For reducing the cultivating periods, realizing seedling production of large quantity and exploring rooting mechanism about Picea crassifolia,the cutting propagation technique ,rooting mechanism and anatomy of Picea crassifolia have been studied. ⑴The study of cutting propagation technique shows:①in the aspect of hormone,IBA is the best to stimulate rooting,NAA and IAA are at middle,ABT1 and CK(water) are worst.②for IBA concentration,100ppm is the best,50 and 150ppm at the middle, 0 and 200ppm are the worst...
