Pvx在许多品种上表现脉间花叶。 |
| 3. | Leaves show bright yellow interveinal chlorosis , usually more acutely in apical areas and in younger leaves followed sometimes by bleaching and scorching
叶片脉间黄化，通常在叶尖和嫩叶上更为严重，有时转变成白化并枯黄。 |
| 4. | Blotchy irregular interveinal fading and orange - yellow chlorosis of older leaves , margins culed and sometimes scorched ; younger leaves remaining green
甜菜锰中毒：带有不规则斑点的叶脉间褪色，老叶变为桔黄色，边缘卷曲，有时枯萎，幼叶保持绿色。 |
| 5. | Blotchy interveinal yellow - green mottling and marginal yellowing of expanded leaflets ; irregular brown necrotic patches ; wavy margins and down - curved leaf tips
矮生菜豆缺锌：带泡的脉间形成黄绿色斑纹,展开的小叶边缘黄化及不规则的褐色坏死斑点,波浪形边缘,叶尖向下卷曲 |
| 6. | Younger leaves faded green and lusterless ; older leaves marginal scorch , interveinal blotchy chlorosis , necrotic patches bleaching and withering ; characteristic of some soil acidity conditions
甜菜锰和铝合并中毒：幼叶褪绿失去光泽，老叶边缘枯黄，脉间有坏死褐色斑点，接着白化，枯萎。这是酸性土壤特有的。 |
| 7. | 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
菜豆锰中毒：不规则边缘和脉间区开始黄绿色，接着全部脉间失绿，并有大量褐色坏死斑点，最后枯萎。也是典型的田间情况。 |
| 8. | 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
番茄缺钼叶片：老叶（除此之外第一片叶和子叶有时也会）出现嫩黄色或橙色斑点的叶脉脉间失绿，叶缘不卷曲，叶尖端枯萎，叶片脱落。 |
| 9. | 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
镍中毒的燕麦叶片：脉间几乎都是带有斜斑的白带；镍过剩的显示症状不同于由单独缺铁引起的脉间褪绿黄绿化或黄化。 |
| 10. | 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
老叶首先脉间失绿呈嫩黄色或黄色，边缘不卷曲，在过早地裂开前白化并干枯，心叶和生长点能持续最长地周期。 |
