leaf chlorosis 中文意思是什麼
leaf chlorosis
解釋
葉褪綠病-
Yellow - green or yellow chlorosis or brown necrosis in basal areas of older and expanding leaves ; margins curled downwards and leaf expansion irregular and suppressed ; chlorosis and necrosis spreading into interveinal areas of older leaves ; youngest leaves distorted, necrotic and failing to expand ; petioles truncated ; death of stem growing point
西葫蘆缺硼:老葉和正展開葉的基部黃綠色或黃化或變褐壞死，邊緣向下捲曲和葉片展開不規則和抑制，色斑和壞死斑散布在老葉葉脈間，心葉扭歪、壞死、無法展開，莖生長點枯死 -
Older leaves ( except sometimes the first leaf and also cotyledons ) show bright yellow or orange blotchy interveinal chlorosis, leaf margins are inrolled. tips of leaflets scorch and leaves wither
番茄缺鉬葉片：老葉（除此之外第一片葉和子葉有時也會）出現嫩黃色或橙色斑點的葉脈脈間失綠，葉緣不捲曲，葉尖端枯萎，葉片脫落。 -
Foliage is dark green, leaflets of older leaves have convex curvature ; profuse, almost black necrotic speckling between veins ( often appearing first on under surfaces ) coalesces into larger marginal and intervernal areas with occasional slight marginal chlorosis, followed by total scorch and leaf collapse
缺鉀的馬鈴薯葉片:葉片暗綠，老葉的葉片表面彎曲，大量的黑色壞死斑紋出現在邊緣與葉脈連接處和稍微葉邊褪綠的葉脈間，逐漸枯萎壞死。 -
The physiological reaction of c. junos under iron stress in field experiments, c. junos manifested itself as tolerant to iron stress. no chlorosis symptom was not found in its leaves when it was grown in a soil with ph 7. 8. in contrast, severe chlorosis was found in the control plant p. trifoliata grown under the same soil conditions, and leaf chlorophyll content as an indicator for the degree of fe deficiency in p. trifoliata was much lower than in c. junos
主要的研究結果如下： 1 ：鐵脅迫下香橙的生理反應研究香橙在田間實驗中表現耐缺鐵，在ph7 . 8的土壤中生長正常，葉片無任何缺鐵癥狀；但對照植物枳在同樣土壤條件下卻表現出明顯的缺鐵癥狀，作為缺鐵程度指標的葉片葉綠素含量極顯著低於香橙。 -
Iron deficiency causes interveinal chlorosis, mesophyll yellowing or paling and leaf size reduction and, if severe enough, retards the growth of the plants and may even cause their death, thus resulting in great losses to agricultural production
植物缺鐵，葉片脈間失綠，葉肉發黃甚至變白，葉片縮小，如果缺鐵癥狀嚴重，會引起生長停滯甚至死亡，給農業生產造成嚴重損失。 -
In solution culture, evident chlorosis symptoms were observed in the leaves of p. trifoliata after 4 weeks of iron deficiency treatment, while no chlorosis symptoms were observed in the leaves of " iron efficient " c. junos under the same culture conditions. the content of leaf chlorophyll and active iron in c. junos was much higher than that of p. trifoliata. however, iron content of chlorotic leaves of p. trifoliata was found to be even higher than that of the green leaves of p. trifoliata and c. junos
枳在缺鐵營養液中培養4周即可出現明顯缺鐵癥狀，而生長在同樣時間內和同樣缺鐵培養液中的香橙觀察不到任何缺鐵癥狀，香橙的葉片葉綠素和活性鐵含量均極顯著高於枳；但枳的黃化葉片的總鐵含量高於香橙和枳的綠色葉片。
