| 1. | The drought tolerance of sorghum is stronger than that of maize , its leaf relative water content and water potential are higher under drought condition 高粱耐旱性较强,干旱条件下叶片相对含水量较高,水势亦较大。 |
| 2. | The water content of media had great influence on germination and the seeds could get the best germination when the relative water content was 70 % 基质含水量的差异对种子发芽影响较大,相对含水量为70 %时,种子发芽效果最佳。 |
| 3. | Shading decreases transpiration rate and content of bound - water , but raises relative water content . so it weakens the resisting contrary ability 遮荫降低了蒸腾速率,提高了相对含水量,降低了束缚水含量,抗逆性能力减弱。 |
| 4. | The results showed , under the stress of continuous drought , the relative water content of leaves had a descending trend , while the penetration of membranes lightly increased 研究结果表明:供试材料在连续干旱胁迫下,叶片相对含水量呈下降趋势,质膜透性有所增加。 |
| 5. | The results with grey correlative degree analysis showed that chlorophyll content , water potential of leaves , relative water content and electric conductivity can be regarded as the important indexes of drought resistance evaluation of the species 关联度分析结果表明:叶绿素含量、叶水势、叶片相对含水量以及电导率可作为3树种重要的抗旱评价指标。 |
| 6. | 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 、在本实验peg ( 6000 )处理中,生长与相关的水分生理指标的变化主要受peg浓度的影响,而受胁迫处理时间长短的影响较小。 |
| 7. | T . media cv . hicksii seedling hi natural light has higher content of bound - water and water saturation deficit , bigger transpiration rate , and lower relative water content , stronger ability of fighting loss water than that in shading light intensity conditions 自然光照条件下生长的曼地亚红豆杉幼苗蒸腾速率较大,叶片相对含水量较低,水分饱和亏缺值较大,束缚水含量较高,抗脱水能力最强。 |
| 8. | Relative water content ( rwc ) , operation and development of alternative pathway , the changes in active oxygen species ( aos ) and activities of antioxidant enzymes , and the role of alternative pathway participating in the protection mechanism against environment stress were studied and discussed in wheat seedlings leaves under combined intimidation of water stress and pathogen infection 摘要以抗旱性和抗病性不同的小麦为材料,以正常生长为对照,观察了病原菌和水分复合胁迫对小麦叶片相对含水量、活性氧代谢以及对抗氰呼吸的发生、运行的影响。 |
| 9. | ( 5 ) the synthetic draft curve was conducted by crop coefficient and relative soil moisture . the correlation in crop coefficient and relative water content takes on uniform trend comparing to the soil water deficient degree . in the whole growth season of cotton , the high correlation coefficient occurred in the period of seeding , which was declined in the period of blooming and flowering , whereas it was raised in the late period of cotton ( 5 )综合作物系数与相对含水率拟合关系表明,作物系数与含水率的相关性与土壤受旱的情况呈现相同的趋势,苗期的相关系数高,而到了蕾期偏低,花铃期更低,到了吐絮期有所升高,整体上表现为水分状况良好,相关性就越高。 |
| 10. | Through cultivating five cold - season turfgrass ( lolium perenne , agrostis stolonifera , festuca rubra , festuca arundinacea , bromus inermis ) in basin , their drought to lerance indexes , including the planting height , the root growth , the relative water content of leaves , the penetration of membrane , were comprehensively evaluated to compare their drought tolerance 摘要采用盆栽育苗法,在5种冷季型草坪草苗期连续干旱胁迫下测定植株高度,根系生长,叶片相对含水量和质膜透性等抗旱指标,以综合评价5种冷季型草坪草的抗旱性能。 |
