Abstract
An experiment was conducted at the field of Horticulture and Landscape Design Department, College of Agriculture& Forestry,during the growing season 2010-2011. To investigate the effect of foliar spraying of seaweed extract (Algamix) and low temperature (3±1) °C on flowering and plant yield parameters of two strawberry cultivars ( Fragaria X ananassa Duch.) .Transplants of two strawberry cultivars (Hapil and Kaiser's samling) were exposed to three periods (0 , 15 and 30 days) of low temperature (3±1) °C and three concentrations ( 0 , 1.5and 3.0 cm3/L) of seaweed extract ( Algamix) applied as a foliar spray on plants of strawberry cultivars. The experimental design was a randomize complete block design (RCBD) with three replicates . The obtained results could be summarized as follows: * Hapil cultivar was superior in yield per plant and pollen grain validity as compared with kaiser's samling variety. * Spraying of Algamaix extract at both concentrations 1.5 & 3 cm3/L increased plant yield significantly, while only conc. of 1.5cm caused a significant increase in the length of flowering period as compared with 3.0 cm3/L concentration treatment, which caused a significant increase in both average number of days from planting to first flower appearance and number of flowers per plant significantly . *Exposure of strawberry transplants to low temperature increased yield per plant significantly and induce flowering in both cultivars. Treatment of 15 days duration of cold storage significantly increased number of flowers per plant as compared with the effect of 30 days duration treatment
