Abstract:
The oriental lily ‘Siberia’ was used as the experimental material,and four different strains of ACC-deaminase containing plant growth promoting rhizobacteria (PGPR),including sphingobacterium （SN-2）,acine to bacter bacteria （BG）,acinetobacter bacteria （XG）,chryseobacterium （F） and a mixture of the above-mentioned strains were fertilized separately in its cultivation while using water as control （CK）.Some indices of lily,including plant height,relative chlorophyll content,stem diameter,flowering period and number of flower buds etc.,were investigated in order to explore the effects of different ACC-deaminase containing PGPR strains on its growth and physiological property,it provides theoretical support for the rational application and development of strains fertilizer.The results showed that BG strain was the best among them in the plant height,which was 1027% higher than CK.F strain had the best effect on prolonging the flowering period of whole plant,which was 570% higher than CK.SN-2 strain had the best effect on prolonging the flowering period of single flower,which was 1470% higher than CK.XG strain had the best effect on reducing the amount of ethylene biosynthesis,which was 2963% lower than CK.The mixed bacterial liquid of four strains had some promoting effects on the quality of harvesting bulblets,including the fresh weight,circumference and root length,which were respectively 5444%,2509% and 4879% higher than CK.Based on the comprehensive and comparative,analysis,BG strain performed the best among all tested strains in the growth of orientallily ‘Siberia’.
