您要查找的是不是：
- The NRA was not directly correlated with nitrogenase activity. 硝酸还原酶活性和根瘤固氮活性之间没有直接关系。
- Soil drought reduced moisture content and nitrogenase activity of nodules. 土壤干旱降低田菁根瘤的含水量和固氮活性。
- The antigen activity is stronger of the fast-growing strains that of the slow-growing strains, and the nitrogenase activity of symbotic nitrogen ... 快生型菌株抗原性比慢生型菌株强,共生效应的固氮酶活性比慢生型菌株差。
- These results indicate that the decrease of nitrogenase activity of nodules under the boron-deficiency stress was not due to carbohydratedeficiency. 这说明了在缺硼条件下，根瘤固氮酶活性的下降并不是由于碳水化合物供应不足所造成的。
- The negative correlation between the total nitrogen content of leaves and fresh nodule weight,nodule nitrogenase activity were significant respectively. 叶片全氮含量与根瘤鲜重、根瘤固氮酶活性之间呈显著负相关。
- The effect of single factor on nitrogenase activity was larger than that of factors, the interaction of strains and varieties was larger than that of others. 单因素效应对固氮酶活性的影响高于因素间的作用，菌株与品种两因素间的交互作用大于其它交互作用。

- Leaf area was significantly correlated with plantlet height, leaf dry weight and stern dry weight.The correlation of nitrogenase activity (acetylene reduction) and leaf area was significant too. 叶面积与叶部含氮量间，叶面积与苗木之高生长、叶乾重、茎乾重以及根瘤活性与叶面积间皆呈极显著相关。
- There was a negative correlation between the nitrogenase activities of nitrogen fixing bacteria in root and that in leaf and stem. 上述结果说明：巴西甘蔗在本地也具有一定的固氮能力；
- Experiments carried out with wheat are reported in this paper. It showed that wheat root nodules could be induced by a certain concentration of 2,4-D, however, no nitrogenase activities of these nodules were examined by acetylene reduction method. 本文以小麦为试验材料,观察到一定浓度的2,4-D虽能诱发小麦根部结瘤,但结瘤后的小麦植株生长受到明显抑制,用乙炔还原法测不出这些麦瘤具有固氮活性。
- The relationship amongthe indices was analyzed.[Result]The nitrogenase activities inthe sugarcane varieties introduced fromBrazil were higher as compared to the native ones in general. [结果]不同甘蔗品种的固氮活性不同,其总体表现为巴西引进的甘蔗品种的固氮酶活性都高于当地主栽品种;
- The results indicated that treatment R1V2S2 and R1V1S1 had the highest nitrogenase activities, which were significantly higher than those of the two corresponding CK, respectively. 结果表明，处理R1V2S2和R1V1S1的固氮酶活性最高，二者都极显著高于两种阴性处理CK。
