Abstract:
3-year-old ‘Cabernet Franc’ was used as materials,and principal component analysis was used to study the efffects of thinning leaf and berry manipulation treatment after anthesis on sugar and phenols content in berry,in order to explore the suitable rate of foliar areas to berry number on ‘Cabernet Franc’,in eastern foot of Helan Mountain.The results showed that the rate of foliar areas to berry number which was increased after anthesis could increase the content of total soluble soluble sugar,anthocyanin,tannin and total phenol,and the titrate acid content was decreased,berry quality at harvest time were increased.The total sugar content during experiment period was significant positive correlated with anthocyanin content,and significantly negative correlated with tannin,total phenol and titrate acid contents.The contents of total soluble sugar,anthocyanin,tannin and total phenols in the berry of 20 cm2 per berry were 16.9%,19.1%,15.7% and 15.9% higher than those in CK（15 cm2 per berry）,respectively,and the differences all reached significant levels.Berry quality of different treatment were determined by using principal component analysis,the berry quality comprehensive socre of 20 cm2 per berry was highest than other treatment.So,20 cm2 per berry was the most suitable leaf-berry ratio,and this rate of foliar areas to berry number could significantly improve the ‘Cabernet Franc’ berry quality in eastern foot of Helan Mountain.
