Abstract

The analysis of principal components and canonical correlation was applied to study the correlation among quality indicators of bamboo shoots of Dendrocalamopsis oldhami and soil nutrients in 12 production areas in both Fujian Province and Zhejiang Province. The results showed that the cumulative variance rate of the first three principal components was 84.658 per cent in the principal component analysis. Therefore，the three principal components could be used as composite indicators which reflected the main quality characters of bamboo shoots. The first three principal components included the contents of reducing sugar and water-soluble total sugar，the second was water，and the third were protein and total ash. The quality characters of bamboo shoots were significantly correlated with soil nutrients，the first canonical correlation coefficient was 0.999 99 with the canonical information accounted for nearly 100 per cent of the total canonical information. The soil affected the quality characters of shoot mainly through its pH value，total nitrogen，and organic matter. The contents of reducing sugar，water-soluble total sugar and water in the shoots were predicated by the first canonical variables.［Ch，3 tab. 15 ref.］
