater than that of Myriophyllum spicatum, while at 0.4 mg·L-1 phosphorus the reverse was true.

两种沉水植物株高和根长增加量在磷质量浓度小于0.2 mg·L-1时，表现为轮叶黑藻大于穗花狐尾藻；当磷质量浓度大于0.4 mg·L-1时，表现为穗花狐尾藻大于轮叶黑藻。

The representative strain SDW018 of group Ⅲ nodulated Phaseolus vulgaris, Vigna unguiculata, Glycine max, Leucaena leucocephala, Medicago sativa, Lotus corniculatus. The other tested strains nodulated 1 to 3 leguminous plant species respectively.

群Ⅲ的代表菌株SDW018可与菜豆、豇豆、大豆、银合欢、紫花苜蓿、百脉根等结瘤。

Results showed that the seed germination rate,emerged seedling rate and survival seedling rate of Platanus aceriflia Willd.decreased with dose increase at the dose of 50～400Gy,as well as the plant height,fresh weight and length of root.

结果表明，在50~400Gy辐射范围内，随着剂量的增加，悬铃木种子的萌发率、出苗率、成苗率降低，株高、鲜重、根长也明显下降。

This may be mostly resulted from the smaller lateral root diameter and the nearer distance between clonal ramet and mother plant or related to the environmental conditions of different population patches or different management measures.

可能是产生克隆分株的根径较小和克隆分株距离母体植株较远造成的，同时也可能与不同种群斑块环境条件的差异或不同的管理措施有关。

They although cut went out to go up sinuately hill alley, but on the road if encounter an a Qing Teng, oak that prick a leaf, or one individual plant is called intimately by them the plant of the smoke tree and so on of " daughter red ", their would rather lowers his head to bow, sideways detour and over-, the life that also wants these green gives way, do not make they suffer any kill cut down and trample.

他们虽然开凿出了弯弯曲曲的上山小路，但路上假如遇见一根青藤、一棵刺叶栎，或者一株被他们亲昵地称为&女儿红&的黄栌之类的植物，他们宁肯低头弯腰、侧身绕路而过，也要给这些绿色的生命让路，不使它们遭到任何戕伐和践踏。
