休眠

Respiration was the most important limiting factor of fresh seed dormancy. Seeds without seed coat and aleurone layer germinated, but could not grow to normal seedling until finishing some metabolism. Drying could break fresh seed dormancy, but the effect of treatment with GA3 and H2O2 was not very significant.

呼吸是限制玉米鲜种子萌发的主要因素，去除种皮可以促使鲜种子萌发，但若要成长为正常幼苗还需体内代谢完成与幼苗生长有关的物质的合成，干燥可以使种子解除休眠，赤霉素、过氧化氢处理可一定程度解除鲜种子休眠，低温处理对解除玉米鲜种子休眠不起作用。

This experiment was carried out during 2002~2004 in Shan-dong Agricultural University. The dynamic changes of respiratory metabolism in dormant bud of two nectarine cultivars, Wuyuehuo and Shuguang, which have different Chilling requirements, were studied in the experiment. The soluble sugar, starch, soluble protein and amino acid in flower bud and scale, temperature, regulator, and shading were tested to discuss their effects on the respiratory metabolism.

本试验于2002年10月至2003年12月在山东农业大学进行，以需冷量不同的油桃品种曙光、五月火为试材，测定了不同需冷量品种的油桃花芽冬季休眠期间呼吸代谢的动态变化，以及呼吸基质及蛋白质和氨基酸的动态变化，探讨了呼吸代谢与自然休眠的关系；同时又测定了温度、遮荫、除芽鳞片以及生长调节剂对呼吸代谢的影响效果，探讨了影响油桃休眠的外界因子。

Dormancy break and germination of both seeds are accompanied by a decrease of ABA content in endocarp and seed coat, and by an increase of GA4 content in embryo.

山樱花和杨梅种子的休眠性质均属於生理休眠，种子的休眠解除和发芽皆需要伴随著种皮和内果皮的内在荷尔蒙ABA含量的降低和胚内GA4含量的增加。

Portable product is in dormancy condition inside most time, now and then move, the manufacturer can be through letting processor and other circuit inside most time the dormancy condition that is in feebleminded bad news, they let turn into specific power consumption when need higher high-powered position; The operation pattern of cereal song server differs completely: They complete right amount work inside most time, also need full load to move sometimes, but be in dormancy mode rarely.

便携式产品在大多数时间内处于休眠状态，只偶然运行一下，厂商可以通过让处理器和其它电路在大多数时间内处于低能耗的休眠状态，在需要时让它们转入能耗较高的高性能状态；谷歌服务器的运行模式则完全不同：它们在大多数时间内完成适量的工作，有时也需要全负荷运行，但很少处于休眠模式。

The results showed: the major causes were obstacle of seed vessel, seed embryo dormancy and post-maturation; the major methods were treatments of hypothermal stratification and growth regulators; naked layer stratification and sand layer stratification had cosistent effect on relieving seed dormancy; hypothermal stratification with GA3 500~1000mg/L for days could relieve seed dormancy, compared to sand stratification it shortened 30 days, and its germiation percentage was higher than that of sand stratification.

结果表明，引起砂梨种子休眠的主要有种皮障碍、种胚休眠和种胚后熟；而解除休眠的主要方法为低温层积处理和植物生长调节剂处理。裸层积和沙层积在解除种子休眠上的发芽效果是一致的，使用GA3溶液浸种，不能完全打破种子休眠，用GA3 500~1000mg/L低温层积30d即可解除种子休眠，比直接沙层积缩短30d，其发芽率比直接沙层积高。

After selective extraction, the cyst wall of two kind of resting cysts displayed a filament network. In the resting cysts of Tachysoma pellionella and Euplotes encysticus, the filament was located in mesocyst and endocyst respectively. On the other hand, a special filament scaffold region was observed below the cyst wall in two kind of cysts. Compared with the true IF which was located in central part of cyst, the filament of this region was net as well as uniform, and no any cytoplasm residue can be seen in this region. In the resting cyst of Euplotes encysticus, a filamental boundry which partitioned the special filament scaffold region and the true IF region was observed.

两类休眠包囊的包囊壁经生化分级抽提后均显示纤维结构，急纤虫休眠包囊中纤维定位于中间层，包囊游仆虫休眠包囊中纤维定位于内层壁；其次，在两类休眠包囊的包囊壁下，相当于细胞质表质层的位置，均有一个特殊的纤维网络区，与细胞质深层的网络区相比，此部分的纤维纯净、均匀，未见附着细胞器及细胞质残留物，在包囊游仆虫休眠包囊中此纤维网络区与真正的细胞质纤维网络之间由纤维构成的界膜隔开。

The use of chemical reagents on the grass to deal effectively break their dormancy, in order to clear the wild Pennisetum Eragrostis seeds and seed germination characteristics, determined to promote both the growth of grass seed germination and effective way to wild Pennisetum and Eragrostis large seed production and provide a basis to promote the use of this test, mainly through chemical reagents soaking, combined with a certain degree of mechanical processing, so as to achieve to break the dormancy of seed dormancy and promote germination and growth of its purpose.

利用化学试剂对草种进行处理能有效打破其休眠，为了明确野生狼尾草种子和大画眉草种子的发芽特性，确定促进这两种草种萌发和生长的有效方法，为野生狼尾草和大画眉草的种子生产和推广利用提供依据，本试验主要通过化学试剂浸种，并结合一定的机械处理，从而达到打破休眠种子休眠、促进其萌发和生长的目的。

The dormancy in FI population was secund to the heavy dormant parents in"heavy dormancy X heavy dormancy " combinations, while, it was secund to the weak dormant parents in "medium dormancy X heavy dormancy " combinations, in "weak dormancy X heavy dormancy " combinations, some were secund to the heavy dormant parents and some were secund to the weak dormant parents.

强休眠×强休眠组合中F_2休眠性偏向较强休眠亲本；中等休眠×强休眠组合中F_2休眠性偏向较弱休眠亲本；而弱休眠×强休眠F_2的休眠性有的偏向强休眠亲本，有的偏向弱休眠亲本。

The definition of dormancy process, the determination of dormancy depth and the effect of temperature on dormancy are the theoretical foundation of fruit trees bud dormancy study.

果树芽休眠进程的界定、休眠深度的确定以及温度对休眠的影响的研究是果树芽休眠研究的理论基础。

The main contents are as follows:(1) The seed dormancy types of halophytes;(2) The essential conditions for dormancy breaking of seeds in halophytes;(3) The correlation between seed germination of halophytes and salinity.

本文讨论了盐生植物种子的休眠、休眠解除及萌发的特点，主要内容有：(1)盐生植物种子的休眠类型；(2)打破盐生植物种子休眠的必要条件；(3)盐生种子萌发与土壤盐度的关系。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
