Title

The effect of various levels of indole butyric acid and substrate on the rooting of Maymars cuttings in 4 seasons-Juniperus Sabina

Pages

Abstract

 Background and objectives: Native juniper of Maymars is one of the valuable species in Mountainous forests of Golestan province and is one of the main pillars of natural ecosystems of Iran’ s mountainous forests. At the moment, most of these trees have the hardest biological conditions and they try to be survived. So it is needed to practice finding the protection and propagation ways to keep these plants. Material and methods: To recognize the best Season and substrate, and also proper Treatment to root the cuttings of Maymars, recent experiment was done with 5 levels of indole butyric acid (0, 1000 ppm, 2000 ppm, 4000 ppm & 8000 ppm) in 4 substrates contained perlite, perlite-cocopite (1: 1), Pumice and rooting substrate (combination of sand, perlite, cocopeat, vermicompost and peat moss) and 4 Seasons of the year on Maymars cuttings with length 15 cm. The experiment was done in 3 replications, and each one contained 9 cuttings. The aim of the experiment was finding the best Season; substrate and natural Treatment to asexual propagate of this plant (cutting). At the end of each Season, rooting percentage, root length, root numbers, fresh and dry weights of roots in each substrate and Treatment were registered. Results: The result showed that the best Season for rooting the Maymars cuttings is spring and the best substrate is perlit cocopeat (1: 1). The best rooting between all Treatments was related to level 4000 and 1000 ppm of indole butyric acid in spring with more than 50% rooting. Lowest amount of rooting was related to all Treatments of winter with fewer than 2%. Highest number of roots was seen in spring and level of 2000 ppm of indole butyric acid and also in perlit-cocopeat substrates (1: 1) and the fewest one was seen in pumice substrate. Maximum root length was seen in spring and it should be mentioned that between all substrates, the best ones were perlit – cocopeat, perlite and rooting substrate without any significant difference. Highest amount of root fresh and dry weight was resulted in spring. And also highest amount of root fresh weight was found in rooting substrate. On the other hand, the highest amount of root dry weight was seen in pumice substrates as well. Conclusion: So it can be concluded that to propagate Maymars cutting, spring is the best Season with the best result of rooting. Also indole butirice acid is effective Plant Growth Regulator to propagate Maymars juniper. The best rooting between all Treatments was related to level 4000 and 1000 ppm of indole butyric acid in substrate of perlit cocopeat (1: 1) in spring with more than 50% rooting.
