摘要

In production of high quality certified fruit trees, new tree growing methods utilizing plant growth regulators (PGRs) are increasingly being used. The main benefit of using PGRs lies in stimulating branching of one-year grafted fruit trees. In our experiment we used two apple cultivars: a well-branching 'Galaval' and a very poorly branching cultivar 'Rubinola'. From cultivars of European pear, we used 'Decora' as the well-branching cultivar and 'Bohemica' as a poorly branching cultivar. We used theJapanese pear cultivar 'Hosui' to verify the basic reaction to application of the commercial products of PGRs. For the purpose of our experiments we used commercially available products Globaryll 100 (6-BAP 10%, from Globachem, Belgium), Progerbalin LG (GA4 + GA7 1.88% and 6-BAP 1.88%, from L. Gobbi, Italy), GIBB plus (GA4 + GA7 1%, Globachem, Belgium). In addition, we also prepared mixed PGR solutions containing substances such as TIBA, 4-CPPU, paclobutrazol, ethephon, 6-BAP, gibberellic acidi+7, naphthylphtalamic acid, putrescine HCL and 24-epibrassinolide (all products from Duchefa, the Netherlands). The number of branches formed on trees of cultivar 'Galaval' after application of the different PGR products and solutions ranged between 7.3 and 17.1branches tree-1. The best results in stimulation of branching of 'Galaval' trees was achieved by application of Progerbalin LG + 4-CPPU + putrescine HCL mixture. Branching in the range of 1.0-11.7 branches tree1 was achieved in cultivar 'Rubinola', wherethe most effective branching treatment was Globaryll 100 (from the non-commercial mixtures the most efficient was the application of ethephon + 6-BAP + putrescine HCL). With the European pear cultivars, the achieved values were 6.1-39.9 branches tree1 after application of different PGR products and solutions, where the best results were obtained by the application of ethephon + 6-BAP + putrescine HCL mixture. In trees of 'Bohemica' cultivar the branching achieved 7.7-15.2 branches tree S depending on used PGR product or mixture. In trees of 'Hosui' cultivar the results were 0.5-2.6 of short brachyblasts tree-1 when Progerbalin LG was applied. Application of the other products and mixtures was less efficient. We also obtained interesting results concerning features such as length of new branches, the overall tree height and thickness of the trunk at the root crown and under the first ramification. Significant differences were observed in the influence of the tested PGR products and mixtures over the parameters of the nursery plants.

Gobbi，意大利），Gibb加（Ga4 + Ga7 1％，Globachem，比利时）。此外，我们还制备了含有TIBA，4-CPPU，PACLOBUTRAZOL，ETHEVEHON，6-BAP，赤霉素+ 7，萘基苯胺酸，PUTRESCINE HCL和24倍溴醇（荷兰的所有产品）的物质的混合PGR溶液。在施用不同的PGR产品和溶液后形成的树枝上形成的分支数，范围为7.3和17.1banches-1。通过施用Progerbalin Lg + 4-CPPU + Putrescine HCl混合物，实现了刺激“Galaval”树分支的最佳结果。在1.0-11.7分支树中的分支在品种的“rubinola”中实现，而最有效的分支治疗是Gromaryla100（来自非商业混合物，最有效的是Ethephon + 6-Bap + Putrescine HCL的应用）。随着欧洲梨品种，在应用不同的PGR产品和解决方案后，达到的值为6.1-39.9分支树1，其中通过应用Ethephon + 6-Bap + Putrescine HCl混合物获得了最佳结果。在“波西米加”品种树上，该分支达到7.7-15.2分支树S取决于二手PGR产品或混合物。在“Hosui”品种树上，当施用Progerbalin Lg时，结果为0.5-2.6的短毛细胞树-1。其他产品和混合物的应用效率较低。我们还获得了有趣的结果，如新分支的长度，根冠上的躯干的整体树高度和厚度等特征的有趣结果。在测试的PGR产品的影响下观察到显着差异，并在苗圃植物参数上的混合物的影响。
