Lilium is scientifically named Lilium longiflorum is a cut bulbous flower. In the process of producing lilium flowers, the quality of the flowers has a special importance and one of the most important factors is proper nutrition. Balanced and optimal nutrition is easily possible in hydroponic systems. In contrast, improper management of the nutrient solution significantly reduces plant growth and impairs the quantitative and qualitative production of the product. Nutrients often interact and the diagnosis of deficiency or toxicity of the nutrients is made by experimental studies under controlled conditions. In order to study the effect of different concentrations of potassium on lily growth and postharvest life, a hydroponic experiment based on a randomized complete design with different concentrations of potassium at three levels of 0, 3 and 6 mM in three replicates in planting bed of 40% perlite + 60% sand was performed. The results showed that most of the plant growth indices, especially shoot dry weight, decreased with potassium consumption in nutrient solution, but at a concentration of 6 mM potassium in nutrient solution, postharvest life increased significantly compared to the control. پرونده مقاله

An in vitro propagation method of English yew (Taxus baccata L.) through organogenesis method using kinetin (Kin) and indole 3-butyric acid (IBA) as plant growth regulators and apical bud as explant is presented. Apical buds excised from mother plants were inoculated on Murashige and Skoog (MS) medium supplemented with different concentrations and combinations of Kin (0.00, 0.50, 1.00 and 2.00 mg l–1) as a cytokinin and IBA (0.00, 0.50, 1.00 and 2.00 mg l–1) as an auxin. Results showed that the highest number of node (6.75) was obtained on MS medium containing 2.00 mg l–1 Kin. The maximum shoot number (5.00) was obtained on MS medium supplemented with 1.00 mg l–1 Kin together with 1.00 mg l–1 IBA. The largest number of root (6.50) was produced on explants grown on medium enriched with 2.00 mg l–1 Kin together with 1.00 mg l–1 IBA. Plantlets were transferred to pots filled with perlite and peat moss in equal proportions for acclimatization. These plantlets were acclimated and successfully established in cultivation beds. . پرونده مقاله
