| Abstract: | There were significant differeces in the big and small fibrovascular bundles among different species in rice.Most of the fibrovascular bundles were sampled in the middle level.It showed nomal distribution in different tillers.The middle level of the tillers as samples were used to study the characteristics of the fibrovascular bundles.It manifested subspecies character in the ratios of big to small fibrovascular bundles numbers in necks and the second internode to big fibrovascular bundle.Characteristics of middle level tillers showed typical in sampling. |
