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于枳；但枳的黃化葉片的總鐵含量高于香橙和枳的綠色葉片。

The chlorosis develops from light yellow to tan , becoming brown and finally drying to a “ scorch “ 褪綠部分由淡黃色演變為黃褐色以至褐色，最終變干呈“灼傷狀” 。

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,邊緣向下卷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

Fruit trees are very important economic crops in people ' s life , the losses of fruit production caused by iron chlorosis are usually higher than those of other annual economic crops because fruit tress , as perennial plants , will remain there for many years after they are planted in a field and an evident accumulation effect may take place 果樹作為一種與人民生活密切相關的重要經濟作物，由于其本身的特點，缺鐵造成的產量損失遠比一年生作物嚴重，因為果樹一旦栽培在土壤中便很多年不移動，所以有明顯的缺鐵積累效應。

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于香橙。

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。

General yellow - green or yellow interveinal chlorosis of fully expanded and younger leaves with major veins and most minor vein clearly defined green without appreciable adjacent green lamina ; some younger leaves with profuse interveinal brown necrotic spotting 甜菜缺鐵：完全展開葉的脈間褪綠一般黃綠色或黃色，嫩葉的主脈和大部分側脈明顯顯示綠色沒有可察覺的相連的薄層；一些嫩葉脈間有大量褐斑。

C . junos and m . xiaojinensis were found to be tolerant to iron chlorosis and were able to acquire iron from soils of low iron availability in previous field experiments , but the physiological and molecular mechanisms for their iron efficiency have remained unclear 基于此，本研究選擇了兩種果樹砧木，小金海棠和香橙因為它們在初步的田間鑒定中表現耐缺鐵，但它們耐缺鐵的生理及分子機制并不清楚。

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。

Unfortunately , the widespread problem of iron chlorosis of fruit trees remains poorly understood and the results of the methods for its correction are not satisfactory , and they sometimes cause serious environmental problems as well 可是，時至今日缺鐵現象還沒有完全被人們認識清楚，現行的矯治措施也收效不大，有些甚至還帶來嚴重的環境問題。

Older leaves first affected with bright yellow - green or yellow interveinal chlorosis , inrolling of margins , wilting , bleaching and withering before dehiscing prematurely ; youngest leaves and growing point persist for longest period 老葉首先脈間失綠呈嫩黃色或黃色，邊緣不卷曲，在過早地裂開前白化并干枯，心葉和生長點能持續最長地周期。

Almost white interveinal chlorotic banding in oblique patches . an “ indicator ” condition for nickel excess which is quite distinct from yellow - green or yellow interveinal chlorosis caused by simple iron deficiency 鎳中毒的燕麥葉片：脈間幾乎都是帶有斜斑的白帶；鎳過剩的顯示癥狀不同于由單獨缺鐵引起的脈間褪綠黃綠化或黃化。

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，葉緣不卷曲，葉尖端枯萎，葉片脫落。

Irregular marginal and interveinal yellow green chlorotic areas , followed by general interveinal chlorosis and profuse brown necrotic spotting and scorching , typical also of field conditions 菜豆錳中毒：不規則邊緣和脈間區開始黃綠色，接著全部脈間失綠，并有大量褐色壞死斑點，最后枯萎。也是典型的田間情況。
