Improvement of grafting procedures for the ornamental species: II. Abies concolor [(Gord. & Glend.) Lindl]

The achieved results concerning the grafting silver-fir - Abiesconcolor [(Gord. & Glend.) Lindl] scions on white-fir (Abies alba Mill.)rootstocks are reporting in this article. The double-side-veneer grafting method and the plastic tape and the ecological Ceraltin® wax were applied in four experimental variants. The side-veneer-grafting method and the classic materials, such as raffia and the hot wax were used at the two controls involved in this experiment. The grafting success expressed in percents, were transformed in arcsin square root of percent values, and a two-way analysis of variance was performed. Highly significant (p <0.001) statistical differences were found between grafting variants, including controls. The Duncan Multiple Range Test showed that the four experimental grafting variants were highly significantly (p < 0.01) better than the two controls. The grafting success of the best experimental variant has surpassed the two controls by 129 and 153%, respectively.Consequently, the double-side-veneer grafting method, the new developed plastic tape and the ecological Ceraltin® wax have contributed to this grafting success owing to which they are recommended to be used for grafting silver-fir ornamental trees

Improvement of grafting procedures for the ornmental species: I. Picea pungens Engelm. var. glauca Regel

In order to get ornamental trees for landscaping, Colorado blue spuce (Picea pungens Engelm. var. glauca Regel) scions were grafted on Norway spruce (Picea abies (L.) Karst.) rootstocks.An original double-side-veneer grafting method was applied in five experimental or basic variants. The plastic tapes and the ecological Ceraltin® wax developed by the Research and Development of Bio-stimulators (CCDB) BIOS Cluj were tested. In addition, two controls in which the classic raffia and the traditional hot wax and the classic side-veneer-grafting method were used. The obtained results, expressed in percents, were transformed in arcsin square root of percent values, and then a two-way analysis of variance (ANOVA) was used. Highly significant (p < 0.001) statistical differences were found between all grafting variants, including controls. The Duncan test proved that original double-side-veneer grafting method and the new developed materials, i.e. plastic tapes and the ecological Ceraltin® wax have contributed in getting a better grafting success compared to the controls.Thus, the double-side-veneer grafting method and the two grafting materials are highly recommended to be used in getting grafted Colorado blue spuce ornamental trees

Abstract. The achieved results concerning the grafting silver-fir -Abies concolor [(Gord. &amp; Glend.) Lindl] scions on white-fir (Abies alba Mill.) rootstocks are reporting in this article. The double-side-veneer grafting method and the plastic tape and the ecological Ceraltin ® wax were applied in four experimental variants. The side-veneer-grafting method and the classic materials, such as raffia and the hot wax were used at the two controls involved in this experiment. The grafting success expressed in percents, were transformed in arcsin square root of percent values, and a two-way analysis of variance was performed. Highly significant (p &lt; 0.001) statistical differences were found between grafting variants, including controls. The Duncan Multiple Range Test showed that the four experimental grafting variants were highly significantly (p &lt; 0.01) better than the two controls. The grafting success of the best experimental variant has surpassed the two controls by 129 and 153%, respectively. Consequently, the double-side-veneer grafting method, the new developed plastic tape and the ecological Ceraltin ® wax have contributed to this grafting success owing to which they are recommended to be used for grafting silver-fir ornamental trees

The achieved results concerning the grafting silver-fir - Abies concolor [(Gord. &amp; Glend.) Lindl] scions on white-fir (Abies alba Mill.) rootstocks are reporting in this article. The double-side-veneer grafting method and the plastic tape and the ecological CeraltinŽ wax were applied in four experimental variants. The side-veneer-grafting method and the classic materials, such as raffia and the hot wax were used at the two controls involved in this experiment. The grafting success expressed in percents, were transformed in arcsin square root of percent values, and a two-way analysis of variance was performed. Highly significant (p &lt; 0.001) statistical differences were found between grafting variants, including controls. The Duncan Multiple Range Test showed that the four experimental grafting variants were highly significantly (p &lt; 0.01) be-tter than the two controls. The grafting success of the best experimental variant has surpassed the two controls by 129 and 153%, respectively. Consequently, the double-side-veneer grafting method, the new developed plastic tape and the ecological CeraltinŽ wax have contributed to this grafting success owing to which they are recommended to be used for grafting silver-fir ornamental trees.</span

In order to get ornamental trees for landscaping, Colorado blue spuce (Picea pungens Engelm. var.glauca Regel) scions were grafted on Norway spruce (Picea abies (L. Karst.) rootstocks. An original double-side-veneer grafting method was applied in five experimental or basic variants. The plastic tapes and the ecological Ceraltin wax developed by the Research and Development of Bio-stimulators (CCDB) BIOS Cluj were tested. In addition, two controls in which the classic raffia and the traditional hot wax and the classic side-veneer-grafting method were used. The obtained results, expressed in percents, were transformed in arcsin square root of percent values, and then a two-way analysis of variance (ANOVA) was used. Highly significant (p &lt; 0.001) statistical differences were found between all grafting variants, including controls. The Duncan test proved that original double-side-veneer grafting method and the new developed materials, i.e. plastic tapes and the ecological Ceraltin wax have contributed in getting a better grafting success compared to the controls.Thus, the double-side-veneer grafting method and the two grafting materials are highly recommended to be used in getting grafted Colorado blue spuce ornamental trees.</span
