Physiological Potencial of Seeds of Physalis Peruviana L. Depending on Different Managements

Abstract

In the process of agricultural production of Cape Gooseberry, the obtaining of new plants occurs commercially by the sexual route, being the seed the main form. The physiological potential of seeds may be influenced by some cultural tracts. This study aimed to evaluate the physiological potential of Physalis peruviana L. Seeds cultivated in different stoning, pruning and harvest time systems. The experiment was carried out in Londrina PR, using a completely randomized design, in a 5x4x2 factorial scheme, with four replications, containing five harvest times of the fruits (117, 124, 130, 137 and 141 days after transplanting), Four Tutoring systems (“UEL tutoring”, “adaptive” V “tutoring”, no tutoring and “vertical tutoring”) and two types of pruning (with and without Desbrota). For the physiological potential of the seeds, first count germination, germination, germination speed index, seedling length and dry mass were performed. Data were subjected to analysis of normality and homogeneity and compared by Tukey’s tests for qualitative variables, and by linear regression tests for quantitative variables, at a 5% probability level. It was found that the desbrotte, stoning and harvesting of fruits made at 117 days after transplanting positively influenced the physiological potential of seeds of physalis peruviana L. The adapted inverted V-tutoring presented Higher value for seedling dry matter.
