When it comes to the growth and development of plants, environmental factors play a vital role. Among them, climate, soil, and gas components affect the physiological process of plants.
Avena Sativa is a common crop that is widely planted around the world. It is an important food crop that is also used as feed and green fertilizer.The leaves of nude oats are rich in carotene, which is a very beneficial compound that is very beneficial to human health. Carotenoids play an important role in antioxidant and photosynthesis in plants.
Hydrogen sulfide (H2S) is a gas with a special smell, which exists in nature. Although hydrogen sulfide is toxic at high concentrations, in an appropriate amount, it can also have a positive impact on the growth and development of plants. Some studies have shown that appropriate amounts of hydrogen sulfide can promote the growth of plants, increase yield and increase resistance.
Regarding the effects of hydrogen sulfide on naked oat carotene composition, there are relatively few current research. However, some related studies have given some interesting results. For example, a study found that under the appropriate amount of hydrogen sulfide, the content of carotene -like in naked oats’ blades increased significantly.This indicates that hydrogen sulfide may promote the synthesis or stability of carotene through some mechanism.
In addition, some studies have found that hydrogen sulfide can regulate the synthesis of carotene in plants. The synthesis of carotene is a complex process that involves the participation of multiple enzymes. Hydrogen sulfide may affect the synthesis of carotene by regulating the activity or gene expression of these enzymes. However, specific mechanisms need further research to reveal.
In addition, hydrogen sulfide can also affect the composition of carotene by regulating the photosynthesis of plants. Photosynthesis is one of the most important physiological processes in plants,It is the main source of carotene synthesis. Hydrogen sulfide may affect the synthesis and accumulation of carotene by regulating the rate and efficiency of the optical synthesis.
In general, the current research shows that appropriate amounts of hydrogen sulfide can promote the synthesis and accumulation of carotene in naked oats. However, specific mechanisms need further research to reveal. The results of these studies are of great significance to understanding the growth and development of plants, as well as optimizing the yield and quality of cash. It is hoped that future research can further reveal the effects of hydrogen sulfide on naked oat carotene composition, and provide more scientific basis for agricultural production.
Soil saline is a global issue that affects agricultural production and the environment. Carotene is a fat -soluble hydrocarbon compound synthesized by the gonadotropin pathway.
As an important part of the optical membrane of the plant chloroplast, not only does it absorb and transmit optical energy in photosynthesis. They also eliminated triterpenin, monocooloral oxygen and supersonic free radicals, consumed the excess light energy absorbed by chloroplasts, and protected the damage caused by strong light. Carotenoids are also a precursor that is synthetic in plants.
The accumulation of carotenoids is not only related to the color of fruits and vegetables, but also closely related to the salt resistance of plants. Studies have shown that under salt stress, the level of carotene -like in eggplant seedlings is reduced. As the concentration of salt stress increases, the content of carotene in the Coptis chinensis decreases, and then increases.It can be seen that the accumulation of carotene in plants is particularly critical to the adaptation of plants to salinity. It is of great significance to understand and adjust the composition of carotene under salt coercion.
Hydrogen sulfide is a third gas signal molecule found in the organism. It is regulated by various physiological processes such as seed germination, root development, and air pores, including drought, low temperature, and alleviating heavy metal stress damage. Studies have shown that endogenous hydrogen sulfide enhances the salt resistance of purple magpies by combining oxidation balance and K+overflowing suppression.
External hydrogen sulfide can maintain NA+/K+balance, and relieve cucumber salt stress by adjusting hydrogen sulfide metabolism and oxidation stress. Further research shows that the expression of exogenous hydrogenation by adjusting NA+/H+reverse transport protein and H+-TpaSe genes maintains NA+/K+balance of barley, and is confirmed to adjust the signal pathway of non-selective cations and salt sensitive protein 1 (SOS1) signal pathways. Under the coercion of low NA+level of wheat, hydrogen sulfide maintains the oxidation and reduction of rice and the balance of mineral ions.
Studies have shown that exogenous hydrogen sulfide can increase the carotene content of tomato seedlings under salt stress. However, whether the hydrogen sulfide is involved in the adjustment of plant carotene components under the hybrid coercion of saline and alkali, no report has been seen so far.
The content of corn yellow quality in nude oats is higher than the content of its derivative ester. The corn yellow two-based mustard acid and corn yellow quality February cinnamonic acid content is high, while corn yellow quality-laurel acid-palm acid-palm acid-palm acid-palm acid The content of salt and corn yellow-laurel acid-meatmer acid salt is low.
Compared with the control, salicylic acid treatment has significantly increased the content of corn yellow, corn yellow di aggregates and corn yellow pupa. Significant differences. Compared with SA processing, the content of corn yellow quality, corn yellow pornography and corn yellow cinnamate in SA+NA HS are significantly reduced,However, the content of corn yellow glyconite and corn yellow cinnamonate is not significant.
Compared with SA processing, the content of corn yellow quality and derivatives of SA+HA have decreased to varying degrees. Compared with SA+NA HS+HA, there is no significant difference in corn yellow quality and its derivative ester. Compared with the control, the content of corn yellow quality treated alone has increased significantly, while the content of corn pornography February cinnamate and corn yellow cinnamate cumamate is significantly reduced, but the corn yellow diocylonate and the ester and the corn yellow The content of corn yellow cinnamate palmate is not significant.
单独HA处理的玉米黄质-月桂酸-肉豆蔻酸酯的含量显著低于对照，而玉米黄质、玉米黄质二聚体、玉米黄质二月桂酸酯和玉米黄质-月桂酸-棕榈 There is no significant difference in the content of acid ester.
Soil salt has many adverse effects on plants, such as penetration stress, ionic toxicity, lack of nutrients, oxidation stress, etc. And growth and changes are the most intuitive manifestations of plants after saline coercion.
Studies have shown that spraying Na HS can significantly alleviate the inhibitory effect of mixed saline and alkali stress on the growth of pyrometer. The relief effect of spraying NA HS is partially reversed after adding hydrogen sulfide synthetic inhibitors. It shows that hydrogen sulfide participates in the regulation of salt -alkali stress response, which can enhance the adaptability of cymbal wheat to saline coercion.
This is consistent with the result of the use of hydrogen sulfide to tomato to reduce the degree of plant growth suppression under NA CL coercion. There may be many mechanisms for hydrogen sulfide to alleviate salt -alkali coercion and inhibit plant growth. There may be many mechanisms for plant growth.However, hydrogen sulfide, as a downstream signal of the body, can trigger the growth of cells to stimulate cell growth, which may be one of the important reasons.
