The materials in this study were arabidopsis thaliana. ( wt ) and its mutants including ethylene over producer mutant ( eto1 - 1 ), ethylene insensitive root mutant ( eir1 - 1 ) and ethylene insensitive mutant ( etr1 - 3 ). from the phenotypes of 12 - d - old seedlings of arabidopsis wt and mutants, the root gravitropism was obviously enhanced in etol - 1, but diminished in eir1 - 1 and etr1 - 3, compared with wt. the shoot negative gravitropism was also diminished in etiolated seedlings of etr1 - 3
以擬南芥的eth過量產生型突變體（ etol - 1 ） ，根對eth不敏感型突變體（ eirl - 1 ，地上部對eth響應） ， eth不敏感型突變體（ etrl - 3 ，地上部和根均對eth不敏感）及其野生型（ wt ， columbia生態型）為實驗材料，利用根的向重力性反應為模式，分析了其中eth對auxin效應的調控及其原因。 -

The results showed : the relationships among cover of herbaceous layer, cover of liver moss layer, thickness of liver moss layer, thickness of root system twine layer and the distance between seedlings and adjacent tree were positive correlation ; the relation between litter and tile above five variables were negative correlation ; the variables of micro - habitat affecting seedling in the picea schrenkiana stand were generalized with moss, herbaceous, spatial distance, humus and litter ; litter and spatial distance between seedlings and adjacent tree were the most primary factors of micro habitat affecting regeneration of one year seedling
結果表明：天山雲杉林分中草本層蓋度、苔鮮層蓋度、苔鮮層厚度、根系盤結層厚度、幼苗距大樹的距離5個環境變量之間為正相關；枯落物與草本層蓋度、苔蘚層蓋度、苔蘚層厚度、根系盤結層厚度、幼苗距大樹的距離為負相關；天山雲杉林微生境綜合因子可概括為「苔蘚」 、 「草本」 、 「空間距離」 、 「腐殖質」和「枯落物」 ；影響一年生幼苗更新最主要的微環境綜合因子為「枯落物」和幼苗距大樹的「空間距離」 。 -
The results showed that boron content had negative correlation with root weight, but had positive correlation with sugar content in cultivar tianyan309 ; on the contrary, boron content had positive correlation with root weight but had negative correlation with sugar content for cultivar baoyu30l, baoyu302 and zd204
結果表明，甜研309塊根中硼素含量與根重成正相關關系，與含糖率成負相關關系；而包育301 、包育302 、 zd204三個品種的硼素含量與根重成負相關關系，與含糖率成正相關關系。 -
