温度周年变化与桑树植原体消长的关系

Abstract

Abstract:

By polymerase chain reaction (PCR), the seasonal variation of the phytoplasmal amounts in mulberry tree was determined.It was demonstrated that the phytoplasma was unevenly distributed in the host.In stem, its amount increased during the growing season, which reached its peak in July and was undetected in winter; in leaves, the situation was similar to that in stem but the peak was in August.In roots, its amount was lower and hardly varied in all the year round.It was indicated that the seasonal variation of phytoplasma in mulberry trees was related to that of temperature.

Key words: Mulberry tree phytoplasma, Polymerase chain reaction(PCR), Temperature
