RESEARCH ON FACTORS AFFECTING RASPBERRY PLANT GROWTH

The paper presents the results and observations made in Moldova in the period 2002-2010 on the factors that influence plant growth and development phenological phases of 29 introduced raspberry variety. It was established as the beginning of flowering until early fruit maturation medium passes in 27-47 days. After assessing the extent of fruiting plant varieties revealed the Pathfinder, Hybrid Bulgarian, Lloyd George, Rubin Bulgarian, The Latham. The average weight of the raspberry fruits is a criterion for assessing their quality and which highlighted these varieties Hybrid Bulgarian, Rubin, September, Delbard Magnific, Lazarevscaia.

Varieties that showed an increased resistance to drought are Stolicinaia, Malting Promise, Lloyd George.
