Effect of planting dates and methods and ecofriendly inputs on Germination Characteristics and Seeling Growth of Iranian Ox-Tongue (Echium amoenum) Seeds of Rootstock

In order to evaluation of effect of planting dates and methods and ecofriendly inputs on Germination Characteristics and Seeling Growth of Iranian Ox-Tongue (Echium amoenum), a split split plot experiment based on CRD design with three replications was conducted in ۲۰۱۴ 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 ۲ planting dates (۱۰ February and ۳ April ۲۰۱۲), ۲ planting methods (seed planting and transplanting) and ۳ 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 ۱۸ and ۱۷% and improved germination rate ۳۲ and ۳۳% 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 ۴۴% compared to control. Effect of planting date was significant on radicle and plumule dry weight.
