摘　　要：Pollen wall is the most complicated cell wall in plant. It is composed of outer exine and inner intine with the exine fiar- ther divided into sexine and nexine. The composition of in- tine layer is generally considered to be same as a plant cell wall which is mainly composed of cellulose. Nexine layer can only be observed under transmission electron microscope. Recent investigation suggested that the major composition of nexine is arabinogalactan proteins （Jia et al., 2015）.Pollen wall is the most complicated cell wall in plant.It is composed of outer exine and inner intine with the exine further divided into sexine and nexine.The composition of intine layer is generally considered to be same as a plant cell wall which is mainly composed of cellulose.Nexine layer can only be observed under transmission electron microscope.Recent investigation suggested that the major composition of nexine is arabinogalactan proteins(Jia et al.,2015).The sexine layer is composed of sporopollenin which is quite
