Abstract
This research was conducted to get the basic information for improving production amount as well as fruit quality by using Prohaxadion-Calcium (Pro-Ca) used as 'Sato Nishiki', cherry cultivar, which is most frequently cultivated in Korea. In fruiting trees, we used Pro-ca and concentration of treatment selected 150, 200 and $250\;mg{\cdot}L^{-1}$. When treating Pro-Ca $200\;mg{\cdot}L^{-1}$, we could get the highest effect on inhibition of shoot growth. All treatments of Pro-Ca were increased chlorophyll a and b, respectively compared with control. Although treatments of Pro-Ca treatment showed the decreased effect on leaf area and there was no difference in fruit quality among treatments. Also, Pro-Ca $250\;mg{\cdot}L^{-1}$, sprayed 3 times, and pclobutrazol ($PP_{333}$) 500 and $1,000\;mg{\cdot}L^{-1}$, applicated soil, were treated to 1 year old plnted pot. Pro-Ca and $PP_{333}$ showed inhibition of shoot growth, especially, Pro-Ca showed the more effect than $pp_{333}$ on growth inhibition. Soil applications of $pp_{333}$ showed less effect to enlargement of tree trunk compared to Pro-Ca and control. Pro-Ca and $pp_{333}$ were not difference in number of inter-nodes when comparing to control, but they on decreased leaf area and increased chlorophyll.
