Abstract:

The article presents the results of the research on the influence of budding height and the method of bi-axis formation on quality indicators of young bi-axis apple trees of ‘Florina’ cultivar on B.118 rootstock in conditions of fruit trees nursery of educational and production department of Uman NUH. Budding with chip was made at the period of late July and early August at a height of 10 and 20 cm (the control). The formation of two axes was made with the help of budding in two ways: budding with one bud with pinching of a shoot at a height of 10 cm (the control); budding with one bud with pinching of a shoot at a height of 20 cm, budding with two buds that are opposite set, and budding with two buds that are alternate set and have a shift on a rootstock axis up to 5 cm due to each other.

The maximum trunk diameter was observed in young bi-axis apple trees that have alternate and opposite ways of budding with the help of two buds at a height of 10 cm above ground level. The reduction of the budding height up to 10 cm above ground level did not affect the height of the young bi-axis apple trees, though it had a significant effect on axis elongation. It was defined that one-dimensional formation of both axes occurred with the even distribution of length and number of branches on each were observed on young apple trees that had opposite budding with two buds at the above ground level height of 10 cm. The largest number of differentiated generative buds was observed on young trees that had opposite budding with two buds at the above ground level height of 10 and 20 cm.

Abstract:

Valorization of local olive cultivars is a key factor for the medium-term development strategy of the Italian olive agroindustry. This involves enhancements in both, cultural practices and nursery techniques. The aim of this research was the evaluation in nursery, on vegetative growth and root development of young olive plants, of two different treatments: substrate enrichment with Osmocote®, a slow-release fertilizer, and Trianum-P a Trichoderma harzianum based biostimulant applied as foliar spray. The trial was carried out on Rotondella and Salella,
two autochthonous olive cultivars from the Campania region (southern Italy). Central axis height, number and length of lateral shoots, leaf number and trunk base diameter were monitored during the experiment. Eight months later, all plants were uprooted, and further parameters were measured: total leaf area, trunk cross sectional area (TCSA), fresh and dry weight of the leaves, shoots, trunk, roots, and total dry matter. The canopy/root ratio (C/R) was also determined. Overall, the Osmocote® treatment caused a significant increase in the vegetative growth parameters for both cultivars, with a more evident effect on the development of the canopy organs. The observation reported in the present work can represent a convenient piece of information particularly in relation to stress resilience in nursery production.

Abstract:

Apple rootstocks P 59, P 22, P 2, P 60, M.9, M.26, MM.106, B.118 (54–118), B.396 (62–396) and ‘Antonowka‘ seedlings were tested at the Lithuanian Institute of Horticulture in fresh soil and in soil previously used for an apple nursery. Replanting had a negative effect on the development of apple tree propagation material in the nursery. Bud survival of cv. ‘Sampion’ decreased by 24% compared to those in fresh soil. Other tree growth parameters were suppressed as well: tree height by 29%, trunk diameter by 24%, average leaf area by 28%, and absolutely dry leaf weight by 33%. Combining all parameters it could be concluded that apple trees of cv. ‘Sampion’ on P 59 and P 60 rootstocks are the most sensitive to soil exhaustion, whereas trees on P 2 and B.396 rootstocks show tolerance to replanting.
