BIOPHYSIOLOGICAL INTERDIPENDENCE BETWEEN MALE AND FEMALE INFLORESCENCES IN HAZELNUT

M.L. Miaja, G. Me, P. Romisondo
The influence of male inflorescences on fruit set was investigated in Cravanzana (CN) on the cultivar Tonda Gentile delle Langhe (TGL). Branches that developed both male and female inflorescences were divided into 5 categories of length in relation to their vigour. From 2/3 of these branches in the first decade of September, male inflorescences were completely (100%) or partially (50%) removed; the others were used as test.

The fruit set was not significatively influenced by catkins.

Moreover the time and length of microsporogenesis of cv TGL in Cravanzana were determined: the mother cells were evident in the first decade of August and pollen appeared before 20th September.

The carpological characters of the nuts from investigated branches were also examined; the percent kernel varied in relation to the length of branches but not to the presence of catkins.
