UTICAJ NOVIH VEGETATIVNIH PODLOGA NA BUJNOST, PRINOS I POMOLOŠKE OSOBINE SORTI ŠLJIVE „ČAČANSKA LEPOTICA“ I „JOJO“

Despite numerous deficiencies, the Myrobalan seedling is the most common plum rootstock in the Republic of Serbia. Although a large number of vegetative rootstocks exists worldvide, they are generally not available to producers in our country. In this work, we investigae the influence of four vegetative rootstocks: ʻWavitʼ, ʻWeivaʼ, ʻDoceraʼ and ʻDospinaʼ (last two are hypersensitive to Sharka virus) on tree vigour, yield and pomological properties of two plum cultivars ʻJojoʼ and ʻC ačanska Lepoticaʼ. All rootstocks differently affected examined properties. The largest tree vigour in both cultivars was caused by ‘Weiva’, while the smallest tree vigour of ‘Čačanska Lepotica’ was affected by ‘Docera’ and ‘Wavit’, as well as by ‘Dospina’ in ‘Jojo’. The highest yield was induced by ‘Weiva’, and smallest by ‘Docera’ and ‘Wavit’. Rootstocks ‘Weiva’ and ‘Wavit’ showed the largest influence on fruit weight while ‘Dospina’ and ‘Wavit’ affected morphometric properties the most. In terms of cultivars, ‘Jojo’ had largest tree vigour, yield, fruit weight and morphometric properties compared to ‘Čačanska Lepotica’.
