| 1. | The ecological relationship of species , community and environment in elaeagnus mollis communities were studied by using twinspan and dca 本文应用twinspan分类和dca排序相结合的方法,研究了翅果油树群落的物种、植物群落与环境的生态关系。 |
| 2. | Elaeagnus mollis is one of the larger shrubs and dwarf trees , being an endemic to china and one of the china protected two - grade rare and endangered plants 翅果油树( elaeagnusmollis )是一种乔木状灌丛或小乔木,为国家2级珍稀濒危保护植物。 |
| 3. | This experiment also studied the transplanting technology of elaeagnus mollis diels tube plantlet and environmental conditions and the transplanting survival ratio was up to 66 % 本实验对翅果油树试管苗的移栽技术及环境条件进行了探讨,移栽成活率达66 。 |
| 4. | The community composed of elaeagnus mollis as the constructive species is one of the typical vegetation types in the hills and lower - mountains of southern of shanxi 以翅果油树为建群种形成的群落,是山西南部暖温带落叶阔叶林地带低山丘陵区的代表植被类型之一。 |
| 5. | The structural diversity of elaeagnus mollis communities was studied by using both extended shannon - weaver index and stvi ( structure index based on variance ) . the result from the both indices showed similar change tends 采用扩展了的shannon - weaver指数和stvi指数对翅果油树群落进行结构多样性研究,两个指数表现出较一致的变化趋势。 |
| 6. | Elaeagnus mollis is an endemic to china , being one of the state - protected two - grade rare and endangered plants , and distributed mainly in hills and lower - mountains in southern shanxi and at the northern foot of qinling ranges in shaanxi 翅果油树是我国特有种,为国家2级珍稀濒危保护植物,主要分布于山西南部的低山和丘陵区以及陕西秦岭北麓的户县。 |
| 7. | The nearest neighbors of each individual and the distances between each individual - neighbor pair in elaeagnus mollis communities were obtained by using the nearest neighbor ' s analysis . based on the primary results above , the spatial pattern and interspecific segregation in the communities were studied by x2 test with a subtable method of a n n nearest - neighbor contingency table 应用最近邻体法判定每个个体的最近邻体植株,得到每个基株-最近邻体种对的距离,进而采用n n最近邻体列联表的截表法,研究了翅果油数群落的种间分离。 |
| 8. | Elaeagnus mollis is one of the larger shrubs and dwarf trees , being an endemic to china and one of the state - protected two - grade rare and threatened plants , in china , elaeagnus mollis is only distributed in both shanxi and shaanxi , especially distributed mostly the south of luliang mountains and the midst and west of zhongtiao mountains , shanxi 翅果油树( elaeagnusmollis )是我国特有种,为大灌木或小乔木,是国家2级濒危保护植物。在我国,翅果油树仅在山西和陕西两省分布,尤以山西吕梁山南端和中条山中、西段分布较为集中。 |
| 9. | The different organs of elaeagnus mollis diels were used in this experiment as the explants . after establishing the aseptic propagation system , the aseptic tube stems and leaves were used to study the effect of different exogenous hormones combination and different culture conditions on organgenesis . the optimum medium and culture condition was screened for fast propagation of elaeagnus mollis diels 本实验选材为胡颓子科胡颓子属的翅果油树,在建立起无菌繁殖系的基础上,分别以试管无菌茎段和叶片为材料,研究了不同外源激素配比及不同培养条件对其器官分化的影响,从中筛选出适合翅果油树快速繁殖的最适培养基和培养条件。 |
