Abstract:

In order to solve the practice production of female and male flowers of improper proportion of hazelnut. As the hybrid hazel 84-254 (‘David’) grown in Changping of Beijing for the object of study, analysis of GA and MET two plant growth regulators on the impact of male and female flowers of hybrid hazel. According to the results of field trials in 2009-2010, use of SPSS 18.0 analysis of variance of data, we thought that: (1) GA had no significant effect on the number of female flower buds, significantly reducing the number of male inflorescence, increased the proportion of male to female; MET significantly reduced the number of female flower buds, had no significant effect on reducing the number of male inflorescence, reducing the proportion of male to female. (2)The distribution of male and female on the tree of hybrid hazel 84-254 (David), the number of female flower buds lower>middle>upper; the number of male inflorescence lower>upper>middle. The number of female flower buds and male inflorescence was not significant difference on various parts of the tree. As the trees GA and MET treated, the distribution of the number of female flower buds and male inflorescence on different part of it was not significant. For the annual twig on hybrid hazel 84-254 (‘David’), GA significantly inhibited the number of male inflorescence, increased the proportion of male to female. MET significantly reduced the number of female flower buds and reduce the proportion of male to female. The number of female flower buds and male inflorescence on ‘David’ was not significant difference on various parts of the tree.
