Subject:
Prunus cerasifera; acclimation; autotrophs; carbon; environmental factors; micropropagation; peat; photosynthesis; plantlets; researchers; ribulose-bisphosphate carboxylase; rooting; rootstocks; sucrose
Abstract:
... In vitro cultured plantlets have heterotrophic development, relying on the use of exogenous sugars as a carbon source for growth. During the acclimatization stage, plantlets are constrained to grow photoautotrophically, i.e. to synthesize carbohydrates through their own photosynthesis. Many researchers suggested that the photosynthetic competence of plants, when transferred to soil, might be an im ...

Abstract:
... The effect of various concentrations of auxin and different basal culture media on the rooting of pistachio micro-shoots were investigated. The results showed that micro-shoots cultured on half strength DKW medium supplemented with 2 mg/l IBA plus 0.01 mg/l NAA gave 100% rooting and was the best treatment. Rooted-shoots were readily established in peat: perlite (1:1) mixture and plantlets were acc ...

Abstract:
... Perennial fruit trees such pear require a long-term effort for breeding because of their long generation time and high level of heterozygosity. The production of haploid plants should offer new possibilities for genetic studies and breeding. Procedures for the production of haploid plants from peat have been developed. Oryzalin which was an efficient mitotic agent for doubling chromosomes of haplo ...

Abstract:
... During the last five years the Vivai Battistini dott. Giuseppe has increased the production of Pyrodwarf ('Old Home' x 'Bonne Luise D'Avranches') and Cydomalus (Malus communis x Cydonia oblonga) rootstocks. Experiments were carried out to improve "in vitro" root development, by modification of the substrates (agar, vermiculite, peat, pumice + vulcanite in different combination) plus evaluation of ...

Abstract:
... The highbush blueberry in the natural environment is generally mycorrhized by Ascomycetes of the genus Hymenoscyphus; but probably also other mycorrhizal fungi are involved. The aim of the research was to find the best procedures to inoculate the roots of micropropagated plantlets of highbush blueberry with selected symbiotic fungi grown in vitro in order to obtain plants inoculated only with one ...

Abstract:
... Different results have been obtained by numerous authors in fertilization trials on blueberry. The role of macro and micro-elements has been scarcely investigated in soil-less systems, where the interference of abiotic (pedologic) and biotic (mycorrhiza) factors is prevented. This research was initially carried out using micropropagated plants grown on sterile peat, not contaminated with mycorrhiz ...

Abstract:
... Micro propagated plants of the summer fruiting variety ‘Tulameen’ were planted in June 1999 in peat in 10 l containers and grown under tunnels. In 2000 these plants were examined for their suitability for advanced and delayed cropping. Production level, fruit grading, average fruit weight, fruit quality and production period were evaluated. As a control a seasonal crop was obtained by growing the ...

In the opencast peat pits the growing substrate had a very low nutrition content, therefore the use of fertilisers is needful. In a production field of lowbush blueberry (Vaccinium angustifolium Ait.), the influence of foliar fertiliser Ca(NO3)2 and two complex fertilisers (12% P, 18% K and 10% N, 20% P, 20% K) on g ...
