Storage potential of the eggplant (Solanum Melongena L.) collection accessions for ex situ conservation in a plant gene bank [Articol]

Abstract

To determine the storage potential (SP) of samples from the eggplant collection in the gene bank's active collections, two tests were used: the accelerated seed aging test ( AA ) and the electrical conductivity test (EC). After conducting the AA test to the seeds, which was conducted at an elevated air temperature (45-47°C) and elevated humidity (90-100%), the morphophysiological and biochemical parameters of the seeds and seedlings were determined. Based on the set of parameters studied, the eggplant samples were divided into two groups: Group 1 - with high seed viability (genotypes Sucleischii, Varatic, Rada, Almaz, Acvamarin, Laura), Group 2 - with average seed viability (Magda, Belaia Lilia, Flower Goddess, Black Beauty genotypes). Determining the storage potential of seeds enables us to predict the storage life of eggplant collection samples in a plant gene bank during ex situ conservation, as well as to make recommendations on seed reproduction times.
