Photosynthetic Apparatus Of Cotton Leaf: Activity Under Harmful Factors And Inductors

Аннотация

The article deals with the effect of a typical representative of sucking pests on the photosynthetic apparatus of the plant - the mite, and the effectiveness of measuring photosynthetic activity using a highly sensitive fluorescent method. Alternatively, photosynthetic apparatus activity was measured using the fluorescent method, and it was used to assess the degree of pest infestation of the plant, especially mites, and to determine the plant’s resistance after red light treatment. When damaged by mites, the long-wave native forms of cotton chlorophyll are disrupted and the electron-transport chain of the photosynthetic apparatus is blocked. As a result of QN treatment of seeds, the distribution of algae in plants decreases, while the activity of photosynthetic apparatus, on the contrary, increases. This means that phyto-chrome photo conversion has a specific effect on the photosynthetic apparatus.
