| Sumario: | Salinization of rooting media in intensive production as a consequence of the use of irrigation water with high electrical conductivity has increased in greenhouse environments. One strategy to mitigate the effect of salts on crops is the use of plants grafted on a rootstock that tolerates this abiotic stress. Melon (Cucumis melo L.) is usually grafted using as rootstock different species of the genus Cucumis or Cucurbita, interspecific hybrids of the genus Cucurbita, or with Lagenaria siceraria. In this work, three experiments were conducted to quantify the pattern of aerial and root biomass accumulation of seedlings of Cucurbita maxima Duch. x Cucurbita moschata Duch. Four treatments were carried out using nutrient solutions of different salinity (0.84, 4.00, 6.00 and 8.00 dS m-1). The increase in the amount of salts supplied at the end of the experiments in the higher salinity treatments resulted in a lower accumulation of dry matter in the plants. Growth analysis using the leaf weight ratio (RPF), absolute growth rate (TAC), relative plant growth rate (ICRF) and leaf relative growth rate (ICRP) corroborated this decrease. The results obtained indicate that it would not be advisable to use this hybrid as a rootstock for seedling production under saline conditions. |
