Lagenarium was higher 60%(for example, Glycyrrhiza yralensis, Lycium barberum and Desmodium styracifolium) as the concentration 0.01g/ml. Especially, the G. yralensis showed the strongest inhibitory effect on it with inhibitory rate of 99.6%. The inhibitory rate of 12 PE against mycelium growth and 15 PE against appressorium formation of C.

供试提取物在质量浓度为0.01 g/ml条件下，甘草、枸杞、金钱草等11种植物的80%乙醇提取物对黄瓜炭疽病菌分生孢子萌发的抑制率大于60%，其中甘草的抑制作用最强，达99.6%；12种提取物对黄瓜炭疽病菌菌丝生长的抑制率大于50%；15种提取物对黄瓜炭疽病菌附着胞形成抑制率达50%。

ERAF17 gene expresses differently between male and female reproductive organs. Its expression is induced by ethylene or ethylene released compounds that can promote femaleness. No evidence directly shows the relationship between ERAF17 gene and femaleness, however. So this work focus on proving the positive correlation between the expression of ERAF17 gene induced by ethylene and development of female flowers,then search for the signal pathway of cucumber female reproductive organ development.

ERAF17基因在黄瓜的雌雄生殖器官的表达不同，可以由乙烯诱导表达，从而推动雌性化，但是它的作用机制却不清楚，并没有明确的证据表明ERAF17基因与雌花的发育有直接关系，所以本论文研究重点在于证明乙烯诱导ERAF17基因的表达对黄瓜雌花的分化有确定的正相关，从而可以探索黄瓜雌性器官发育存在的可能的信号通路，并对应用前景进行评估。

The cultivate techniques for Jinyou No.35 in Guantao county, Hebei province were summarized, the technique measures for high yield and high benefit cucumber cultivation in solar greenhouse, which consisted of variety selection, using of straw reactor, enhancing intertill management, delaying film covering on earth, temperature management and so on were definited for guide of the techniques, this demonstrate site produced cucumber yielding 477 000 kg/hm^2, gained benefit 907 125 yuan/hm^2, that is the new record of the county.

通过对河北省馆陶县寿山镇陈范庄村陈发恩、李保军、阎恩亮等6户菜农进行的津优35号黄瓜越冬长周期示范栽培进行总结分析，确立了温室黄瓜长周期高产高效栽培技术措施，包括良种选择，采用秸秆生物反应堆技术，营造良好的土壤团粒结构，适期早播，加强中耕管理，延迟扣地膜时期，植株调整、温度管理等。2008-2009年度，该示范点最高产量达到47.7万kg/hm^2，产值高达907125元/hm^2，创造了该县设施黄瓜越冬生产产量与产值的新记录。

With the increasing of NO3- concentration, the biomass, root absorbability and root absorbing area declined under NaNO3 treatment. The biomass was gradually increased with NO3- concentration increasing under Ca(NO3)2 and KNO3 treatments, while NO3- concentration excessed 98 mmol·L-1, the fresh weight of cucumber seedlings was gradually decreased.

NaNO3处理条件下，随着NO3-浓度增加，黄瓜幼苗生物量降低、根系吸收能力及吸收面积下降；而低浓度Ca(NO3)2及KNO3处理下，黄瓜幼苗生物量随着NO3-浓度增加而增加，当大于98 mmol·L-1时，黄瓜幼苗鲜重逐渐降低。

The result showed that correlation coefficients of disease indexes between downy mildew and powdery mildew were 0.619 8 and 0.677 2 at the seedling and mature stages respectively, which were extremely significant. The correlation coefficients of downy mildew and powdery mildew for BC1P1 and F2 individuals from the cross between K8 and K18 were 0.492 5 and 0.493 3, and they were 0.497 6 and 0.286 8 for the cross of K10 with K18, respectively. These four coefficients were all extremely significant too. By AFLP analysis, E25M63-103 marker was linked to some susceptible quantitative gene controlling both downy mildew and powdery mildew. The finding proved further some resistant gene of downy and powdery mildews linked to each other from molecular level.

结果表明：在苗期和成株期，29份黄瓜材料的霜霉病和白粉病病情指数之间的相关系数分别为0.619 8和0.677 2，均呈极显著正相关；K8×K18组合的BC1P1和F2群体的霜霉病和白粉病病情指数之间的相关系数分别为0.492 5和0.493 3，K10×K18组合分别为0.497 6和0.286 8，均达到极显著正相关水平；采用AFLP分析，发现E25M63-103标记与控制黄瓜霜霉病和白粉病的某个数量感病基因紧密连锁，进一步从分子水平验证了黄瓜霜霉病和白粉病某个杭性相关基因是紧密连锁的。

The 59 pure cultural isolates, including 3 Fusarium oxysporum f.sp.cucumarinum, 26 other Fusarium isolates and 20 fungi, 6 bacteria, 7 actinomycetes from cucumber rhizosphere, have been detected by PCR-RFLP and Nested-PCR. It shows that PCR-RFLP is special for the pathogen of Cucurbits Fusarium Wilt, and Nested-PCR is special for Fusarium oxysporum f.sp.cucumarinum.

本论文应用PCR-RFLP和巢式PCR程序对3株黄瓜尖镰孢菌(Fusarium oxysporum f.sp.cucumarinum)、26株镰孢属部分真菌及分离自土壤的20株真菌、6株细菌和7株放线菌共59个菌株进行扩增，表明PCR-RFLP程序对瓜类枯萎病菌具有特异性，而巢式PCR对黄瓜尖镰孢菌具有特异性，巢式PCR程序检测黄瓜尖镰孢菌的特异性高于PCR-RFLP程序。
