Study of Snow Flake Cultivation and Customizability in Guilan

The Snow flake with the scientific name Leucojum is a bulbous plant and belongs to Amaryllidaceae family. There are only two species currently classified in the genus Leucojum: Spring snow flake (Leucojum vernum) and Summer snow flake (Leucojum aestivum ). The genous that is growing in Iran is Summer snow flake (Leucojum aestivum). In Iran it has been seen in Guilan, Mazandaran and Azarbaijan. In Guilan it naturally grows in Astane and Lahijan. This plant has ornamental uses in Europe and America, hence this research aims are localizing this plant and investigating the proposed beds for using in pots and landscape. This experiment was done in split-plot and calculated in a randomized complete block design. The onions were collected in the winter of 2010, from the Niyakoo village of Astane, 5 Km before Lahijan and transferred to the experiment place, the farm of department agriculture of Islamic Azad University of Rasht. The planting media tested include: 1.The main habitat soil of plant 2. the composition of mould leaf + rice husk, 3. Loamy soil + thoroughly rotten manure + rice husk, 4. Loamy soil + thoroughly rotten manure + rice husk + mould leaf. The onions were selected in single and multiple (as in their original habitat) and were placed in two light postions: 1. The low light, under the jute (the same lighting condition as its main habitat), 2. The outdoor light. The result of variance analysis showed that the light conditions were significant in the levels of 5 and 1 percent for the different characteristics including leaf length, flowering stem length and the number of flowering stem. In addition, the result showed that the interaction of ligh conditions and media on the vegetative growth and flower stem were significant in the levels of 5 and 1 percent. The comparison of averages proved that low light conditions, was more effective for the vegetative growth than the outdoors light. This is done while the environmental light had better results in the reproductive phase. According to the obtained results, it can be announced that all proposed media were effective for the snow flake growth, but the treatment of mould leaf with rice husk was the best one, especially for the multiple bulbs. Ultimately, the snow flake can be introduced as a localizable plant, that can be planted in single and multiple onions, in different light conditions, in landscapes.
