海南广藿香叶肉细胞超微结构对盐胁迫的响应
Respond of Salt Stress on Ultrastructure of Mesophyll Cells in Pogostemon cablin
摘要
Abstract
The ultrastructure changes of P.cablin stressed with different concentrations of salinity were stud-ied using tranmission electron microscope .The results indicated ,the regular and compact chloroplast had integrat-ed membrane system under the water free of salinity .The chloroplast abundant with big starch grain was closed in a mass of mitochondria under low concentration of salinity ( 40 mmol/L NaCl ) .The membrane system of chloro-plast departing from cell wall and less of starch grain was degenerated and destroyed ,the thylakoids of dissocia-tive chloroplast was intumescent ,degenerated and loosened obviously ,and the half-vacuolated mitochondria were observed under higher concentration of salinity .This suggested that salt stress had inhibitory effects on the growth of P.cablin seedling.The higher the salt concentration was ,more obvious the inhibition effect was .It would pro-vide the cytological basis for salt-tolerant variety breeding and patchouli planting in saline -alkali land .关键词
