Proceedings of Plant Growth Regulators Society of America. December. p.93. Interpretive Summary: Technical Abstract: Fruit-tree nurseries in the USA produce many millions of trees each year. Interestingly, few uses for bioregulators have been developed for the nursery fruit-tree industry. The principal objective for which bioregulators might be useful is the induction of branching under nursery conditions. On the West Coast, a few nurseries in Washington now use proprietary mixtures of 6-benzyladenine and gibberellins A4 and A7 to stimulate feathering (lateral branching) on apple trees destined for high-density plantings as well as for back-yard plantings. One nursery in California reports the use of a foliar nutrient product for stimulation of branch development in apple trees. Because of the absence of bioregulator products that can induce lateral branching in many fruit-tree species, bioregulator use has not become a common component in fruit-tree production. Recent research underway in Washington has suggested that a new bioregulator product, cyclanilide®, may have considerable promise for induction of lateral branch development in fruit trees under nursery conditions. |
