The Use of Organic Nano-Supplements of Fertilizer for Lily Forcing Period

Abstract

Lilium is one of the most important ornamental plants after roses, carnations and chrysanthemum in the world that is requested as potted of cut flowers. It is so important to consider its quality along with its production rate in terms of yield (quantity). However, it always needs to intend the product costs aside from quantity and quality. Fertilizer utilization is so important and this may be improved by compounds that promote it and also have synergetic effects themselves. We examined both carboxymethylated chitosan (CMC) and magnetic nano-carbocymethylated chitosan (MNCC) to produce Lilium bulb and advised them especially magnetic chitosan. In this study, these compounds (magnetic and non-magnetic chitosan) at concentrations of zero, 2.5, 5, 10 and 15 mg/l were examined during lily forcing in three cultivars, including Cherbourg, Navona, Brunello, which are from Asiatic and Oriental lilies. The results showed that highest concentrations (10 and 15 mg/l) among between examined concentrations regardless of compounds types and cultivars did not make toxicity and had significant effects on plants biology and physiology [contents of carbohydrates and enzymes affecting these carbohydrates (amylases)]. However, for observing morphological changes may be need to use higher concentrations of these compounds. Note that this needs to examine the non-toxicity of higher concentrations in future studies.
