Limit of Last Time to Pluck the Tea Plant in Cold Locality

Abstract

1. These studies were performed to find out the limited time of the last plucking of the tea plant in cold locality. The last plucking was made several times from the beginning of July to the end of August.2. The processes of the growth of new shoots after the last plucking were observed physio-logically and morphologically. It was proved that the later the plucking time, the more inferior the maturity of shoots and the weaker the cold resistance.These tendencies were remarkable in the tea plant plucked after the middle of August.3. The same results were obtained on the growth of the new shoots in the first cropping season of next year.These tendencies were also remarkable in the tea plant plucked after the middle of August of the previous year.4. Therefore, the limited time of the last plucking of the tea plant in cold locality was considered to be the beginning of August.
