Orchard performance and fruit quality of 50 apple cultivars grown or tested in commercial orchards of the Czech Republic

open access: yesHorticultural Science, 2007
Tree vigour, occurrence of mildew and scab, yields, yield efficiency, fruit weight, flesh firmness and soluble solids content of apple trees on M 9 rootstock were monitored between 1998-2005 in 42 commercial orchards situated in all the major growing ...

Selection of the most efficient wavelength bands for ‘Jonagold’ apple sorting [PDF]

open access: yesPostharvest Biology and Technology, 2003
This paper presents a method based on quadratic discriminant analysis to select the best filters for detecting a wide range of defects in 'Jonagold' apple fruit using a multi-spectral vision system. Reflectance spectra of damaged and sound tissue were recorded using a visible/NIR spectrometer.

The combination of NAD and NAA for thinning of ’Jonagold’ and ‘Idared’ apple trees

open access: yesActa Agriculturae Slovenica, 2002
Mature apple trees ‘Jonagold’/M.9 and ‘Idared’/M.9 were thinned with different concentrations of naphthaleneacetamid (NAD, - 25 ppm, 50 ppm and 100 ppm) at petal fall time, with 1-naphthaleneacetic acid (NAA, - 6 ppm and 12 ppm) at 10 mm fruitlet ...

The influence of the two-spotted spider mite (Tetranychus urticae Koch.) and irrigation on yield of 5-years-old apple trees

open access: yesActa Agrobotanica, 2013
The influence of the two-spotted spider mite (Tetranychus urticae) on yield of apple trees was investigated. The experiment was conducted on rrigated and non-irrigated 5-years-old apple trees of 'Close' and 'Jonagold' cultivars grafted on M.9.

Selection Models for the Internal Quality of Fruit, based on Time Domain Laser Reflectance Spectroscopy [PDF]

open access: yes, 2004
Time domain laser reflectance spectroscopy (TRS) was applied for the first time to evaluate internal fruit quality. This technique, known in medicine-related knowledge areas, has not been used before in agricultural or food research.

CALLUS FORMATION IN BUD UNIONS OF `JONAGOLD' ON `MARK' ROOTSTOCK [PDF]

open access: yesHortScience, 1990
`Mark' rootstock is a relatively new dwarfing rootstock that induces precocity in apple trees. While `Mark' has desirable horticultural characteristics, it has been difficult to propagate in some areas of the United States. To determine the optimum budding date at two climatically diverse locations, `Jonagold' buds were chip-budded onto `Mark ...

Apple burrknots involved in trunk canker initiation and dying of young trees

open access: yesPlant Protection Science, 2009
Conditions associated with an unusually high occurrence of burrknots in two young commercial apple orchards at two locations, Těšetice and Stošíkovice, South Moravia, the Czech Republic, were analysed.
