Abstract:
Taking 63 typical Phallus rubrovolvatus strains as the test materials，the water content of substrate was set as 40%,50%,60% and 70%,the effects of different water content treatments on the growth rate，morphological characteristics and physiological indexes of mycelium were studied,in order to screen out strains with drought resistance.The results showed that the water content of substrate was 40% and 50%，and the germination rate of mycelium was low，and the growth was slow，sparse and weak.When the water content of the substrate was 60%，it was suitable for mycelium growth，with high germination rate，short time and vigorous growth.70% of the water content of the substrate was slightly waterlogged.Although the mycelium germinated early，its growth was uneven and the infection rate of miscellaneous bacteria increased.Physiological and biochemical tests were carried out on two drought-tolerant varieties ZS57 and ZS59.The results showed that ZS57 accumulated more soluble sugar (SS) and then soluble protein (SP) and proline (Pro) to cope with membrane damage and osmotic pressure imbalance caused by drought.Strain ZS59 accumulated SP more quickly to cope with drought.In terms of antioxidant system，both strains mainly increased the activity of superoxide dismutase (SOD)，followed by peroxidase (POD)，catalase (CAT) and reduced glutathione (GSH) to reduce the damage of reactive oxygen species to cells.
