Results There was no obvious discrimination of the seed morphology between AMM and AM.

结果通过肉眼和光学显微镜观察，两种黄芪种子的形态差异不明显，在电子显微镜下观察，两种黄芪种子的萌发孔形状、种脐和种皮的微观结构有明显差异；蒙古黄芪较膜荚黄芪种子硬实率高，萌发不整齐，萌发高峰滞后。

In the thesis, we choose six wild species in northeast of China to study the configuration, physiological characteristic, peculiarity of dormancy and bourgeon as well as seedlings growth process. The results as follows:(1) Morphological difference of six species in Iris is obvious.

基于此目的，本论文以东北野生鸢尾属中的6种典型植物为研究对象，从种子形态结构、种子各项生理指标(包括生活力、含水量、吸水性)、种子的休眠与萌发、种苗的发育过程几个方面进行研究。

Compared with the control, the exudate treatment significantly hampered the percent germination, rate of germination and bolstered dormancy for almost all species.

与对照实验相比，种子浸出液处理对种子的发芽率、发芽速度均具有明显的抑制作用，并能增强种子的休眠。

Statistical methods designed specifically for mapping QTL controlling endosperm trait have been proposed by several researchers in recent years, but these methods all ignored the influence of the maternal genom.

谷类作物种子的整个发育过程是在母体植株上完成的，母株为种子提供库容和营养，因此种子胚乳性状和胚性状的遗传表达除了受胚乳和胚自身基因型控制以外，还可能受到母株基因型影响。

The results of experiments showed that Lanthanum nitrate accelerated germination and increased seed vigor of rice.

用5~25mg/L浓度的La(NO3)3溶液处理萌发期间的水稻种子，表明能加快种子的萌发，提高种子活力。

It was observed that low salt con-centration had a stimulating effect on germination.In general,the percentage of germination declined withsalt concentration increasing.The response of stylo seeds to salt stress varied with a changing concentra-tion and the type of salt used in individual treatment.

结果表明，低盐浓度对部分柱花草种子萌发有促进作用；随着盐处理浓度增高，发芽率一般呈下降趋势，但也有例外；不同浓度的盐胁迫下柱花草种子的适应情况不同，同一柱花草种子在萌发时对不同盐的适应情况也不同。

The dormancy reason that the article summed up officinal plant seed and promote the method that cultivates seminal bud, for the gemmiparous experiment of officinal plant seed, optimize grow seedlings, promote quality of high school medicinal material, increase crop to provide reference.

本文综述了药用植物种子的休眠原因和促进种植种子萌发的方法，为药用植物种子的发芽试验，优化育苗，提高中药材质量，增加产量提供参考。

But when we examined the structure of cultivar of D. huoshanense, endomycorhiza was founded unexpectedly. And in the wild type of D. huoshanense, fungi was also founded in its stems and leaves. So the author thought that endomycorhiza is not only located in the roots of Dendiobium plants, but also exists in other organs of plants, including stems, leaves. As plant produces seeds, mycorhiza could enter into the cells of seeds. When mature seeds germinate in media, the endomycorhiza enter into the roots of cultivar.

石斛属植物与真菌共生，根为菌根，作者在研究霍山石斛组织培养型结构时发现，组织培养苗的根部也分布有真菌，而且在野生霍山石斛的茎、叶中发现有真菌，作者因而指出，真菌并不是完全分布在根部，而是遍布于整个植物体，推测植物形成种子时，真菌进入种子，所以在组织培养时，真菌随着种子的萌发，进入植物体根部。

Models have been developed for predicting sound seeds and total seeds per cone by means of the cone cuttingfor Chinese fir. Number and quality of seeds per cone have been analysed and estimated.

本文利用球果切开法建立了预测杉木全果饱满种子数和种子总数的预测模型，同时对杉木球果中种子的产量和质量作了估测和分析。

This kind of crop seed dryer is made for Laiyang Agriculture college dry technical lab which is the emphases lab in Shandong province.

本谷物种子干燥机是为山东省重点实验室莱阳农学院旱作技术实验室设计制造的，要求每次干燥种子重量小于等于100公斤，保证不出现串种，保证种子的生物安全性，自动化程度高、干燥速度较快。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
