Evalution Kelussia odoratissma seed dormancy breaking under gibberellin acid and stratification

Abstract

In order to survey the effects of dormancy-breaking methods on Kelussia odoratissmaseeds a completely randomized design was implemented at five replications in Research Institute of Forest and Rangelands, 2010. Treatments were: seed stratification (4°C for 4, 6, 8 and 10 weeks), socking in gibberllic acid (250, 500 and 1000 ppm solutionfor 12 hr) and seed stratification and gibberllic  acid combination (500 ppm +4°C for 4,6,8 and 10 weeks). Results showed significant differences among treatments (pKelussia odoratissma α-amylase activity obtained of   500 ppm +4°C for 8 and 10weeks (14.2 and 13.8 nm seed-1 min-2). Results indicated Kelussia odoratissma seed treatment with 500 ppm +4°C for 8 and 10weeks was the best treatment for induction Kelussia odoratissma seed germination
