氯化和坏死之间的差异

Thekey differencebetween chlorosis and necrosis is thatchlorosis is yellowing of plant tissues as a result of decreased amounts of叶绿素, while necrosis is the death of plant cells or tissues.

由于疾病，伤害或营养缺乏，植物显示出不同的症状。一些常见的症状包括氯症，坏死，枯萎，马赛克和斑驳以及浸泡。氯化是叶子上黄斑的外观。它由于缺乏叶绿素而发生。相反，坏死是由于植物细胞或组织死亡而导致叶片上棕色斑点的出现。

什么是氯化？

Chlorosis refers to the yellowing of plant parts, mainly leaves and veins. Yellow spots appear on the leaves, giving a mosaic pattern. Yellowing occurs due to insufficient amounts of chlorophylls. Chlorophyll production can be decreased due to many reasons. One of the major reasons is nutrient deficiency. Iron is one of the key elements in chlorophyll. Thus, iron deficiency is a major cause of chlorosis. Furthermore, chlorosis can also occur as a result of disease, herbicide injury, poor water drainage, damaged roots, high alkalinity, compacted soil, etc. However, the reasons for chlorosis may vary from plant species to species. For example, some plants grow well inalkaline soils,但他们也可能显示萎黄病由于其他一些reason.

Chlorosis can be overcome by supplementing the plants with adequate amounts of nutrients via fertilization. Moreover, diagnosing the specific reason for chlorosis and treating it in accordance is the best solution for chlorosis.

What is Necrosis?

在植物中，坏死是植物细胞或组织的死亡。坏死是由于受伤或疾病而发生的。此外，坏死是由于营养缺乏而导致的。坏死区域显示为棕色斑点。坏死可能发生在叶子，茎，根，叶边缘，静脉等上。与氯化不同，坏死是不可逆的。

Viral infections often lead to necrosis in plants since viruses use plant cells to replicate, and they often come out by lysing the host cell. Tobacco necrosis virus affects tobacco plants causing necrosis. Similarly, Soybean vein necrosis virus affects the vascular system, while cymbidium mosaic virus affects orchid flowers. Bacteria and fungi also cause necrosis in plants. Some bacteria degrade cell walls of plant cells, leading to cell death and necrosis. Some fungi attack the vascular system of plants and cause different diseases likeanthracnose这导致植物坏死。

What are the Similarities Between Chlorosis and Necrosis?

• Chlorosis and necrosis are two types of symptoms shown by the plants.
• One of the major reasons for chlorosis and necrosis is a nutrient deficiency.
• 同样，两者都可能由于病毒感染而发生。

氯化和坏死之间有什么区别？

Chlorosis refers to yellowing of green colour plant parts, while necrosis refers to the death of plant cells and tissues. So, this is the key difference between chlorosis and necrosis. Chlorosis appears as yellow spots, while necrosis appears as a brown or black spots or areas. Therefore, another difference between chlorosis and necrosis is their reversal; severe chlorosis cannot be reversed. But, if identified early, it is reversible. However, necrosis is not reversible.

摘要 - 绿化与坏死

绿化和坏死是植物中的两个明显症状。氯化是由于缺乏叶绿素而导致叶组织的黄色，而坏死是植物细胞或组织的死亡。因此，这是绿化和坏死之间的关键区别。氯化为黄色斑点，而坏死在叶子上出现棕色或黑色斑点。
