Abstract
The current research was conducted at the Experimental Station and in the Laboratory of Vegetable and Floriculture Department, Faculty of Agriculture, Mansoura University during the two successive seasons of 2006/2007 and 2007/2008. This investigation included two parts of experimental work. The first experiment was to study the effect of sowing date on some growth parameters of snapdragon and statice plants. The second one aimed to study the effect of different preservative solutions on some post harvest characters and chemical constituents of cut flowers of the aforementioned plants.
MATERIALS AND METHODS
First experiment: Effect of sowing date on some growth characters of Antirrhinum majus L. cv. Riesen Vorbote and Limonium sinuatum, L. cv. Pacific plants
The seeds of both plant species were sown at three different dates in both seasons to determine plants height, number of spikes on snapdragons and number of panicles on statice per plant, number of flowers on spike of snapdragons and number of branches on panicle of statice, fresh weight.
Second experiment: Effect of some preservative solutions on some post harvest characters and chemical constituents of Antirrhinum majus, L. cv. Riesen Vorbote and Limonium sinuatum, L. cv. Pacific cut flowers
Fresh weight of snapdragon flower spikes and statice panicles were recorded before treatment and placed in prepared preservative solutions in glass containers under laboratory conditions. Each spike or panicle was placed in 100 ml glass cylinder filled with the designated preservative solution.
RESULTS
- The first date of sowing (September, 1st) induced the highest values of plant height (cm), number of florets/spike or panicle and fresh weight (g/spike) in both seasons.
- Holding snapdragon cut spikes in a solution containing 8-HQS at 200 ppm plus sucrose at 20 g/l recorded the highest increase in longevity period, fresh weight, absorbed solution and improved water balance.
- Spraying statice cut flowers with 100 ppm BA and holding it in a preservative solution containing 8-HQS at 200 ppm gave high keeping quality and longest vase life.
RECOMMENDATIONS
It could be recommended to sow the seeds of Antirrhinum majus L. cv. Riesen Vorbote and Limonium sinuatum L. cv. Pacific early during September under the conditions of Dakahlia Governorate to obtain better vegetative growth and flowering characters.
It could be also recommended to use preservative solutions containing 8-HQS at 200 ppm plus 20 g/l sucrose to extend vase life, increase fresh weight and water uptake and improve water balance of Antirrhinum majus cut spikes. High keeping quality and longest vase life can be obtained when Limonium sinuatum cut flowers are sprayed with 100 ppm BA and held in a preservative solution containing 8-HQS at 200 ppm.
