| Abstract:
Typically, rose growers have perceived that there may be great benefits to completely removing old conventional plantings and use the greenhouse space to convert production to soil-less culture in containers and a training system using bending. But this conversion is expensive and has some environmental drawbacks. This experiment determined that 8-year-old commercial greenhouse rose plants, cultivated in soil and conventionally trained, could be converted successfully to bending. The experiment determined that bending alone had a positive effect on production and quality for most cultivars. In 5 rose cultivars, established production plants were hedged and experimental plots were trained with either bending or conventional training. Production and quality were monitored for one year in each training system. With bending, production increased in four cultivars 2-22 % and decreased 13% in one cultivar. With bending, fresh weight increased 2.8-10.2 % in four cultivars and decreased 8.8% in one cultivar. With bending, stem length increased slightly in three cultivars 1.3-3.9 % and in two cultivars decreased slightly in 0.7-0.8%. | |
