Changes in Hardseededness and Other Characteristics of Trifolium Resupinatum Var. Typicum Fiori Et Paol. (Fabaceae) Seeds Stored in Uncontrolled Conditions

Abstract

This research was carried out at Analyses Laboratory of field Crops Department in Agricultural Faculty, Namik Kemal University, Tekirdag, Turkey. The germination experiments, which were set up as completely randomized blocks with three replicates, were performed from seed harvest to end in 15 day intervals. In the experiment, the hardseededness (%), dead seed (%), germination speed (%) and vigor (%) ratios in Trifolium resupinatum var. typicum Fiori et PaoL which has different seed color such as yellow, red, green and mixed were determined and their variations in a year were examined. It was determined that seed color and time after harvest could affect all characteristics found out. While the highest hardseededness was determining green seeds (68.4%), the highest dead seed ratio was 2.4% in red seeds. The germination speed was 31.0% in yellow seed and their vigor was found high (38.9%). While the highest hard seed ratio was found in 10th (94.3%) germination period, the highest dead seed ratio was 3.1% in 18th germination period. The highest germination speed and vigor were counted in 21st -26th period and the lowest values were obtained from 10th period.
