Nov.. The main symptoms of the bacterial disease on Vigna angularis were canker of stalk.The strains were straight or curved rods; polar flagellum one; Gram-negative; could infect Vigna angularis、 Glycine max、 Vigna radata、 Vigna umbellate、 Phaseolus vulgaris、 Pisum sativum、 Pisum sativum var.humlie; oxidase negative; nitrate reduction negative; 5% glucose agar mucilage positive; esculin hydrolysis positive; starch negative; milk hydrolysis positive; H_2S positive; acid from L-arabinose, D-mannose, D-galactose, cellobiose, trehalose and fructose; 5%NaCl positive; G+Cmol%-69%.

红小豆溃疡病主要症状为茎部溃疡；各菌株菌体均杆状；极生鞭毛1根；革兰氏染色阴性；人工接种能侵染多种豆科植物；好氧；氧化酶阴性；硝酸盐反应阴性；5％葡萄糖营养琼脂黏液生长阳性；七叶灵水解阳性；淀粉水解阴性；牛奶分解产碱；产生硫化氢；能从阿拉伯糖等产酸；最大耐盐量为5％；G+Cmol％为69％等特征，根据《手册》9th ed相关部分，确定该病由野油菜黄单胞菌苜蓿致病变种Xanthomonas campestris pv.alfalfae(Riker，Jones et Davis 1935)Dye 19781引起。

In the more highly differentiated Phaeophyta brown algae , such as wracks and kelps , the stalk between the holdfast and the blade .

The leaves, leafstalk, and stems from grapes were used as explants to induce calli and subculture in medium (100 mL B5 medium containing 3 g sucrose and 0.6 g agar) with different plant hormone combinations (6-BA, KT, IBA, 2, 4-D), and then the resveratol content from those calli was determinated by using HPLC.

以葡萄的叶、叶柄和茎分别作为外植体，在不同激素组合（6-卞氨基嘌呤(6-BA)、激动素、吲哚丁酸、2，4-二氯苯氧乙酸(2，4-D)）的培养基（以B5培养基为基本培养基，含30g/L蔗糖和6g/L琼脂）上，进行愈伤组织的诱导和继代培养，并利用高效液相色谱法对不同来源愈伤组织中的白藜芦醇含量进行测定。

About calli from different explants, there were significant differences in their resveratol content, and their medium of the highest content expressed were respectively: for leaves, B5 medium+6-BA 0.5 mg/L+IBA 0.2 mg/L; for leafstalk, B5 medium+6-BA 1.0 mg/L+IBA 0.2 mg/L; for stems, B5 medium+6-BA 0.5 mg/L+IBA 0.2 mg/L.

以叶、叶柄和茎为外植体诱导愈伤组织时，其白藜芦醇含量最高的培养基分别为B5培养基+6-BA0.5mg/L+IBA0.2mg/L、B5培养基+6-BA1.0mg/L+IBA0.2mg/L和B5培养基+6-BA0.5mg/L+IBA0.2mg/L。

More taxol is synthesized in the callus of young stem and leaf than inthe callus of others.

在5种外植体中，嫩茎和叶愈伤组织合成紫杉醇的能力较其它愈伤组织强。

The effect of 2,4-Dand 6-BA(6-benzyl aminopurine)at different concentration with MS medium on inducement and differentiation of wild and leaf-thin Z.tenuifolia Willd.'s stolon was studied.

以野生的细叶结缕草的匍匐茎为外植体，MS为基本培养基，研究2，4-D和BA及2，4-D和IAA不同浓度组合对其愈伤组织诱导与分化的影响。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
