The results show that the germination rate of Hypericum perforatum seeds can reach over 65% after 3 weeks under experimental conditions.

结果发现，在试验处理条件下，三星期后皆可达到近60%以上的发芽率。

The results indicated that the three extracts from the M.maudiae leaves had inhibited the seed germination rate, the root length, seedling height and fresh weight of three plants to some extent, and the protein content and the activity of perxidase and hyperoxide mutase in the seedlings were also decreased. However, the content of malondiadehyde was increased.

结果表明，深山含笑叶片自然挥发物、水浸提液和挥发油降低3种受体的发芽率，对受体的根长、苗高和鲜重有不同程度的抑制作用；并均使3种受体幼苗蛋白质含量、SOD、POD活性降低，MDA含量增加。

The results showed that germination percentage and rate of germination decreased with increases in salinity, as well as the length of radicle and hypocotyl.

结果表明随着盐浓度的升高三种苜蓿的发芽率、发芽指数都受到不同程度的抑制，盐浓度越高，抑制作用越明显。

The results were as follows:The embryo-bud length, embryo-shoot length, embryo-shoot number and dry weight of embryo-shoot of maize inbreed line decreased evidently under osmotic stress within germinating period. So the germination date was delayed, the germination rate and viability decreased.

研究结果如下：在萌发期渗透水分胁迫条件下，玉米的胚芽长、胚根长、胚根条数、胚根干重等均有明显的下降，因而发芽时间延迟，发芽率下降。

The results were as the follows: maize inbreeds were sensitive to salt stress;different salinity stress had inhibition effects on the germination rate,shoot length,relative water content and net photosynthetic rate;different inbreed had obvious difference in salinity tolerance;the best one was XS98-28;the next was XSK5;the middle were in turn XSF,XS01-61;the lower were other inbreeds.

结果表明：玉米对盐胁迫非常敏感，不同盐浓度均对玉米芽苗期的发芽率、胚根长度、叶片相对含水量及净光合速率产生抑制作用；不同材料间耐盐性存在明显差异，各指标均能反映出不同材料的耐盐性；通过鉴定筛选，14个材料中，耐盐性极强的为XS98-28，耐盐性较强的为XSK5，耐盐性中等的为XSF，XS01-61，其余材料耐盐性均较弱。

But Lespedeza davurica increased only from 8% to 50%.The effect in hot water condition is indistinctive.

热水处理方法破除种子硬实的效果不佳，赤霉素处理对种子的发芽率几乎无影响。

Chlamydospores of kaoliang head smut treated under moist conditions at 32-35℃ inan incubator for 30 days,and then transferred to the cane-sugar solution,resulted 60 to 90%germination in contrast to only about 10% with the untreated control.

在32—35℃高温和湿润环境里处理30天后，就能完成厚垣孢子生理后熟的发育阶段，使孢子发芽率从10%左右提高到60—90%。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
