查询词典 seed coat

The results showed that soil type had significant effects on the root morphology and nodule traits of test varieties. In alfisol, the root dry mass, root length, and root surface area of test varieties were greater at the fifth trifoliolate stage and bloom-beginning stages while smaller after seed-beginning stage, compared with those in mollisol, and the average root diameter after seed-beginning stage was higher in alfisol than that in mollisol. Soil type did not affect root-shoot ratio. The nodule number after seed-beginning stage was much smaller in alfisol than in mollisol, while the nodule fresh mass and the mass per nodule were in adverse.

结果表明：土壤类型对大豆根系形态及结瘤性状均有显著影响，在第5片复叶展开期和初花期，暗棕壤的根系干质量、根长和根表面积低于黑土，而在鼓粒初期后高于黑土，暗棕壤的平均根直径在鼓粒初期后也高于黑土，但土壤类型对根冠比的影响不大；暗棕壤的根瘤数在初花期后明显低于黑土，但根瘤鲜质量和单个根瘤质量高于黑土。

The results showed that O. fragrans seeds were desiccation-sensitive as the seed viability declined to 6% when the seed moisture content was reduced to 11.6%. The seed electrical conductivity increased with the declining moisture content, a sign, which was caused by increasing cell membrane cleavage. Superoxide dismutase activity decreased rapidly during desiccation; but peroxidase activity increased to the maximal value when dehydration for 12 h, then declined rapidly when seeds were dehydrated more than 12 h.

结果表明：'紫柄籽银桂'种子不耐脱水，种子生活力随着含水量的下降而降低，种子含水量下降到11.6%时，生活力仅为6%；自然脱水过程中，种子细胞膜系统受到损伤，相对电导率不断上升；种子内SOD活性随着含水量下降而呈总体下降的趋势；POD先呈波动性上升，脱水12 h时达到最大值，之后急剧下降。

The calcium sulfate was dissolved and led to the rapid increase of calcium ion concentration in the solution. So the calcium sulfate is not suitable for being seed crystal of low-salt concentration. The quartz sand and calcium carbonate both can be used as seed crystals, but it is much faster and more complete to use calcium carbonate as seed crystal compared with using quartz sand.

当硫酸钙加入处理液中发生了硫酸钙溶解现象，导致溶液钙离子浓度迅速增加，故硫酸钙不适合做低浓度盐水的晶种，而石英砂和碳酸钙均能对钙离子的结晶起到效果，但碳酸钙做晶种对钙离子的结晶更快捷、更彻底，在条件允许的情况下，采用碳酸钙做晶种为宜。

Because of the problems and its related reason which existed in the service of the clamping and self-locking cotton precision dibblers, the seed-blocking ring and the seed discharging mechanism were designed and the seed-filling equipment was improved.

针对夹持自锁式棉花精量穴播轮在使用中存在的问题及其产生的原因，设计了挡种圈和投种器，改进了取种机构。

The density of the foot 、middle part and top are 124grain /m~2、91 grain /m~2、66 grain /m~2,the seeds is more little windward than the leeward.The density of seed banks in windward is 81grain/m~2 and the leeward density is 100grain/m~2.The seed of ephemerals bourgeoning reaches the pinnacle on April and May.The diversity of different parts sand dune is different,but the differences do not reach the marked level.The similarity is high between the seed banks and the vegetation.

迎风坡种子库密度比背风坡面少，迎风坡种子库平均密度为81粒/m2，而背风坡种子库平均密度为100粒/m2；短命植物种子在4月上旬达到萌发高峰，沙丘不同部位物种多样性存在差异，土壤种子库和地上植被存在较高的相似性，此外短命植物在沙丘不同部位的分布存在较高的空间异质性。

The effects of temperature and time on the autooxidation of hemp seed oil and the effect of antioxidants on antioxidation ability of hemp seed oil were studied by Schaal experiment according to POV of hemp seed oil.

采用Schaal烘箱法，以过氧化值为指标，研究温度、时间对汉麻籽油自氧化过程的影响及添加抗氧化剂对汉麻籽油抗氧化性能的影响。

To evaluate the allelopathy effects of benzoic acid and ρ-hydroxybenzoic acid on watermelon, this paper studied the effects of benzoic acid and ρ-hydroxybenzoic acid on watermelon seed germination and seedling growth by seed soaking, seed-bud soaking and seedling irrigation.

为探明苯甲酸、对-羟基苯甲酸对西瓜的化感作用，采用浸种、浸芽和浇灌幼苗的方法分别研究了苯甲酸、对-羟基苯甲酸对西瓜种子发芽和幼苗生长的影响。

The results showed that the seed germination percent decreased both in benzoic acid and ρ-hydroxybenzoic acid seed soaking treatments and the growth of hypocotyls and radicles in the seed-bud soaking treatments were inhibited significantly.

结果表明，苯甲酸、对-羟基苯甲酸浸种处理使西瓜种子发芽率显著降低；浸芽处理使西瓜种芽的胚轴、胚根生长受到显著抑制。

Item that be export from India:- black pepper , dill seed , cellery seed , poppy,turmeric , cummin seed , ginger , etc .
