The seed vigor, SOD and POD decreased significantly;and electric conductivity, the content of soluble sugar and MDA increased significantly.

而超干处理的种子贮藏18个月后，种子的发芽率、发芽指数、活力指数、电导率、可溶性糖含量、SOD活性、POD活性和MDA含量均无显著变化。

The results showed that with the immersion time of straw and straw leaching solution concentration increased, the germination rate of wheat seed decreases, the time of emergence of wheat seed also will extend the POD activity of wheat seedlings, SOD activity and root activity show a downward trend , leaf MDA content was increased.

结果表明，随着秸秆浸泡时间的延长和秸秆浸出液浓度的增加，小麦种子的萌发率随之降低，小麦种子的出苗时间也随之延长，小麦幼苗POD活性增加，SOD活性和根系活力呈现下降趋势，叶片MDA含量却升高。

The activities of CAT and POD during drying process were studied.It was found that the seed physiological activities increased at first and decreased at last.Effects of high temperature drying process on seed vitality were investigated in laboratory.The results indicated that there was some enzymes such as CAT and POD in the seed,which protected seed from destroy.

采用恒温恒湿干燥箱和生理生化实验台进行干燥和分离，测试了白菜种子内部的过氧化氢酶、过氧化物酶活性的变化，分析了高温干燥对种子生命特性的影响，结果表明，这些生命活性指标呈现钟罩型的变化趋势。

And he invented a combined plow and seeder.The seed went into a barrel with holes in it.

The root hair morphology of cv. RM109 was observed and compared. The results indicated that in the distance of 1 cm to the apical of seed root, the number of root hair of RM109 was 19% of cv. Oochikara, and the root diameters were not different from cv. Oochikara; in the distance of 8 cm, the number of root hair and the root diameters of RM109 were 45% and 79% of cv. Oochikara, in the distance of 3 cm, the length of the longest root hair was 33% of cv. Oochikara; but the length from the apical of the seed root to root hair initiation was not different.

根毛观察比较显示，距种子根根端1 cm处的RM109根毛数是&大力&品种的19%，差异极显著，根直径与&大力&品种差异不显著；距根端8 cm处的RM109根毛数和根直径分别是&大力&品种的45%和79%，二者差异极显著；距根端3 cm处，RM109最大根毛长是&大力&品种的33%，差异极显著；RM109种子根根端到根毛发生区的长度，与&大力&品种的差异不显著。

The short flowering shoots bend down as the seed ripens, and the seed may become buried in the sand.

当种子使成熟时，短花嫩枝弯腰，并且种子5月被埋在沙里。

The treatment of high-hydroscopicity resin seed-coatingmaterial can fornl a water-stored ball of about 1. 8 cm × 1. 5 cm × 1. 2 cm around seed and root, the ball has the abilities of absorbing, keeping and providing water. As the ball containing pesticide, germicide and plant regulatorand releasing slowly, it may afford a suitable surroundings for germination an...

高吸水种衣剂包衣处理在种子周围及秧苗根部形成了18cm×1.5cm×1.2cm左右的&蓄水球囊&，不仅提高了种子出苗率、成秧率，有效地防止了多种病虫害及死苗的发生，壮大根群，提高了秧苗素质；而且实现了旱育秧苗根部带土抛植，提高了立亩速度和抗植伤能力，增加了旱育抛栽稻的产量。

After the methanol phase extracted from pulp is treated by pocket resin, 50% alcohol eluent inhibitory is strongest. It can be included that the existence of seed inhibitor is the primary cause of the seed dormancy.

采用变温层积的处理方法来解除刺五加种子休眠，在实验室条件下，对刺五加种子进行层积处理，前期高温平均温度19.36℃(2～4个月)，后期低温时的平均温度为4.11℃(5～6月)。

The effect of lanthanum on the germination, MDA content and peroxidase activity in sorghum seeds under acid-rain stress were investigated. The objective of the study was to develop a scientific method and technical guide for mitigating acid-rain damage on seed germination.
