Irrigation during over-winter promoted significantly N absorption and accumulation, increased N content in the plants at early stage (before 10, April) and final single stem weight, and reduced stem flowering percentage and florets per cyme, leading to an improved quality of rush stem. With the increased level of N application, N content and accumulation in plants, stem flowering percentage and florets per cyme were significantly increased.

越冬期灌水能显著促进植株对氮的吸收和积累，增加前期（10/4前）植株含氮量和收获期单茎干重，显著减少草茎开花率和平均每花序小花数，从而改善草茎品质；随着施氮水平的提高，植株氮吸收和含氮量相应增加，开花率及平均每花序小花数显著提高。

The influence of oligosaccharides biocide on bacterial colony in the stem of Chinese Cotton 12 was determined by routine separation mathod.The results of two groups experiments indicated that the number of bacterial colonies in the cotton stem,wtich were treated with the oligosaccharides,was lowerthan the control group;and it dropped significantly(8.0×107CFU/g)after treating 10 days,while the control group was 4.2×109CFU/g.This results illustrated that the oligosaccharides biocide could control the cotton damping-off,and as a equaled 0.05,the oriental difference was significant.

通过常规分离方法，测定寡聚糖生物农药对中棉12品种的棉茎体内细菌群落数量的影响。2批实验结果表明喷寡聚糖后棉茎体内细菌群落数量均低于对照，喷寡聚糖10 d后棉茎体内细菌群落数量显著下降(8.0×107CFU/g)，对照4.2×109CFU/g；寡聚糖生物农药对棉花苗期病害的防治效果实验结果表明：寡聚糖生物农药对棉花苗期立枯病有一定的防治效果，且在α=0.05水平差异显著。

In the present experiment, the tender stems of Dracaena cambodiana were used as explants to establish a two-step tissue culture and regeneration system. The effects of types and concentrations of plant hormones on the induction of callus were studied. Based on these, the reactions of callus regeneration to different mutation-induced approaches (60Co irradiation, EMS and colchicines), the regeneration ability of the treated callus as well as the characters diversities (including the appearance traits and cytological observations) of the regeneration plants were investigated.

本试验以龙血树幼嫩茎段为材料，通过对龙血树幼嫩茎段两步培养法再生的研究，建立了龙血树幼嫩茎段离体再生体系，证明了愈伤组织的发生和激素种类与浓度的关系；并在此基础上研究了愈伤组织再生对不同人工诱变方法（60Co辐射、EMS、秋水仙素）的反应、被处理愈伤组织再生能力和再生植株性状多样性、以及再生植株不同生理角度的变异性，得到了2株变异株系。

Add natural disposition, soil helps advance somebody's career to also can survive, the bine does not have thorn, much more ramose, chang Xuan hangs down, young bine is compressed, knaggy, old bine lignification, show a circle a bit; Have a few thorn; Beautiful sheet gives birth to top, have two accrete occasionally, the standard is open, two side are symmetrical, have long canister.

附生性，土壤栽培亦可成活，茎无刺，多分枝，常悬垂，幼茎扁平，多节，老茎木质化，稍呈圆形；有少数刺座；花单生顶端，偶有两朵共生，水平开放，两侧对称，有长筒。

UV-B radiation induced significant changes in the chemical composition of root, stem, and leaf. Under UV-B radiation, the soluble protein, lignin, and fat contents in leaf, lignin content in root, and cellulose and lignin contents in stem were increased, while the starch content in leaf and the soluble sugar, starch, and fat contents in stem were decreased significantly (P.05), compared with the control.

UV-B辐射处理下根、茎、叶部所检测的大多数化学成分与对照相比均有显著变化：叶片中可溶性蛋白、木质素和脂肪，根中木质素，茎中纤维素、木质素含量在辐射处理下显著高于对照；叶片中淀粉，茎中可溶性糖、淀粉和脂肪含量在辐射处理下显著低于对照(P.05)。

The results showed that the seed germination and stem apexes growth of the materials was decreased with the increase of NaCl concentration and PYM concentration and treating time.

结果表明：供试种子的萌发率和茎端组织的存活率随培养基中NaCl浓度的上升急剧下降，平阳霉素处理对茎端组织存活率的抑制明显大于对种子萌发率的影响，平阳霉素处理后存活的种子和茎端组织经NaCl胁迫筛选，筛选出耐NaCl胁迫力明显提高的存活苗，存活苗经无性繁殖，可以保持较高的耐NaCl能力。

The results showed that sugarcane ratoon had the advantages of early emergence and fast growth, early maturing and longer stalk in early grinding season. The low ratoon cane yield was caused by the fewer millable canes and the shorter stalk to comparing with planting cane.

结果表明，宿根甘蔗具有发株早、生长快、成熟早、榨季早期蔗茎较长的优势，指出了宿根甘蔗低产的主要原因首先是有效茎数少，其次是蔗茎较短。

Based on the data and materials collected from many years investigation over the sample plots in Daemonorops margaritae plantation in Daqingshan, Guangxi Province, this paper established a model for its stem length distribution by choosing three growth equations and using a method of twice curve fitting to describe the rule of length distribution for mother stem and sucker stem.

对广西大青山黄藤人工林固定样地进行调查和收集资料，选择Logistic、Weibull和Richards 3种理论生长方程，采用两次曲线拟合法分别描述母茎长和萌茎长结构规律，旨在建立黄藤人工林茎长分布模型。
