Micropropagation of hazelnut (Corylus avellana
L.) is typically difficult because of the wide variation
in response among cultivars. This study was designed to
determine the required mineral nutrient concentrations for
micropropagation of C. avellana cultivars using a response
surface design analysis. Driver and Kuniyuki Walnut
(DKW) medium mineral nutrients were...

Inorganic nitrate (NO₃⁻) and ammonium (NH₄⁺) are the two major components in nitrogen (N) nutrition of typical tissue culture growth media, and the total amounts and ratios influence both shoot induction and differentiation. This study was designed to determine the optimal N requirements and interactions of NH₄⁺×NO₃⁻ to complete the...
Many hazelnut (Corylus avellana L.) cultivars
fail to thrive in vitro on standard growth medium and the
reasons for poor growth are not well understood. Our initial
study of five C. avellana cultivars showed that changes in
the mineral nutrients of Driver and Kuniyuki walnut
(DKW) medium, including doubling the...

In vitro propagation is important for rapid multiplication of a wide range of nursery crops, including
red raspberries. The genetic variation of the many red raspberry cultivars makes it difficult to use one
growth medium for all. Although some cultivars grow well on Murashige and Skoog (1962) medium
(MS), others...
Abnormal physiological responses of plant cultures such as shoot tip necrosis, callus, and hyperhydricity are some of the most difficult challenges in shoot micropropagation, and their causes are not well understood. Five Murashige and Skoog mineral salt factors, which influence the growth of pear shoot cultures, were tested in a...
Pear accessions and species show a broad response to tissue culture media due to the wide genetic diversity that exists in the available pear germplasm. An initial study of mineral nutrition using a systematic response surface approach with five Murashige and Skoog medium mineral stock solutions indicated that the mesos...
Mineral nutrition in the media used for growth of in vitro plants is often difficult to optimize due to complex chemical interactions of required nutrients. The response of plant tissue to standard growth media varies widely due to the genetic diversity of the plant species studied. This study was designed...
Most blackberry and raspberry (Rubus) seed exhibit delayed or poor germination because of a deep double dormancy. The objective of this study was to improve seed scarification and germination protocols for the diverse Rubus species in two subgenera often used for breeding improved cultivars. We also defined the germination potential...
