Abstract
To understand the harm status of dwarf mistletoe to natural and secondary spruce forests in Qinghai,the growth and physiological indices of spruce branches and leaves suffering varying degrees of damage were measured. The results showed that when spruce subjected to dwarf mistletoe infestation,its growth and physiological indicators changed drastically,and with increasing of harm degree,the competition for water and photosynthetic products between dwarf mistletoe and spruce branch increased,which result in spruce nutritional imbalance,weak growth and death.
