The paper reported the studies on relation between content of endogenesis hormoneGA、ABA and stem growth of dentrobiums in huoshan.

本文研究了霍山三种石斛生长期的内源激素GA、ABA的变化与茎高生长的相互关系。

Use this shredding mechanism, the length of the stem is 30 mm theoretically, it has met the ensilage requirements.

使用此切碎装置，玉米茎杆切碎理论长度 30 mm，达到了青贮的要求。

To investigate the toxicity of degraders metabolites, the Microtox test and seed bioassay were measured. The results revealed that not only the toxicity of m-cresol was decreased but also the inhibition for the radical and epicotyl growth of Lactuca sativa were lowered.

降解完毕之代谢物经Microtox生物毒性测试及种子生物分析测试，结果发现接种高效能菌株可明显降低生物毒性，甚至对莴苣种子的胚根及胚茎生长不具抑制效果。

Moutan has two different reproduction ways:obligate seed reproduction and amphitrophic reproduction;the dormitory of its embryo has two stages of epicotyl and hypocotyl;the dormitory could be end if it is treated with two temperature conditions.

Moutan生殖特性，具有根状茎、块根、根出条多种形式的以营养繁殖为主、种子繁殖为辅和专性种子有性生殖的两种类型；胚具有上胚轴、下胚轴两段休眠特性，打破休眠需按一定的程序和两种不同的温度条件；……。

Any of various nonflowering plants of the genus Equisetum,having a jointed,hollow stem and narrow,sometimes much reduced leaves.

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。

The effects of nitrogen application to the content of crude protein,ether extract,crude fiber,ash,nitrogen free extract,amino acids and linoleic acid were different.

施氮量对不同品种茎叶和穗粒中的粗蛋白、粗脂肪、粗纤维、粗灰分、无氮浸出物、氨基酸和亚油酸等品质指标影响不同。

The abnormal forms and the variations of other characters were observed or examined, such as plant short, leaf variations(contain leaf etiolation, leaf notch, leaf roll, and main leaf vein partial nondisjunction, etc.), growing period, cold hardiness, scourge-like caudex differentiation, corm weight increase, and so on.

这些可观察或可检测的变异有形态异常，主要表现为植株矮小及叶片畸形（包括叶片黄化、缺刻、叶卷曲及主叶脉粘连不分离等）；还有其它的性状变化，如生长期、根系、鞭状茎分化、耐寒性，球茎增重和产量等。

Compared with other methods, the effect on preservation of the cut flowers, pretreated in 100 ml/L benzalkonium bromide for 3 hours, was obvious. The fresh flower weights increased slowly, few or none leaves were wilting after transplanted into water for 6 days. Etiolation of the leave slowed down and almost 90% leaves kept fresh after 12 days. The flower buds blooming speed also slowed down, 50% of flower buds were opened, petals were kept fresh, the stems of cut flower were unbent, and none flowers were drooped after 15 days.

与其他预处理相比，在100 ml/L溶液预处理3h，瓶插后鲜重一直呈缓慢上升趋势；6d后，极少数叶片发生萎蔫，叶片黄化速度也很缓慢，约90％的叶片12d后还可以保持新鲜；花蕾开放速度也缓慢，15d后仅有50％的花蕾开花，且花瓣挺阔，无枯萎迹象，而且茎干挺直，不弯颈；保鲜效果明显高于其他的预处理。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
