Morphological characterization of fruits, seeds and germination of Passiflora cristalina Vanderpl. & Zappi
The study aimed to characterize the fruits and seeds of Passiflora cristalina Vanderpl. & Zappi. as well as assessing the influence of mucilage fermentation on seed germination and initial seedling growth, this study was carried out on native populations in the municipality of Alta Floresta, MT. The fruits were collected in the final stage of maturation and the length of the fruit, width of the fruit were measured, as well as the weight of each fruit and the weight of the seed was also evaluated. The morphometry of P. cristalina seeds was obtained from seeds chosen randomly from all the seeds of the fruits collected from the species, and the length and width of the seed were measured. To evaluate the influence of mucilage fermentation on seed germination, an experiment was carried out with five treatments, for the first treatment (T1) the removal of the aryl was done with friction in a plastic mesh sieve, the other treatments consisted of seeds placed together with the pulp in a Petri dish, varying only by the fermentation time: treatment 2 (T2- 48 h), treatment 3 (T3–72 h), treatment (T4-96 h) and treatment (T5-120 h). The collected data were discovered through analysis of variance. Then, subject to the Tukey test at 5% probability by the SISVAR statistical program. The differences found between the relative and maximum values of the characteristics analyzed in this study, represent an indication of high population genetic variability, and may allow an exploration of parameters seeking to maintain areas with populations of the species, in addition to assisting the breeder to perform the introgression favorable alleles found in wild species, such as disease resistance, self-compatibility and androgen reduction, through interspecific crossing. P. cristalina had a lower emergence rate, as well as other wild species.
