Root activity was expressed by - na oxidizing power 根系活力以-萘胺氧化力來表示。
Effect of soil deep tillage on root activity and vertical distribution 土壤深松對小麥根系活性的垂直分布及旗葉衰老的影響
Effect of deep tillage before winter coming on vertical distribution of root activity and senescence of flag leaf in wheat plant 冬前深耘斷根對小麥根系活性的垂直分布及旗葉衰老的影響
The result showed that the photosynthetic capability and root activity of the main rice in its later growth stage had significant effects on the development of ratooning buds 結(jié)果表明:主季生育后期的光合生產(chǎn)能力和根系活力對再生芽的發(fā)育有明顯影響。
Root activity was improved after re - watering , which suggests that rdi might restrain root growth and development qualitatively , but might improve root absorb performance by improving root activity 表明調(diào)虧在量上抑制根系生長,但在形態(tài)和吸收功能上表現(xiàn)出一定的補(bǔ)償效應(yīng)。
The plantlets grew much better in terms of root development ; the root activities , photosynthesis , regulating stoma and transpiration of them were significantly enhanced 主要表現(xiàn)在:植株健壯且根系發(fā)達(dá),有大量的側(cè)根形成;植株的根系活力、光合作用、調(diào)節(jié)氣孔開閉和控制蒸騰速率等方面顯著提高。
The results above suggested that water absorbing was limited by the inhibition of root activity . photosynthesis and the production of the photosynthesis was limited by the decrease of chlorophyll . . 52 . 54 % .青篙浸提液可通過抑制根系活力來影響水分的吸收,通過降低葉綠素的含量來影響光合作用及光合產(chǎn)物的生成與積累。
Relative water content of leaves , and root activity displayed a apparent reduction . the time of highest contains of soluble sugar appeared was moved up three days . the contains of soluble sugar were less than that of under 20 % peg ( 6000 ) treatment 4 、在本實(shí)驗(yàn)peg ( 6000 )處理中,生長與相關(guān)的水分生理指標(biāo)的變化主要受peg濃度的影響,而受脅迫處理時(shí)間長短的影響較小。
In the paper , if the amount of photosynthesis production accumlating in roots relected by root unit weight , the root unit weight and root activity varied with remained leaf of different leaf order , with marked negative correlation between root unit weiht and root activity 結(jié)果表明,當(dāng)單株按葉序僅留一片葉和不留葉時(shí),有限的光合產(chǎn)物能在根、莖與穗間協(xié)調(diào)分配,只是穗與根有輕微競爭,且兩品種均表現(xiàn)出了相同的趨勢。
The results showed that the cucumber seeds soaked with extracts of total alkaloid , dissoluble alkaloid and fat - soluble alkaloid from p . multisectum ( maxim . ) bobr . , the activities of amylase , protease and lipase during seed germination were inhibited , the seed vigor and germination rate were suppressed , and respiration rate of seedling was slackened ; root activity , chlorophyll content and activities of nitrate reductase , superoxide dismutase sod ) and peroxidase ( pod ) of cucumber seedlings during seedlings growth were increased 結(jié)果表明,多裂駱駝蓬總生物堿提取液、水溶性生物堿提取液和脂溶性生物堿提取液浸種均抑制黃瓜種子萌發(fā)過程中淀粉酶、蛋白酶和脂肪酶活性,種子活力和萌發(fā)速率降低,呼吸速率減慢;幼苗生長過程中根系活力、硝酸還原酶活性升高,葉綠素含量增加,超氧化物歧化酶( sod )和過氧化物酶( pod )活性提高。
