Effect of silicium salts spray on morphological traits in Rosa hybrids cv. grand prix

For study the effect of silisum spray in rosa flowers, experiment in a completely randomized design with 7 treatments included 3 replications and each replications with 3 pots were conducted. Treatments include sodium silicate, calcium silicate and potassium silicate, each with two levels of 25 and 50 ppm and the pot was considered as control without spraying. Pots, two times in the first week of spraying was conducted on the same basis. Morphological traits such as flower fresh weight, flower dry weight, flower diameter, stem diameter and flowers stem lenght were evaluated. The results showed that the treatment of CaSi 50 ppm had the greatest effect on correction the traits. Result at 1% statistical level had significant effect.
