Effect of coated covers with copper sulfate filtered for infrared radiation in vegetative and flowering traits for the two cultivars of snapdragon (Antirrhinum majus) plant

The study was conducted on the two cultivars of snapdragon (Antirrhinum majus) plant are whiteSnapdragon and yellow Snapdragon, to compare the covers with concentrations (0, 4, 8%) of coppersulfate. A factorial experiment was conducted according to Complete Randomized Blocks Design, withthree replicates and nine plants for each replicate. The results showed significant differences invegetative and flowering traits for the growing plants under the filtered covers with two copper sulfateconcentrations compared to the control plants. where the results of vegetative growth showed asignificant decrease in plant length and significant increase in the number of branches, number of leaves,leaf area, the percentage of chlorophyll and the leaves content of carbohydrate, While the results offlowering growth showed a delay in the time of the flowering of the first floret and a decrease in thelength of the main inflorescence for the growing plants under the coated covers with both copper sulfateconcentrations compared to the control plants.
