Evaluación del prendimiento de dos variedades de ucurbitáceas en tres portainjertos para producir plantas de pepino (Cucumis sativus L.).

Abstract

Vegetables are of great economic interest due to their high production and market demand; such as cucumber (Cucumis sativus L.) has therefore generated an excessive use of agrochemicals that enhance production and reduce pathogens, however, these alternatives drastically affect the environment and human health; Thus, grafting in vegetables is a clean alternative to integrate into production systems. The following research aimed to evaluate three types of rootstock Sambo (Cucurbita ficifolia), Zapallo Castellano (Cucurbita maxima), Commercial pattern (Kickoff) in two varieties cucumber (Cusumis sativus var. Mydas) and (Cusumis sativus var. Lisboa). The experiment was carried out with a 3x2 factorial arrangement within a completely randomized design and three replications for each treatment. Variables such as graft diameter, graft length, number of leaves per graft, percentage of grafting were evaluated, the data were subjected to an analysis of variance and were examined using Tukey's significance tests at 1% using the Infostat statistical program. Regarding the variable of taking of the grafts, there were no statistical differences, all the treatments were higher than 95%, the rootstocks P1 (Sambo) and P2 (Zapallo Castellano) were the ones with the highest number of leaves per graft with means of 2.61 and 2.33 leaves per graft, in terms of graft diameter, the treatment that was superior is T2 (P1V2) describes the Sambo pattern factors with Lisbon stem with an average of 0.29 cm and for the graft length variable the P1 pattern (Sambo ) and P3 (Kickoff) were grouped in range A, being the longest with 4.19 and 3.94 cm, respectively
