Evaluation of Germination Characteristics and Seeling Growth of Iranian Ox-Tongue (Echium amoenum Fisch & Mey.) Seed Resulting from the Rootstock treatmented by Biological and Chemical Fertilizers in Different Planting Dates and Methods
In order to evaluation of germinaton characteristics and seedling growth of Iranian Ox-Tongue (Echium amoenum) seeds resulting from the rootstock in conditions of application of biological and chemical fertilizers in different planting dates and methods, a split split plot experiment based on CRD design with three replications was conducted in 2014 year, in Ferdowsi University of Mashhad, Iran. The experimental treatments included seeds resulting from treated Iraninan Ox-Tongue with different agronomic factors in farm such as 2 planting dates (10 February and 3 April 2012), 2 planting methods (seed planting and transplanting) and 3 different types of biological and chemical fertilizers (mycorrhiza (Glomus moseae), biosulfur (included Thiobacillus spp.), chemical fertilizer and control). The results showed that mycorrhiza and biosulfur increased germination percentage 18 and 17% and improved germination rate 32 and 33% compared to control, respectively. Mean germination time in conditions of seed planting was less than transplanting conditions. Mycorrhiza application in conditions of seed planting increased radicle length to plumule length 44% compared to control. Effect of planting date was significant on radicle and plumule dry weight, so that the highest radicle (0.0016 g) and plumule (0.0075 g) weight obtained in planting date of 10 February 2012.
