Gisela No. 17 rootstock seedlings, as a medium for grafting Shawang cherry seedlings, have incomparable advantages. It not only provides a strong vitality for cherry seedlings, but also plays a significant role in stress resistance.
When we talk about stress resistance, we first need to understand what stress resistance is. Stress resistance refers to the ability of plants to grow, develop and reproduce normally in the face of adverse conditions such as drought, high temperature, salinity, etc. Gisela No. 17 rootstock seedlings, with their unique growth characteristics and physiological mechanisms, provide strong stress resistance support for Shawang cherry seedlings.
Under drought conditions, Gisela 17 rootstock seedlings are able to absorb water from deep soils through well-developed root systems and maintain the normal metabolism of the tree. At the same time, the water regulation mechanism in the body can help the sand king cherry seedlings reduce water consumption and enhance drought tolerance.
In the high temperature environment, Gisela 17 rootstock seedlings have high thermal stability, which can provide effective protection for Shawang cherry seedlings. By regulating the temperature and humidity of the tree, it reduces the damage of high temperature to the saplings, so that the sand king cherry saplings can still maintain high growth vitality in the hot season.
In the face of saline-alkali soil stress, Gisela 17 rootstock seedlings showed extraordinary adaptability. Its root system can secrete some organic acids, which help to reduce the pH value of the soil and reduce the toxic effect of salinity on seedlings. In addition, it can also improve the growth performance of sand king cherry seedlings in saline-alkali land by increasing the absorption and utilization efficiency of nutrients by the tree.
In conclusion, Gisela 17 rootstock seedlings had a significant effect in enhancing the stress resistance of Shawang cherry seedlings. By grafting the Gisela 17 rootstock seedlings, we can better cope with various environmental challenges and ensure the healthy growth of the Shawang cherry seedlings and bring a more fruitful harvest to the growers.
