The interaction of rootstocks, water and soil humectants and young apple tree growth

Аннотация

Young apple trees that are planted in areas with limited water resources face challenges in their early growth stages. Insufficient intake of moisture often stunts the growth of the young tree and impacts its subsequent growth. In this study, we observed the interaction of semi-vigorous Marubakaido (Ma) (Malus prunifolia „Ringo‟) and dwarfing Jm7 („Marubakaido‟ × M.9) rootstocks, water treatments (50% and 70% soil water content) and soil treatments (water retention substances) on young „Miyabi Fuji‟ apple trees and how this interaction impacts their growth under dry climactic conditions. The development of shoots, stems and roots was analyzed. The results showed that the interaction of rootstock and water and soil treatments had a significant impact on total shoot length (p < 0.01), as did the interaction of rootstock and soil treatment on the length of the top three shoots (p< 0.05) and trunk fresh weight (p < 0.05). In addition, it was found that the interaction of water and soil treatments impacted shoot fresh weight (p < 0.05). This study revealed that the growth of young apple trees in areas with limited water resources can be aided by providing a 70% and 50% saturation of water and soil retention treatments for young trees that have been grafted onto semi-vigorous Ma and dwarfing Jm7 rootstocks. Growers in these areas should think about which rootstock to use, what soil water retention treatments that can be introduced into the soil as well the amount of water that should be applied.
