Qualidade de sementes de Physalis peruviana L. produzidas em diferentes níveis salinos.

Abstract

Physalis peruviana L. is a fruit-vegetable, belonging to the Solanaceae family, of great nutritional and economic value, it is incorporated into the framework of small fruits in Brazil.which is being incorporated into the framework of small fruits in Brazi l. Because it is a rustic plant and good adapted to the different environmental conditions, it is an excellent alternative for small and medium producers. Its propagation occurs mainly by seeds, which are still difficult to access in the country and there are no reports regarding the production in our conditions. The objective of this study was to evaluate the quality of seeds of Physalis peruviana L. produced at different saline levels of irrigation water. The work was developed in the Laboratory of Analysis of Seeds and Seedlings (LABASEM) in a protected environment of the Agro-Food Science and Technology Center, Federal University of Campina Grande, Campus de Pombal, PB, in a completely randomized design. The seeds used were produced under different saline levels (0.3, 1.2, 2.1 and 3.0 dS m-1) in cultivation under protected environment conditions, in the municipality of São Domingos – PB. The physical and physiological quality was evaluated by determining the degree of moisture and the weight of one thousand seeds, germination test, first germination count, germination speed index, radicle length, electrical conductivity, emergency, and emergency speed index. The physical and physiological quality of P. peruviana seeds was not affected by the increase of saline levels up to 3.0 dS m-1 during their production.
