The influence of biofertilization on the growth,yield and fruit quality of cv.Topaz apple trees
NPK humus UP vinassa apple yeast
2016/9/2
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...
Detection and molecular characterization of phytoplasmas infecting apple trees in Poland
identification PCR-RFLP sequencing phylogenetic analysis
2015/3/24
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 ...

Detection of Apple stem grooving virus in different tissues of apple trees throughout the year
Apple stem grooving virus tissue sampling RT-PCR ELISA reliability of detection
2015/1/30
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...

2015/1/30
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...
Influence of Training Systems on Leaf Mineral Contents, Growth, Yield and Fruit Quality of “Anna” Apple Trees
Anna apple tress training system leaf mineral contents fruit set yield fruit quality
2010/11/15
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...
