The resilient polymer tattoos placed on the leaves allow for "frequent and long-term monitoring of cellular ozone damage in economically important crops such as grapes and apples," Andrew says."We sel...
This study was conducted in the period 2010–2015 to assess the influence of rootstocks on the growth and fruiting of apple trees of the ‘Golden Delicious Reinders’ cultivar. The experiment was conduc...
Maiden apple trees of cv. Topaz were planted in 2011. In the spring of 2014, chemical fertilization (NPK) and various bioproducts: Fertigo, Micosat, Humus UP, Humus Active + Aktywit PM, Aktywit PM, Bi...
During 2010–2012, samples from 225 apple trees growing in six regions of Poland were tested for phytoplasmas. 16S rRNA gene and 16S-23S spacer region sequences were amplified from total DNAs prepared ...
During the 2005–2007, we identified six species of predatory mites in the integrated and an ecological orchard: Phytoseius echinus, Phytoseius macropilis, Euseius finlandicus, Typhlodromus pyri, Par...
The suitability of different apple tissues for Apple stem grooving virus (ASGV) detection throughout the year was checked by RT-PCR and ELISA. Detectable amounts of ASGV were generally found in all ti...
The presence of phytoplasmas in apple trees with proliferation symptoms, rubbery wood symptoms and no symp-toms was determined by using polymerase chain reaction assays with primers amplifying phytopl...
The influence of two training systems (tiller, and open central leader) on leaf mineral contents, growth, fruit set, yield, and fruit quality of “Anna” apples cultivar was estimated in the experiment ...
The effects of calcium formate application on apple fruit (Malus domestica Borkh.) set were examined. Spraying with calcium formate after full bloom reduced the fruit set. Spraying caused injury to st...
Leaf distribution, light environmental condition and dry matter production of 3-year-old 7 columnar type apple strains on Marubakaido (Malus. prunifolia Bork. var. ringo Asami) and 6 normal type apple...
The mechanism of photosynhetic inhibition in sink-limited leaves of young apple trees by continuous light (CL) was investigated. By 3 days after CL, the photosynthetic rate (A), stomatal conductance a...
The growth and graft union strength of apple trees grafted on extremely dwarfing rootstocks, JM5 and M. 27, were investigated. The scion growth of ‘Tsugaru’, ‘Sansa’, ‘New Jonagold’, ‘Hokuto’, ‘Orin’ ...
The length and position distribution of 1-year-old bearing wood were compared among 3 varieties and between pruned and unpruned apple trees. In pruned trees, the proportion of long (10 cm<) and short ...
Characteristics of tree growth, yield efficiency and dry matter production (DM) were studied using the columnar-type apple tree ‘Maypole’ grafted on Marubakaido (Malus. prunifolia Bork. var. ringo Asa...
The effect of planting density (330–3178 trees/ha) on net production (t DW/ha/y) and partitioning was studied in 11 to 13-year-old ‘Starking Delicious’ apple trees on M.9, M.26, M.7 and MM.106 without...
