振动对三角梅苞片脱落和乙烯合成的影响
Effects of Vibration on Shedding and Ethylene Synthesis in Bougainvillea glabra Bracts
摘要
Abstract
In order to investigate the effects of vibration on shedding and ethylene biosynthesis of potted Bougainvillea glabra,the shedding rate of bracts of potted Bougainvillea×buttiana'Miss Manila'under vibration,closed environment and vibration+closed environment,and the related indexes of ethylene synthesis were measured for 4-24 h after treatment.The results showed that the shedding rate of bracts was significantly higher than that of the control within 7 days after vibration+closed environment and vibration treatments,and the ethylene release,1-amino-cyclopropane-1-carboxylic acid(ACC)content,ACC synthase(ACS)and ACC oxidase(ACO)activities in bracts of bracteoles 0.5-1.4 cm long(S1)and 1.5-2.4 cm long(S2)were significantly higher than those of the control,which overall trends were first increased and then decreased.The relative expression of BsSAMS,BsACS,BsACO genes in S1 and S2 increased significantly,and which change trends were consistent with those of ACS and ACO activities.Therefore,shedding rate of bracts,ethylene content,key enzyme activities of ethylene biosynthesis,the expression of ethylene synthesis genes BsSAMS,BsACS,BsACO of potted'Miss Manila'all increased significantly after vibration,and the closed environment could promote the effect of vibration.关键词
