Effect and Variation of Different Flooding Degree upon the Tissue Proportion of Pterocarya stenoptera C DC Grown in the Beaches of Changjiang River
Except the proportion of vessel (VP) which varies reversely,the proportion of fiber (FP) ,the proportion of ray (RP) and the proportion of axial parenchyma (APP)vary in the similar pattern in radial The FP and RP vary reversely,while the VP and the APP vary similarly along with the longitudinal The FP and RP of No 1 and No 2 are 65 89%,12 22% and 62 73%,15 07% respectively The differences of the proportion of FP and RP between the two groups are significant,while the differences of the VP and APP aren't significant at 5% level.
