【 摘 要 】

Vegetable grafting is an alternative in crop production systems under adverse conditions. The most important rootstocks are Cucurbita and Lagenaria in the cultivation of watermelon. The Lagenaria specie is distributed in Mexico, however, the use of na-tives materials as rootstock is limited or non-existent, so that this investigation was to evaluate and select the best combinations of native rootstock Lagenaria siceraria and two watermelon varieties. The experimental design utilized was completely randomized with factorial arrangement 2x7 and three replicates per treatment. The variables evaluated were early production, total yield, pulp firmness, pulp proportion offruit and total soluble solids. The production precocity was greatest with variety 2800 exceeding by 12.35% to Sangría, and in the case of rootstocks, the general trend was higher precocity with respect to control plants. The yield was favored by graft mainly combinations L43 and L56. The proportion of pulp was higher in 2800 compared with Sangría, whereas no significant effects observed by combination of graft. The total soluble solids was a parameter with significant effects on the interaction between variety and combining graft, registering higher increases in this variable in combinations of rootstocks with variety Sangría. The rootstocks more impact on precocity, yield and fruit quality were L43 and L50, which can be considered for subsequent improvement programs.
