Development of yellow passion fruit seedlings grafted onto four rootstocks of Passiflora species
Yellow passion fruit (Passiflora edulis f. flavicarpa) is one of the main fruit species in the Neotropical region and Colombia is one of its main producers with about 165 893 tons/year. Despite this, the crop is affected by multiple phytosanitary problems, such as fusariosis caused by Fusarium solani f. sp. passiflorae (passion fruit collar rot), which can cause considerable crop losses. The objective of this research was to estimate the effect of four Passiflora rootstocks (P. alata, P. maliformis, P. quadrangularis, and P. edulis f. edulis) tolerant to fusariosis, on the vegetative growth of the yellow passion fruit seedlings. The study was carried out at the Agrosavia experimental station in Palmira, Valle del Cauca (Colombia), under a completely randomized design consisting of six treatments and six repetitions. Data were subjected to multiple range tests and Dunnett’s multiple comparison test of means (p < 0.05). It was found that the evaluated rootstocks presented 100 % grafting and compatibility > 1 (except self-grafted yellow passion fruit, 0.85). Likewise, grafted seedlings reached field conditions at 15 cm height and five leaves between 30 to 60 days after grafting. Most of the rootstocks evaluated showed a reduction of approximately 35 % in plant height, number of internodes, and number of leaves, compared to non-grafted yellow passion fruit. Therefore, it is necessary to perform a comprehensive assessment to select which rootstocks are the best to mitigate this problem in yellow passion fruit orchards.
