Cuttage Technology And Ecological Adaptability Research Of The Five Kinds Of Vibumum L.

This paper choosing five kinds of flowers and trees from the Viburnum plants V.macrocephalum f.keteleeri、V.plicatum f.tomentosum、V.propinquum、V.opulus var.calvescens、V.tinus. as research object, V.odoratissimum as a reference group at the same time, cuttage breeding characteristics and ecological adaptability of thegenus Viburnum tests were conducted to provide a set of reference data for its resource devel-opment and application in Changsha.The main contributions of this paper are list as follows:V.tinus.4 hours NAA100mg/L treatment in river sand, has the highest rooting rate equally, reached 84.33%; In 4 hours IAA100mg/L treatment in coir, it has the maximum lateral roots,21 in the center of five Viburnum plants; And in 12 hours NAA100mg/L treatment in peat soil+perlite (2:1), has the longest adventitious roots, 48.33mm longest of five Viburnum plants. V.plicatum f.tomentosum,12 hours IAA50+NAA50mg/L treatment in coir, has the highest rooting rate equally, reached 83.33%. It’s the highest rooting rates in all experiment with same factors. In 12 hours IAA100mg/L treatment in peat soil+perlite, it has the maximum lateral roots, reached 24, which is the most of five Viburnum plants; In the IAA50mg/L treatment in peat soil+perlite, has the longest adventitious roots, reached 41.67mm. V.macrocephalum f.keteleeri cutting shoot,12 hours treatment in both IAA50+NAA50mg/L and IAA50mg/L in coir, has the highest rooting rate equally, reached 53.33%. In 12 hours IAA50+NAA50mg/L treatment in coir, it has the maximum lateral roots, reached 15.33 , and in the IAA50+NAA50mg/L treatment in river sand, has the longest adventitious roots, reached 19.17mm. V.propinquum cutting shoot,4 hours treatment in both IAA50+NAA50mg/L and NAA50mg/L in coir, has the highest rooting rate equally, reached 51.33%, and in the IAA50+NAA50mg/L treatment in coir, has the maximum lateral roots, reached 19. The average length of adventitious roots of V.propinquum cutting shoot is low in the experiment, in the 12 hours NAA50mg/L treatment in peat soil+perlite, has the longest adventitious roots, reached 13.67mm. V.opulus var. calvescens,12 hours treatment in both NAA100mg/L and IAA50+NAA50mg/L in peat soil+perlite, has the highest rooting rate equally, reached 86.67%; and in the 12 hours IAA100mg/L treatment in coir, has the maximum lateral roots, reached 22.67; In the 12 hours 1AA50mg/L treatment in peat soil+perlite, has the longest adventitious roots, reached 41.67mm.Five the survival rate of Viburnum L:V.tinus> V.opulus vai.calvescens> V.plicatum f.tomentosum> V.macrocephalum tketeleeri> V.propinquum. The number of lateral roots:V.plicatum ttomentosum> V.opulus vax.calvescens> V.tinus> V.macrocephalum f.keteleeri> V.propinquum. Average length of adventitious root: V.plicatum ttomentosum> V.opulus vax.calvescens> V.tinus> V.macrocephalum tketeleeri> V.propinquum.The survival of cuttings of five Viburnum seedling transplanting basin after two weeks. Proline content:V.opulus var.calvescens> V.macrocephalum tketeleeri> V.propinquum> V.tinus> V.plicatum ttomentosum. Soluble protein content is basically close to, MDA content:V.tinus> V.opulus vai.calvescens> V.propinquum> V.macrocephalum tketeleeri> V.plicatum ttomentosum. Peroxidase content: V.propinquum> V.macrocephalum tketeleeri> V.opulus var.calvescens> V.tinus> V.plicatum ttomentosum. Catalase content:V.propinquum> V.tinus> V.macrocephalum tketeleeri> V.plicatum ttomentosum> V.opulus vax.calvescens. Total antioxidant capacity:V.macrocephalum tketeleeri> V.opulus vai.calvescens> V.propinquum> V.plicatum ttomentosum> V.tinus.
