Evaluation the effect of spray phenyl alanine and selenium in pre-harvest on Flowering and Stem Strength Alstroemeria(Alestromeria spp.)

To study the Evaluation the effect of spray phenyl alanine and selenium in pre-harvest on Flowering and Stem Strength Alstroemeria(Alestromeria spp.), factorial experiment in a completely randomized design with 7 treatments, 3 replication and each treatment with 3 pots, a total 63 pots were conducted. Treatments includ Phenyl alanine with 3 level, 25, 50 and 100 ppm, selenium with 3 level, 2.5, 5 and 10 ppm and No spraying pot were used as controls. Spraying pots was done three times a week at the same base, so that the last Spraying about a week befor proper stage of harvesting the flowers for delivery to the market(a slight discovery of flower buds and vivid colors). Physicochemical and enzymatic traits of the plant traits such as fresh weight of flower, dry weight of flower, cell membrane stability index, number of flower, plant length, anthocyanine of petals, total chlorophyll of leaves, protein, superoxide dismutase, peroxidase and phenylalanine ammonia-lyase enzymes activity and flower life on plant were evaluated. The results showed that Selenium 2.5ppm treatment had the most effect on the improvement of traits such as flower fresh weight, flower dry weight, cell membrane stability index. Phenylalanine 100ppm treatment also had the most effect on the improvement of traits such as number of flower, plant length, protein, phenylalanine ammonia-lyase enzymes activity and flower life on plant and Phenylalanine 50ppm treatment had the most effect on the improvement of anthocyanine of petals, total chlorophyll of leaves. The highest activity of superoxide dismutase and peroxidase enzymes was obtained in selenium 10ppm treatment. The correlation between traits showed cell membrane stability index, anthocyanine of petals and total chlorophyll of leaves with number of flower and plant length and also protein, superoxide dismutase, peroxidase and phenylalanine ammonialyase enzymes activity with anthocyanine of petals and total chlorophyll of leaves, positive and significant at 5% level and other traits, positive and significant at 1% level.
