SEM observation shows that,the micropyle in mature seed is closed,hilum possesses hilar groove under which there is reticular tracheidal bar,which function as for water-storage and permeation.From out inwards the seedcoat includes four layers viz cuticle,palisade,osteos- clereid and parenchymatous layer The structure of hilum and/or seedcoat was damaged by treating the seed with various kinds of organic solvents and concentrated sulfuric acid in dif- ferent durations or by mechanical methods,was found that surface layer and hilum were erosion-nonresistant;the palisades had thick cell walls and were orderly arranged,and con- tain phenols.They are the main barrier controlling the entrance of water through seedcoat. Erosion with concentrated sulfuric acid and mechanical damage of seedcoat are effective me- thods for overcoming its impermeability and raising germination capacity of seeds.The factors effecting permeability of seeds and their control mechanism as well as the nature of“light line”of palisades were discussed.

扫描电镜观察表明:成熟田菁(Sesbania cannabina)种子的种孔闭锁,种脐具有种脐沟,沟下有一网状管胞群,具贮水和通气功能;种皮的结构由外向内依次为表层、栅栏层、骨状石细胞层及薄壁细胞层。作者用多种有机溶剂浸泡、不同时间浓硫酸腐蚀和机械损伤等方法有控制地损伤种脐和/或种皮的不同层次结构,发现表层和种脐不耐腐蚀,栅栏层细胞壁厚,排列紧密有序,并具有酚类物质,是控制水分进入种皮的主要屏障。适度浓硫酸腐蚀和机械损伤是克服种子不透性,提高萌发率的有效途径。文章还讨论了影响种子透性的因素,作用机理及栅栏层中“亮线”的实质。

A general diffraction formula for plane apertures is derived by quantum theory and the results are in keeping with the present diffraction theories that attained by other methods. The viewpoint of photon diffraction can help us understand the nature of light diffraction and the evanescent waves is necessary for the uncertainty principle.[WT5”HZ]

There were two representative opinions about the nature of light in ancient China. Some believed light was a kind of gas released from light source. Others represented by the 17th century scientist Fang Yizhi regarded light as the spread of the interaction of air. From that view, a primitive theory of light wave was developed. About the transmitting range of light, the ancient people thought light could only transmit in limited distance. They often used the theory to discuss astronomical problems. Since they hadono idea of “action at a distance” in ancient China, Chinese people thought it took light time to transmit and it traveled at a high speech. In which way does the light speach? The ancient Chinese believed that when travelling short distance, light traveled rectilinearly; and when travelling long distance with certain conditions, light traveled in curve. That theory reached its top when Fang Yizhi raised the concept that “light is fat and shadow is thin”, which is corresponding to his theory of light wave.

在对光本性的认识上 ,古人有两种典型说法 ,一种认为光是由光源发出的某种特殊的气 ;另一种则以 17世纪科学家方以智为代表 ,认为光是气内部相互作用的传播 ,并由此发展出了一种原始的光波动学说。在对光的传播范围的认识上 ,古人认为光行有限 ,并广泛应用这种观念来讨论天文学问题。在对光速的认识上 ,古人没有超距作用观念 ,他们先验地认为光的传播需要时间 ,光速极大。在对光的传播方式的认识上 ,古人认为 ,光的传播近程时沿直线而进 ,远程时 ,在一定条件下 ,依曲线而行。这一认识发展的顶峰是方以智的“光肥影瘦”说 ,该说与他的波动光学思想是一致的
