Abstract

ATANASSOVA, B., I. FILIPOVA and V. ALEXIEVA, 2004. Effect of plant growth regulators Alar, MEIA and Paclobutrazole on the phenophase of flowering and some ornamental parameters of mini-carnation (D. caryophyllus f. spray Hort.). Bulg. J. Agric. Sci., 10: 305-309

The effect of three plant growth regulators on flowering and some quality parameters of mini-carnation (D. caryophyllus f. spray Hort.) cut-flower was studied. Plants of Bulgarian varieties - Yanita, Naslada and Russalka were treated three times with water solutions of Alar (500 and 1000 mg/l), MEIA (500 and 1000 mg/l) and Paclobutrazole (500 mg/l). It was found that:
