Influence of nutrient solution concentration and composition on vegetative properties of tomato grafted transplants
The aim of the study was to determine the influence of nutrient solution concentrations and composition (NS) on the vegetative properties of tomato transplants. The experiment was set up with tomato, cultivar ‘Belle F1’, non-grafted (B), self-grafted (B/B) and grafted onto rootstock Arnold (B/A) and He-Man (B/H). Nutrient solution for transplant production (composition: 1.25 mM NH4+, 12.71 mM NO3-, 1.25 mM H2PO4-, 8.75 mM K+, 2 mM Mg2+, 4.25 Ca2+, 1.75 mM SO42-, 15 μM Fe2+, 10 μM Mn2+, 5 μM Zn2+, 0.5 μM Mo+, 0.75 μM Cu2+ and 30 μM B+) were applied in three concentrations: EC 3, EC 6 dSm-1 and EC 3 NS + 3 NaCl (EC 6 NaCl) in which a NaCl solution was added to the EC 3 NS to achieve target EC (6 dSm-1). The height (19.7 cm) and leaves number (6.7 leaves) were lower in non-grafted transplants compared to grafted ones. Transplants treated with EC 3 dSm-1 had significantly larger stem diameter than transplant treated with EC 6 NaCl dSm-1. Non-grafted transplant had significantly smaller stem diameter than grafted ones. The highest chlorophyll content index was recorded by transplant treated with EC 6 dSm-1 (36.4). The transplants leaf area was influenced by both factors. Transplants B/H had a larger leaf area than B transplants regardless of which NS were applied. The leaves thickest were recorded on the transplants treated with EC 6 NaCl (365 cm2g-1). Grafted transplants better alleviate salts stress than non-grafted transplants, while tolerance to the salt type depends on the used rootstock.
