| Abstract:
The longevity of the yellow passion fruit has been reduced due to the premature death of the plants which may occur at any stage of the plant development ranging from 3 months to 3 years of age. In most cases the exact cause of death has not been clarified yet. Since 1977 we have observed the behavior of several different species, by using a contamined planting bed (*). These observations allowed us to come to the following conclusions about the susceptibility of different Passiflora species: Susceptible to dieback: P. serrato digitata; P. coccinea; P. cincinatti; P. incarnata. Tolerant to dieback: P. caerulea; P. macrocarpa; P. alata. Resistant to dieback: P. giberti. Presently, we have started taking records on the yield and development of yellow passion fruit grafted onto these different species. | |
