Seed Vigour Evaluation of Cucumber (Cucumis sativus L.) Seeds in Relation to Seedling Emergence

Ibrahim Demir and Kazim Mavi

The seedling emergence of 16 commercial seed lots (7 in 2005 and 9 in 2006) of cucumber (Cucumis sativus L.) were compared at low temperature (LTE), mechanical stress (MSE, 8 cm sowing) and salt stress (SSE, 200 mM NaCl) plantings. The emergence percentage ranged between 29-76% for LTE, 46-86%, for MSE and 59-92% in 2005 and 35-86% at LTE, 28-83% at MSE, 54-93% at SSE in 2006. The radicle emergence of the lots was determined after Controlled Deterioration (CD) at 45, °C with 20 or 24% moisture content for 48, 72, 96, 120, 144 h. The accelerated ageing test was also conducted at the same temperature and durations in both years. Germination after large number of combinations of CD and AA was (p<0.05) correlated with LTE, MSE and SSE. Initial laboratory germination was significantly (p<0.05) related to LTE, MSE and SSE in 2005 but not in 2006 (p>0.05). The optimum CD conditions of 48 h and 20% mc at 45,°C and AA conditions of 96 h at 45, °C are suggested as a successful vigour test conditions for cucumber seeds.
