Study on the influence of B on cell wall components in different B efficiency rape cultivars

A research was made to study the influence of boron on the cell wall components in rape cultivars (Brassica napus) with different B efficiencies by the technique of nutrient solution cultivation. The results showed that the extraction ratio of cell wall and the cellulose content in the cell wall in root were higher than that in leaf, but pectin content was lower, and there was no significant difference to the semi-cellulose. B deficiency made the cell wall extraction ratio higher, but made no significant influence to the cell wall component in root and leaf. There was no significant difference to the cell wall components in root and lower leaf in different B efficient rape cultivars. In the upper leaf the chelate-soluble pectin content in B efficient rape cultivars was significantly higher than that in B inefficient rape cultivars, but the alkaline-soluble pectin was significantly lower than that in B inefficient rape cultivars, and there was no significant difference to cellulose, semi-cellulose and pectin contents.
