Effect of Seed Production Environment and Time of Harvest on Tomato (Lycopersicon esculentum) Seedling Growth

Ibrahim Demir, Anna M. Ashirov and Kazim Mavi

Abstract:
This study was carried out to find out the effects of two growing seasons and harvest time on seedling growth in tomato. Seeds were harvested between 40, 45, 50, 55, 60, 70, 80 and 90 DAA (days after anthesis) in spring and 45, 50, 55, 60, 70, 80, 90, 100 and 115 DAA in autumn season from hybrid tomato plants grown under glasshouse. Maximum seed weight occurred at 50 DAA in spring but went up to 80 DAA in autumn season. Maximum seedling emergence took place at 60 DAA in spring as 89% but 115 DAA as 90% in autumn. The highest seedling fresh and dry weights were also observed at the same harvests. As seeds matured the fewer seeds were germinated but unable to emerge in the compost. Advancement in seed maturation not only increased seedlings fresh and dry weight but also seedling uniformity (R2 = 0.75, R2 = 0.69) measured through coefficient of variation (CV). Fast emergence (lower mean time to emerge) resulted in the higher seedling fresh weight (R2 = 0.80, R2 = 0.84). Occurrence of maximum seedling quality in tomato was influenced by the growing environment. Low greenhouse temperatures in autumn delay occurrence of the maximum seedling growth up to 115 DAA. While, it can be obtained from seeds harvested at 60 DAA in spring.
