Although both of FDRMADS7 and FDRMADS8 wereexpressed in the root, they have different expression pattern.The transcripts of FDRMADS7 weredetected throughout the root,especially the expression in the root meristem was the highest.However,the expression of FDRMADS8 was mainly localized in elongation and mature rigion.No apparent expression signal was detected in the root cap, root meristem and pericycle cells.

虽然FDRMADS7和FDRMADS8都在根中表达，但它们在根中的表达模式也不相同：FDRMADS7在根中到处表达，尤以生长点处表达量最高；而FDRMADS8在伸长区和根毛区的皮层中有大量表达，在根冠，根尖分生区和根毛区的中柱鞘细胞中却无明显表达，暗示它们在根中行使的功能也不相同。

According to the root type division the Chinese Dwarf cherry belongs to the inductive type of root primitive body,From above several aspects we can see that the mechanism of soft-wood cutting is : Under the condition of without root primordium ,the root primordium appear from cambium by using rooting accelerator under the condition of well temperature ,humidity ,and light, then the root primordium breaks through the cerebral cortex, finally extends to outside .

从以上几个方面我们可以看出，欧李嫩枝扦插生根繁殖的机理为：欧李嫩枝在无根原体存在的情况下，经过生根剂的处理在合理的温度、湿度及光照条件下，由其形成层部位产生根原体，随后根原体突破皮层，伸向外部。

Root hairs of wild type were intensely induced in the presence of NAA, while the gls mutant was insensitive to NAA induced root hair initiation; Lateral roots of the wild type were dramatically decreased when treated with 2,4-D, while the gls mutant was insensitive to 2,4-D induced reduction in lateral root initiation; The seminal root length of wild type showed no obvious changes by the treatment with IAA, but the gls mutant was supersensitive to IAA with dramatic reduction in seminal root length, suggesting that the interactions of GLS gene with different hormones may involve different mechanisms.

外源NAA 处理强烈诱导野生型根毛发生，而gls突变体则不敏感；外源2，4-D处理，野生型侧根急剧减少，gls突变体则不敏感；外源IAA处理，野生型种子根长变化不明显，而gls突变体超敏，种子根长迅速变短，表明GLS基因与不同激素有不同的互作机制。

In the process of root cutting, the root accumulated a lot of soluble sugar and soluble protein, which provided material and energy for the cell differentiation. As root differentiating, soluable protein was continuously used up. During 10 to 20 days, the content of soluble sugar and soluble protein in the basipetal top and end of rootkept comparatively stable, then declined as adventitious buds and roots growing. 40 days later, they kept invariable, because the newly formed bud can photosynthesize and the newly formed root can absorb nutrient from outside. The dynamic balances of endogenous hormone regulate adventitious buds and roots of the root. During callus growing and adventitious bud differentiating.

上部根段在细胞分化前期积累了大量的可溶性糖，为后期的分化提供能源物质，同时积累了大量的可溶性蛋白质，为愈伤组织的产生提供能源，而后随着分化，可溶性蛋白质不断被消耗。10～20d根段上部及下部的可溶性糖、可溶性蛋白质含量保持在相对稳定的水平变化不大，后期随着不定芽及不定根的生长下降较快。40d后，新形成的芽已经能够进行光合作用，新形成的根也可从外界吸收营养物质，可溶性糖、可溶性蛋白质含量基本保持不变。

Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

In order to assess the change of triploid populus tomentoza pulp plantation long-term-site productivity, The paper studied on effects of aboveground litterfall, fine root turnover and wet dust precipitation in nutrient cycling of triploid populus tomentoza pulp plantations at different ages,namely 2a、4a、5a、6a.It studied influence of different factors on decomposition of leaf、tree bark and twig of triploid populus tomentoza to select the operations to accelerate the decomposition and nutrient release. Finally, it studied influence of different intercrops on plantation site productivity and the relationship of intercrops and triploid populus tomentoza to select suitable intercrops. The main results as follows:(1)The aboveground litterfall of triploid populus tomentoza increased along with age from 216.03±59.7gm~(-2) at 3a to 482.38±101.3gm~(-2) at 7a, The N returned by litterfall wasl8.38±2.46kg.hm~(-2)a~-121.63±2.25kg.hm~(-2a~-139.51±4.61kg.hm~(-2a~-138.89±4.89kg.hm~(-2a~(-1) at 3a、5a、6a、7a respectively.

The leaf was the principal pathway to return nutrient to soil among litterfall, fine root turnover and wet dust precipitation. The proportion of returned N by leaf was 74.84%、71.96%、78.58%、75.03% at 3a、5a、6a、7a respectively,The proportion of returned P by leaf was 85.93%、80.31%、83.04%、83.23% at 3a、5a、6a、7a respectively. Therefore, it is important to protect and utilize the leaf in order to maintenance and enhance the long-term-site productivity of triploid populus tomentoza pulp plantation.
