ARAMENDIZ-TATIS, H; CARDONA-AYALA, C  e  ALZATE-ROMAN, K. Electrical conductivity test in the evaluation of physiological quality in seeds of eggplant (Solanum melongena L.). Scientia Agropecuaria [online]. 2017, vol.8, n.3, pp.225-231. ISSN 2077-9917.  http://dx.doi.org/10.17268/sci.agropecu.2017.03.05.

The objective was to evaluate the effect of seed number and imbibition time through the electrical conductivity test, to know the physiological potential of eggplant seeds. We used the completely randomized design with factorial arrangement 2x2x5 (varieties CO015 and CO029), (seed quantities of 50 and 100) and (imbibition times of 2, 4, 6, 8 and 10 hours); With four replicates. The results of the physiological quality of the seeds for the initial conditions yielded germination percentages of 81.20 and 98.30 for seven and 14 days and indexes of emergency speed with values of 15.76 and 16.64 for the cultivars CO029 and CO015, reflecting their low metabolic activity in storage. As regards electrical conductivity, the number of seeds for application is 100 with an imbibition time of six hours. Regression analysis yielded a linear response for cultivar CO029 with electrolyte releases of 0.32 and 0.48 μS cm-1 g-1 per hour, respectively for 50 and 100 seeds; While the cultivar CO015, cubic response with linear response of 3.40 and 4.25 μS cm-1 g-1 per hour and reductions of -0.55 and -0.62 μS cm-1 g-1 per hour, reflecting the greater deterioration of the seeds to amounts of 50 and 100, respectively
