黄瓜

The best temperature compages to distinguish pollen viability of different varieties was 9℃/ 12℃.

区别黄瓜不同品种低温下花粉活力的适宜温度组合为9℃/12℃。

0Mg/L 6-benzylaminopurine was the optimal concentration of shoots quantity inducing which frequency of inducing shoots and number of shoots per explant were 100% and 11.1 respectively. 0.5mg/L 6-benzylaminopurine was the optimal concentration of shoots length inducing which average length of shoots was 12.0mm. Explant size had significantly effects on direct shoots quantity and length induction. When complete cotyledon used as explant, frequency of inducing shoots, number of shoots per explant and average length of shoots could approach to 100%, 6.7 and 17.1mm respectively. 2.0mg/L silver nitrate could significantly increase shoot quantity induction, both frequency of inducing shoots and number of shoots per explant could be as high as 97.2% and 4.2 respectively. But silver nitrate also could restrain shoots elongation.

结果表明：不同黄瓜品种直接不定芽数量诱导存在显著差异，但长度诱导无显著差异；6-苄氨基嘌呤对直接不定芽数量和长度的诱导作用显著，其中4.0mg/L为数量诱导适宜浓度，其出芽率和每外植体出芽数达到最高，分别为100.0%和11.1，0.5mg/L为长度诱导适宜浓度，其平均芽长12.0mm；外植体的大小对直接不定芽数量和长度均具显著影响，随着子叶的增大诱导直接不定芽的数量和长度增加，其中单片完整子叶为最适宜大小，其出芽率、每外植体出芽数和平均芽长分别达到100%、6.7和17.1mm；硝酸银也对直接不定芽数量诱导影响显著，其中2.0mg/L为适宜浓度，出芽率和每外植体出芽数分别达到97.2%和4.2，但对芽长有抑制作用。

METHOD Thirty four species of 80% ethanol plant extracts stored for six months were tested against C. lagenarium by using growth rate and WA flat germination. The inhibitory rate of 11 PE against conidium germination of C.

选用34种植物的80%乙醇提取物（储藏期为6个月），采用生长速率法和水洋菜平板表面萌发法，测试其对黄瓜炭疽病菌的抑制作用。

My mother often cooks cucumbers for me .

我的妈妈经常烧黄瓜给我吃。

She sashayed up to my desk cowl as a cucumber.

她滑步行至我的书桌，像黄瓜一样的罩。

I like cucumbers, yellow croaker.

And the relationship between sex of cucmber and isozyme were analysed. The results indicated that, in terms of numbers of band and activities of peroxidase and superoxide dismutase were significantly induced after treated with silver nitrate and ethephon at 300mg/L and 200 mg/L in cucumber leaves, respectively.

研究表明，300mg·L〓硝酸银和200mg·L〓乙烯利处理黄瓜茎尖后，叶片中过氧化物酶和超氧化物歧化酶两种同工酶的酶谱带数和酶活性均明显受到诱导，而过氧化氢酶几乎不受影响。

The absorption of root system was the main sources of nitrogen in the plant.The effects of matrix ventilation on the abaorption,transportion and metabolism of nitrogen in the root system of cucmber were discussed deeply.The results showed that contents of ammonium,nitrate,free amino acids and soluble protein in cucumber roots were higher in G1 treatment.Contents of ammonium,nitrate and free amino acids in cucumber roots were the trend of the dropping after the first rising in F1 treatment,but contents of soluble protein was lower11.03%than that of the control.

根系吸收是植物体内氮素的主要来源，本研究深入探讨了基质通气状况对黄瓜根系氮素吸收、运输和氮代谢的影响，结果表明G1通气处理根系的铵盐、硝酸盐、游离氨基酸和可溶性蛋白含量均较高；非通气处理(F1处理)根系内铵盐、硝酸盐和游离氨基酸含量呈先升高后降低的趋势，而可溶性蛋白含量始终较低，比对照降低11.03%。G1处理根系硝酸还原酶、亚硝酸还原酶、谷草转氨酶、谷丙转氨酶、谷氨酰胺合成酶活性均较高；而F1处理的酶活性在处理末期显著降低，其中谷氨酰胺合成酶活性比对照降低33.33%。

5During chilling stress,Ca~(2+)treatment could delay the decrease of Fm,Fv/Fo, Fv/Fm,Fv"/Fm",ΦPSⅡ,qP,ETR;And it could delay the increase of Fo and qN of the heat-shock-induced cucmber seedings.Then it delay the injury of PSⅡwhich caused by low temperature.

5钙处理能减缓热激黄瓜幼苗冷胁迫下Fm、Fv/Fo、Fv/Fm、Fv′/Fm′、φPSⅡ、qP、ETR的下降和Fo、qN的上升，从而缓解了低温对PSⅡ的损伤；而EGTA处理则相反。

4During chilling stress,Ca~(2+)treatment could delay the decrease of chlorophyll content and RuBPCase activity;And it could enhance Pn,Gs,Tr,the saturation point and dark respiratory speed of the heat-shock-induced cucmber seedings.So it reduced Ci.But the EGTA treatment had the opposite effect.

4钙处理能减缓热激黄瓜幼苗冷胁迫下叶绿素含量和RuBPCase活性下降，提高Pn、Gs、Tr、光补偿点和暗呼吸速率，降低Ci；而EGTA处理则相反。
