Differences in macronutrient uptake by apple rootstocks M9, M27 and MM106

Popis výsledku v původním jazyce

Rootstocks differ in their uptake of macro- and micro-nutrients. The aim of this study was to determine the uptake of macronutrients by the apple rootstocks M9, M27 and MM 106, which are mostly used in fruit production in the Czech Republic. One-year-old rootstocks were cultivated in soil during winter. At the beginning of the vegetative growth, plants were transferred to the cultivation room into a hydroponic solution with a photoperiod of 16 h light/8 h dark and 23°C day/17°C night temperature. Nutrient uptake (NO3-, NH4+, H2PO4-, K+, Mg2+) was studied during flowering. After acclimation, plants were placed into a solution of known concentration of nutrients. The rates of nutrient uptake, expressed as microgram of nutrient absorbed per hour per rootstock, were determined from the concentration changes of the solution, during the experiment. Two N sources were tested, either NO3- or NH4+. Rootstocks absorbed ammonium ions from the nutrient solution faster than nitrate. M9 took up nitrogen from the two supplied N forms more evenly; MM106 was the slowest rootstock in absorbing nitrate, but was the fastest in absorbing ammonium ions. Tested rootstocks absorbed phosphorus faster in the presence of nitrate than in the presence of ammonium. The uptake of potassium and magnesium by M27 was faster than the M9 and MM106 rootstocks in the presence of nitrate. The presence of the ammonium ions can cause inhibition of cations intake and in this experiment only their efflux was observed.
