主　　题：Bamboo fiber parenchyma cell microfibril aggregate size arrangement 

摘      要：Understanding the assembly and spatial arrangement of bamboo cell wall components is crucial for its optimal *** cell walls consist of aggregates of cellulose microfibrils and *** the present study,the size and arrangement of cellulose microfibril aggregates in the cell walls of sclerenchyma fibers and parenchyma cells in moso bamboo were investigated with NMR and *** NMR measurement showed that the characteristic sizes of the microfibril aggregates of fibers and parenchyma cells were approximately 25.8 nm and 18.8 nm,***,high-resolution SEM showed the size of microfibril aggregates varied little across the cell wall of sclerenchyma ***,there were significant size differences between the broad and narrow lamellae both in fiber and parenchyma cells,which is thought to be closely related to the orientation of microfibrils in these *** microfibril aggregates in the fibers mainly appear in a random arrangement,although occasionally in a radial or tangential arrangement in individual *** cells have a relatively thinner cell wall layers,in which microfibril aggregates appear in a concentric lamellar arrangement.
