摘要

Getting difficult to root plant species to propagate has been a challenge for the plant nursery industry. Efforts to achieve successful propagation have turned to incorporating growth stimulators in a planned sequence to optimize growing activity at specific development stages. The goal of this study was to test a sequence model that expedites the propagation of woody plants through modification of a plant growth regulator (PGR) addition sequence in the basic forcing solution. GA_3 and IBA were introduced sequentially in the basic forcing solution to expedite propagation. This model forcing solution system was established by sequentially including one of the two PGRs in the forcing solution using the following sequence: (1) GA_3 was initially included in the basic solution for 1 day to enhance bud break and shoot elongation and then (2) on day 2 the GA_3 was replaced by IBA and transferred to fresh aliquots of basic forcing solution to "prime" the softwood cuttings for rooting. IBA was introduced to counteract the undesirable effects of GA_3 on rooting following its favorable effects on bud break and shoot elongation, and stimulated rooting. This forcing solution system expedited the propagation process of the test species and could be readily used for difflcult-to-root species. We recommend it to commercial propagators for propagating softwood cuttings from dormant stems in the offseason as way of minimizing the use of valuable greenhouse space for stock plants.
