Use of forcing solution techniques to study the correlation of plant growth regulators with bud dormancy, subsequent rooting, in vitro responses and protein expression of forced softwood growth of woody plant species

Chestnut, lilac, privet, spirea, white weeping oak and 5-leaf aralia were tested. Optimum bud break was obtained by soaking the basal 1/3 of dormant stems either in 10% bleach solution or in 75% ethanol solution for 15 minutes. Bleach or ethanol soaks exerted negative effects on bud break for spirea, but hastened bud break for lilac and privet. GA;IAA and NAA included in forcing solution enhanced subsequent rooting of forced softwood cuttings for privet. GA;GA...
