For breeding purposes, the number of neo-tetraploids of apple cultivars have been derived by in vitro technique. The first attempts at rooting and acclimatization of tetraploid shoots failed. The aim of the study was to develop an effective method for rooting microcuttings of apple neo-tetraploids. In the first stage of the study, in vitro rooting method was optimized for the shoots of diploid donor...
Identification of cultivars is essential both in breeding and to settle cultivar disputes. The purpose of the study has been to examine cultivar identities based on absorption spectra of plant pigments and to confirm a genetic stability with SCoT and RAPD molecular markers in new Polish lines of Chenopodium quinoa Willd. Spectral analysis of pigments extracted from plant inflorescences in quinoa gives...
Silybum marianum (milk thistle) is among the top selling herbal products in the U.S., in Italy and in other countries. Despite its economic importance as an officinal and medicinal species, only few improved genotypes exist and the species is still marked by traits that are typical of non-domesticated plants. Based on this evidence, further genetic improvement is required for the complete exploitation...
Micropropagation of strawberry (Fragaria × ananassa Duch.) is a widely used technique to produce plantlets in commercial horticulture. Unfortunately, in contrast to propagation based on runners, it is also an expensive method and may lead to obtaining plants with changed phenotype. In order to reduce such problems, the influence of chemical method of medium sterilization (application of commercial...
Honeyberry’s popularity has been increasing because of its valuable traits: nutritional value of fruits (a high amount of ascorbic acid, potassium and polyphenolic compounds), early ripening (14 days before strawberry), exceptional hardiness and easy cultivation. However, there is still little known about the pollination biology of this species, which is essential for practical breeding purposes....
Indian jujube (Zizyphus mauritiana Lamk.) is mostly cultivated in tropical and sub-tropical regions of the world. Many native and exotic jujube cultivars are grown for fruit production in Pakistan. However, little research work has been conducted on various aspects of jujube i.e. morphological and biochemical characterization of available germplasm. Therefore, fruits of thirteen genotypes were collected...
