Title : INFLUENCE OF SOME APPLE ROOTSTOCKS GRAFTED BY GOLDEN DELICIOUS ON N, P, AND K MINERAL UPTAKE UNDER RAINFED CONDITIONS
Abstract : The study was carried out at the agricultural scientific research center in Sweida- GCSAR, to evaluate the influence of apple rootstocks on N, P and K minerals uptake in the vegetative parts during growth season. Two apple rootstocks; vegetative rootstock MM106 and seedling rootstock Malus domestica Borkh. Which grafted by Golden delicious cultivar were studied. The results showed that MM106 rootstock revealed highest significant accumulation of Nitrogen in shoots in May (1.69%), while the seedling rootstock revealed the highest accumulation of nitrogen in leaves in May (2.81%).The highest fruit concentration of N was in June for the two rootstocks. Likewise, phosphorous content in shoots was the highest in June for the two rootstock (0.214% and 0.213% for MM106 and seedling rootstock, respectively), and the Phosphorous concentration of leaves was the highest in May on the seedling rootstock than MM106 rootstock (0.23 and 0.22%, respectively), fruits significantly revealed the highest P content in August for the two rootstocks which was 0.15% in seedling rootstock and 0.18% in MM106. The K content was the highest for shoots and leaves in May for the two rootstocks, and seedling rootstock revealed higher concentration than MM106. Likewise, fruits significantly revealed the highest K content in August in trees grafted on seedling rootstock (1.15%). Consequently, this investigation showed different responses of rootstocks for uptake and accumulation of N, P and K mineral elements during growth season which lead to establish the correct strategy for fertilization management according to the planted rootstock under rainfed conditions.
