The effects of enhanced UV-B radiation on plant height and stem diameter of 10 wild sugarcane (Saccharum spontaneum L.) clones for 3 consecutive years under field condition was investigated.

wild Sugarcane； stem diameter ；研究了大田栽培和自然光条件下，连续3年模拟紫外辐射(UV-B，280~315nm)增加对10个割手密无性系伸长期株高和茎径的影响。

The results show that the secretory ducts are schizogenous cavity which are only distributed in the stem and the leaf.The initial of the secretory duct drives from the ground meristem.

结果表明，分泌道为裂生腔隙，只分布于茎和叶中；分泌道原始细胞起源于基本分生组织；分泌道原始细胞团裂隙的扩大靠鞘细胞的插入和上皮细胞自身的切向伸长；成熟的分泌道呈圆形或椭圆形，由一层上皮细胞和其外的1 ～2 层鞘细胞包被。

The results showed that intermidiate 1, 2-propanediol-sebacate of low relative molecular mass was synthesized with toluene-p-sulfoinc acid as catalyst, benzene as watercarrying agent, and of mole ratio of sebacic acid to 1, 2-propanediol of 1:4. The glass-transition temperatures of PPSC were below 0 ℃ which confirmed that PPSC would be in a high-elastic state of ambient temperature and human body temperature. PPSC was a elastomer with moderate crosslinkage, low module and high elongation, and had rapid degradation ratio (degradation degree more than 50%) in phosphate (pH value 7.4) at 37℃.

结果表明，以对甲苯磺酸为催化剂、苯为带水剂，在酸醇比为1，4的条件下可合成较低相对分子质量的中间体癸二酸聚酯二元醇；PPSC弹性体的玻璃化转变温度在0℃以下，于室温及人体温度下处于高弹态；PPSC为适度交联的、低模量高伸长的弹性体，其在37℃、pH值为7.4的磷酸盆缓冲溶液中具有较快的降解性（降解度超过50%）。

The inhibition substances in Sorbus pohuashanensisHedl fruit not only restrained the seeds of wheat, cabbage from germinating but also restrained height and root growth. After the seeds of wheat, chinese cabbage had been soaked in the water extraction of pulp, seed and decoated seed for 8h, the seed germination rates were 92% and 84%, 89% and 65%, 94% and 78%, lower than the control, especially the water extract of decoated seed; and the root length and seedlings height were lower than the control, especially the water extract of pulp, and decreased in sequence of soaking time from short to long. So the simplest and effective method to eliminate pulp soluble inhibiting substances is to wash fruits by flowing tap water soon after collection.

在几种浸泡时间中，浸泡8小时的去皮种子浸泡液对白菜、小麦种子发芽率的抑制作用最为明显，其发芽率分别为65%、89%，但随着浸泡时间的延长而降低；浸泡8h的果肉浸泡液对白菜和小麦幼苗高生长和根伸长的抑制作用最为明显，种子和去皮种子浸泡液(8h)的抑制作用对小麦和白菜的抑制作用次之，随着浸泡时间的延长，果肉浸泡液的抑制作用逐渐减弱，因而采收下来的果实及时净种是清除果肉水溶性抑制物质简单有效的方法。

The main characters of this category are: 1 It possesses clear main axes and lateral branches/sporangial stalks; 2 Sporangia terminate the lateral branches or long stalks; 3 With the distinct dehiscing mechanism, the sporangia have the variation in shape, i. e. reniform, rounded or vertically elongate; 4 Primary xylem is of centrarch maturation; 5 Conducting tracheid is G-type.

该类群包括Hsüa，Renalia，Nothia，Sartilmania和Huia，其主要特征为：1）具有明显的主茎轴及侧出的分枝系／孢子囊柄；2）孢子囊顶生于侧枝上或侧生的长柄上；3）孢子囊性状存在变异，为肾形、圆形或纵向伸长，具明显的开裂机制；4）初生木质部发生顺序为心始式；5）G-型输水管胞。

As the rachis of the inflorescence continues to elongate, sterile flowers with abortive male and female parts appear, followed by normal staminate ones with abortive ovaries.

由于脊柱的花序继续伸长，不育株花卉胎死腹中男性和女性似乎零件，然后按正常的雄花败与卵巢。

After analysis and measure the microscopic morphology and mechanical properties of mulberry and tussan silks which are being treated with stanniferous salts respectively, it is found that the erosion resistance of silk fibers after the weighting treatment has changed.

对经锡盐处理过的桑蚕丝和柞蚕丝进行了微观形态分析和力学性能测试，发现增重处理后真丝纤维的抗侵蚀性被改变，桑蚕丝的内应力减小，蠕变伸长变大。

Using Eriochome cyanine R staining, we found that Al accumulation on surface of root tips was positive related to the inhibition of root growth in treatments of 0 - 80μmol·L~(-1) Al for 24 h. Exchangeable Al in apoplast and symplasm of root tips of wheat was effectively desorbed by 5 mmol·L~(-1) CaCl_2 at 4℃.

铬化青R染色可以原位显示0-80μmol·L~(-1)Al处理后根尖表面Al的吸附量与根尖伸长受抑制程度具有很好的一致性。5mmol·L~(-1) CaCl_2溶液可以有效洗脱10和40μmol·L~(-1)Al处理24小时后小麦根尖质外体和共质体中可交换态Al。

This indicated that the actions of the hormone were not synchronistic to the pod lengths.

考虑到激素对代谢发生作用需要一定的过程和时间，这一情况正好反映了激素含量与角果伸长之间存在的不同步性。

I didn't watch TV last night, because it .
