Özet

The effects of controlled hydration treatments on seed storage longevity of aubergine (Solanum melongena L.) seeds harvested 45, 50, 55, and 60 days after anthesis (daa) in 1999 and 2000, were studied. Treated and control seeds were stored at 30 degreesC with 12% moisture content and sampled monthly for up to 180 days. Longevity was assessed by changes in P-50 (half-viability period) and regression coefficients of the survival curves following probit analysis. The treatments extended P-50 values between 19 and 65 days longer than the control, depending on the seed lot. Controlled hydration also substantially decreased life span of seeds in time (regression coefficient). The maximum advantage was obtained in 45 and 60 daa in 1999 and 2000 during development, respectively. Results showed that controlled hydration treatment could be used to prolong the storage longevity of aubergine seed lots from different stages of development.
