伸长

Results showed that the elongation of mesocotyl and internode of coleoptile played important roles in the seedling emergence of the weedy rice from northern China.

研究结果表明，在中国北方发现的部分杂草稻具有较强的中胚轴伸长特性和芽鞘节间伸长特性。

The inhibition of coleoptile elongation is alleviated when exogenous auxin was added to the medium under the low concentrations of Cu2+ stress. However, under high concentrations of Cu2+ stress, as the toxicity is so much, exogenous auxin is not available any further.

小麦胚芽鞘的生长只表现为细胞的伸长，原理为生长素作用的结果，外加生长素，发现生长素缓解了重金属铜对胚芽鞘伸长作用的抑制，而在高浓度时，由于毒害太大，所以无效。

So worked resistance decrease of grafted cucumber.Grafted cucumber and squash root exudates have the inhibitory effect of germination of cucumber, elongation of root and hypocotyls, and have the same effect on squash.

南瓜和嫁接黄瓜根系分泌物对黄瓜发芽率，胚根胚轴的伸长均具有明显的抑制作用，这种抑制效果与浓度呈正相关；对南瓜发芽率及其胚根胚轴伸长的抑制也达到显著水平，这种抑制效果与浓度同样呈正相关。

The best method for extracting solube proteins from leaves was selected for polyacrylamide gel was established.The result showed that there exists two decrescendo protein bands with 76.3 X 103 and 64.1 X 103 during the livelong stage. It presents two new protein bands with 47.3 X 103 and 41.4 X 103 in adventitious roots differentiating and elongation stage.

研究结果表明，在组培叶片不定根的发生过程中，从诱导阶段到根原基形成阶段和不定根分化伸长阶段存在两个逐渐减弱的蛋白谱带：76.3×10~3和64.1×10~3，在不定根分化伸长阶段出现了两条新的蛋白差异谱带：47.3×10~3蛋白和41.4×10~3蛋白。

The gene eui is one of the most important genes deployed in hybrid rice breeding, since it has been used to improve panicle exsertion of rice male-sterile lines.

水稻eui2突变体是通过诱变方法获得的，其表型特征是在抽穗期穗颈节间剧烈伸长，其伸长部位仅限于穗颈节间，而eui1突变体除了穗颈节间伸长外，其它各个节间也都显著伸长。

It is showed that the increase of tire body glue extension module and the decrease of bead glue extension module can improve the performance.

分析结果表明，增加子口胶，胎体层胶的定伸长模量和减小圈垫胶的定伸长模量可改善子口包布反包末端性能。

The conversion boundary of self-incompatibility was researched by sowing by stage. Sunshine of day and temperature was studied critically by investigating leafage and researching traits indoors. The results showed that the daily minimum temperature was the principal factor of affinity conversion and the affinity conversion boundary was 16.5~18.1℃.HE97 was primarily regard as self-incompatible line in this research. The method was by inbreeding and sib HE97, Half the silk of HE97 and Zheng58. Inbreeding and cross have been done simultaneously. The extending condition of pollen tube was observed by dying the silk after pollinating 4 hours. The individuals with pollen tube were observed having seeds, while the individuals without pollen tube were observed having few seeds or no seeds. So this study regard HE97 as sporophytic self-incompatibility .The planting ration of female parent HE97 and male parent 87-1 was 4:1.The nature cross-pollination was studied by the theory of endosperm xenity, the study show that the setting percentage of HE97 was 625%, in which the seed in self was 70% and the seed in hybrid was 30%. This was consistent with the study of silk anatomy structure, then come to the same conclusion: compatible pollen germination and fertilization can stimulate the self-incompatible pollen germination and fertilization in the same corn cob.

通过分期播种，进行了光温敏自交不亲和材料HE97亲和性转换区间的研究，依据田间跟踪调查叶龄及室内考种研究了HE97亲和性转换区间的光温临界值，结果表明：1日最低温度是影响HE97自交不亲和性的主要原因，亲和性转换区间在16.5℃～18.1℃之间。2通过HE97自交和姊妹交以及将HE97与郑58作为双亲，各自的花丝一分为二，分别正反交，授粉后4个小时分别取其花丝进行固定、染色，观察花粉管的伸长情况，根据结实率与花粉管伸长的对应关系，结果发现观察到花粉管的对应植株收获到了种子，而没有观察到花粉管的对应植株结实率极低或没有结实，本研究把HE97初步划为孢子体自交不亲和类型。3以HE97为母本，87-1为父本，按4母：1父行比，通过花粉直感效应研究天然异交率，结果母本HE97结实良好(62%)，其中自交粒占70%，异交粒占30%，结合花丝切片观察表明，亲和花粉的萌发及受精会导致落在同一果穗柱头上不亲和花粉的萌发不再受抑制。

The eco-toxicity of Cu, Zn, Pb, and Cd in the single form was tested with four types of soils( red loam soils, meadow brown soils, chestnut soils, and dark brown soik) and their combined effect was determined with meadow brown soils.

测定了4种土壤(红壤、草甸棕壤、暗棕壤和栗钙土)条件下，Cu、Zn、Pb和Cd单一污染对小麦种子发芽与根伸长抑制率及其复合污染效应结果表明，同一浓度下，重金属对小麦根伸长抑制率均明显大于对种子发芽抑制率。

The litter of little black cats were sleeping on the oilcloth, nestled against their mother's belly, and the latter was stretching her paws out in a state of beatitude while the big tortoise-shell cat sat at the other end of the table, her tail stretched out behind her and her yellow eyes solemnly following the flight of the women.

那一窝小黑猫贴着母猫的肚子睡在漆布上，母猫怡然自得，伸长爪子，而那只大红公猫则坐在桌子的另一头，伸长尾巴，用黄眼睛看着那些逃走的女人。

The timetable of axillary bud germination and bolting varied withvarieties.The former prior to the later in Xuzhou White and Boltless,but the opposite inErshuizao and Taicang White.

只是不同品种腋芽萌发和薹伸长的先后不同，二水早和太仓白蒜薹伸长早于腋芽萌发，而徐州白蒜和无薹蒜的腋芽萌发较薹伸长早。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
