黃化(Etiolation)是植物在黑暗或持續弱光條件下生長發育異常的生理現象。典型特徵表現為莖稈纖細徒長、葉片黃化捲曲、機械組織發育滯後。該現象的核心機制在於光信號缺失導致葉綠體發育受阻,葉綠素合成相關基因表達受抑制。植物黃化狀態下,光合機構功能顯著受損,表現為淨光合速率下降、光能轉換效率降低。研究發現黃化苗中線...
黃化(etiolation)多數植物在黑暗中生長時呈現黃色和其他變態特徵的現象。植物在暗中不能合成葉綠素,顯現出類胡蘿蔔素的黃色;節間伸長很快;葉片不能充分展開和生長;根系、維管束和機械組織不發達。雙子葉植物的黃化幼苗胚軸頂端彎曲成鉤狀,頂芽展開很慢,子葉不膨大。黃化 【植物學】黃化(etiolation)多數植物在...
鄰近概念:chlorophyll deficiency(葉綠素缺乏症)、etiolation(黃化現象)診斷與防治 植物診斷流程包含:葉脈顏色比對:缺鐵型褪綠呈網狀黃化 土壤檢測:pH值高於7.5會顯著降低鐵元素有效性 葉面噴施:0.5%硫酸亞鐵溶液可快速緩解症狀 醫學防治著重於:膳食結構調整:增加血紅素鐵攝入量 藥物干預:右旋糖酐鐵注射劑用於...
19Inhibition of chlorophyll synthesis may be caused by etiolation, mutant blocks, or streptomycin.葉綠素合成可以由黃化、突變性阻塞或鏈黴素而引起。20Increasing the dose often leads to inhibition of other targets for which these drugs do not as fit well.增加劑量通常導致抑制其它這些藥物並不很適合的靶點...
光不但為植物提供光合作用所需的能量,而且還作為重要的環境信號,調控植物生長和發育的多個過程,比如種子萌發、幼苗去黃化(seedling de-etiolation)、避蔭反應、開花,等等。植物通過不同家族的光受體(photoreceptors)感受不同波長的光,其中光敏色素(phytochromes)特異感受紅光(600-700 nm)與遠紅光(700-750 nm)。擬南...
