Chloroplast, chlorophyll plant Photosynthesis workshop The plant is a green plant that carries out photosynthesis and produces organic matter. The leaves are the workshop. Chloroplasts and chlorophyll are energy converters that convert light energy into chemical energy and produce organic matter. Area and chlorophyll are the other major factors affecting photosynthetic yield. The leaf area can be measured using a portable leaf area meter. Chlorophyll content can be measured using the chlorophyll meter as a professional instrument for measuring chlorophyll. Here's a simple look at how the two affect photosynthetic activity. Reaction speed.
The impact of leaf area is reflected in two aspects:
1. Leaf area refers to the number of lines: The size of the leaf area is represented by the leaf area index. Generally, under open field conditions, when the leaf area index of the plant is less than 3, the photosynthetic yield decreases with the reduction of the leaf area index. If the leaf area index is greater than 5, due to the mutual shade of the leaves, the lighting conditions deteriorate, and the photosynthetic yield instead increases with leaf area. The index decreases and increases. A reasonable leaf area index is 3--5. Therefore, the positive leaf area is only positively related to the yield. In the production practice, we must not blindly expand the leaf area so as to avoid waste, consume water and fertilizer, deteriorate the lighting conditions, and cause a decline in production.
2. Leaf age and leaf dynamics: The photosynthetic capacity of the young leaves of the crop is very weak. When fully grown into strong leaves, the photosynthetic capacity is the strongest, and after the leaves are senescent, the photosynthetic capacity rapidly declines. Therefore, in the management of greenhouses, the light, temperature, fertilizer and water conditions should be met as early as possible to promote its early-onset leaves, fast-growing leaves, expand the leaf area as soon as possible to increase production. However, as the crop grows, the leaf area index expands and mutual shading gradually increases. Therefore, when the leaf area index reaches 2.5, it should also be controlled to continue to grow, promptly eradicate shoots, shoots, remove the senescent leaves of the base, increase the proportion of young leaves, reduce consumption, improve lighting conditions, and maintain strong photosynthesis.
Effects of chlorophyll on photosynthesis of plants: Chlorophyll content in leaves is closely related to photosynthetic intensity. The photosynthetic intensity of leaves with dark green leaves and high chlorophyll content was significantly higher than that of leaves with light leaf color and low chlorophyll content, sometimes differing by 2-3 times. Chlorophyll, like other organic substances in plants, is constantly updated. For example, the chlorophyll content of spinach can be updated more than 95% after 72 hours.
