摘要
该研究介绍了2017年在布加勒斯特农业经济科学与兽医大学园艺学院实验田种植的28个杏品种的行为。在Myrobalan 29C上嫁接的外国品种Saint-Julien A和GF 677分别种植在平行U的4.5 x 1.5 m和3.5 x 2.0 m处，三叉戟树冠的3.5 x 2.0米处。通过对树干横截面、树高、果枝数和长度的分析，评价了树木的植被生长。对初果产量进行了测定，并计算了产量指数。结果表明，生长差异与冠层、品种和所用砧木有关。给出了分析参数之间的相关性。因此，使用不同类型砧木的平行U和三叉戟两个树冠之间的差异表明了它们对杏树的年营养生长和生产力的影响。对两种油菜在杏园中应用的优缺点可以得出一些初步结论。
PRELIMINARY RESULTS REGARDING THE BEHAVIOUR OF SOME NEW APRICOT CULTIVARS IN BUCUREȘTI AREA
The study presents the behaviour of 28 apricot cultivars planted in 2017 in the
Experimental Field of the Faculty of Horticulture within the University of Agronomic
Sciences and Veterinary Medicine of Bucharest. The foreign cultivars grafted on
Myrobalan 29C, Saint Julien A and GF 677, were planted at 4.5 x 1.5 m and 3.5 x 2.0 m
for Parallel U and respectively, 3.5 x 2.0 m for Trident canopy. Trees vegetative
growth was evaluated by analysing the trunk cross section, tree height, fruiting
branches number and length. First fruit yield was heighted and the productivity index
was calculated. The results show differences in growth correlated with the canopy,
cultivars and used rootstocks. Correlations between analysed parameters are
presented. As a conclusion, the differences between the two canopies, Parallel U and
Trident, using different types of rootstocks show their influence on the annual
vegetative growth and on apricot trees productivity. Some preliminary conclusions
can be drawn regarding the advantages and disadvantages of using the two canopies
in apricot orchards.
