Özet

This study was carried out to determine the effects of different irrigation intervals (SA(1): 2-d, SA(2): 4-d, SA(3) 6-d) and water amounts (S-1:T-r x 1.50, S-2:T(r)x1.25, S-3:T(r)x1.00, S-4:T(r)x0.75, S-5:T-r x0.50, S-6:T(r)x0.25) on quality parameters of chrysanthemum grown in the greenhouse in 2011. The spray chrysanthemum (Chrysanthemum morifolium Ramat cv. 'Bacardi') plant was used as plant material in this study. Different ratios of the potential evapotranspiration (T-r), calculated using radiation values in outside the greenhouse, was applied as irrigation water. The irrigation water amounts applied to the experimental treatments ranged from 192.1 to 469.4 mm, and seasonal evapotranspiration (Et-a) measured from 300.9 to 510.9 mm. Different irrigation water amounts and irrigation intervals had statistically significant effects on flower stem length, stem diameter, the number of secondary lateral branches, the number of flowers, stem weight, leaf area index, vase life root length of chrysanthemum (P<0.05). In the study, flower stem length, stem weight and stem diameter varied between 81.72-40.04 cm, 140.70-19.31 g and 8.01-4.00 mm, respectively. The best quality chrysanthemums were obtained from SA(2)S(2) on which about 1.25 times of the potential evapotranspiration calculated in two day intervals was selected as optimum irrigation program.
