Effect of some treatments on vas life of Rosa cv. Queen Elizabeth flowers

الملخص EN

Five years old Rosa cv.

Queen Elizabeth flowers were taken from shrubs grown in Agricultural College gardens at the University of Dohuk.

The length of cut flowers petule was estimated at 50-70 cm.

The effect of flowers cutting stage was studied on vase flowers age stage of non opening sepals, stage of semi opened sepals, stage of non opening petals, stage of semi opened petals and the stage of full petals opening interacted with three different methods of cut flowers, cutting the flowers and putting them in water after 10 minutes, cutting the flowers and putting them directly in water and cutting the flowers under water directly.

The experiment was arranged according to factorial randomized complete design in four replicates and 15 flowers for each replicate.

The highest percentages mean of petals falling down at petals full opening and at semi opened petals were recorded (97.35%).

Flowers’ cutting at the stage of non opening petals was better and the mean percentage of petals fulling down was 55.55%.

Whereas, the flowers were declined and the mean of petals falling down percentage was 90.83%, when they were cut and put in water after 10 minutes.

While the percentage of petals falling down was better when the flowers were cut under water directly (72.57%).

Cutting flowers at full opening stage for cutting the flowers and putting them in water after 10 minutes and cutting the flowers and putting them directly in water gave 100.00% petals falling down as compared with those cut under water (92.06%) for the same treatment.

The lowest petals falling down percent was 43.74% which was recorded while cutting flowers at the stage of non opening sepals and those cut under water directly .
