The evaluation of fruits production and physico-chemical features for some cherry cultivars created at S.C.D.P. Iasi

Abstract

This paper presents some aspects concerning the influence of the environment factors between 2011-2013, registered in the Iasi area, on the productivity and fruits quality for cherry species. In 2011 (432,4 mm) and 2012 (446,6 mm) there were registered quantities below the multiannual limit (524,6 mm), getting a deficit of 92,2 mm in 2011 and 78,0 mm in 2012 (this climatic variability influences negatively the fruit’s growth) and in 2013 the multiannual was exceeded, being achieved 705,4 mm (a surplus of 180,8 mm). Analyzing the average productions on three years (the years XII-XIV from plantation), from the statistic point of view, we can see that the cultivars Margo (30,9 kg/tree) and Ludovic (19,9 kg/tree) registered positive production differences compared to the cultivars average. Under the aspect of the fruits weight (g) and of the equatorial diameter (mm), there were remarked the cultivars Alex (9,6 g and 24,8 mm), Ludovic (8,8 g and 24,1 mm) with positive significant differences compared to the witness and Paul (8,0 g with 22,9 mm), being significantly positive compared to the witness.
