The influence of climate on branches at Bulgarian mulberry varieties (Morus spp. L.)
Zdravko Petkov
Abstract: The influence of climate conditions on branches from twelve Bulgarian mulberry varieties has been investigated during 2010 - 2012 at SCS – Vratsa. Significant variation of tested characters both under the influence of climatic conditions and within the different varieties as well was found. The calculated correlations between mulberry branch’s characters and the climatic parameters have been ranged from negative to positive and from very weak to moderate. For the town of Vratsa’s conditions the yield of leaves per 1 branch correlates negatively with rainfall for the period from September to May and with rainfall for mulberry vegetation period and positively with sum of active temperatures for this period.
