Abstract: Economically important viruses infect plums and other stone fruits cause lower yields, fruit size and quality and also affect its chemical composition. Fruits of the genetically modified (GM) plum 'HoneySweet' growing on trees deliberately infected with Plum pox virus (PPV), Prune dwarf virus (PDV) and Apple chlorotic leaf-spot virus (ACLSV) were analysed in detail to determine what effects these virus infections have on selected pomological traits, dissolved solids and titratable acids. Assessments of the fruits were made in the years from 2011 to 2014. The GM plum 'HoneySweet' was chosen for this experiment, and uninfected trees of the same variety in the same orchard were used as control. It was shown that there was no effect on dissolved solids resulting from PPV infections, either alone or in combination with the other viruses, but that there was a significant effect on levels of titratable acids where trees had been inoculated with all three viruses (treatment I). Regarding pomological traits, in most cases there were no significant effects seen to affect internal characteristics, only that in the assessments were lower although still of an acceptable quality for commercial fruit.

There are about ten species of apricot (Subg. Armeniaca Mill.) worldwide, among which nine species are native to China. Sharka disease caused by the Plum pox virus (PPV) is widely distributed in the main producing regions of apricot. In this study, linked simple sequence repeats (SSR) primers were used to detect allele variations potentially associated with PPV resistance among Chinese apricot germplasm resources, including 52 accessions belonging to Prunus armeniaca, 7 to Prunus mandshurica, 6 to Prunus sibirica, 4 to Prunus mume, 17 to other species or types. The allelic variation at loci with PPV resistance showed that these SSR markers linked to PPV resistance kept a relatively high level of diversity in Chinese apricot. The special alleles and genotypes only found in South China cultivars might reveal new PPV resistance sources. Some famous local cultivars of Chinese apricot might be considered as candidates for PPV resistance.

The objective of this study was to develop a screening test for the estimation of cut flower postharvest life and the response to exogenous ethylene of different carnation cultivars at an early stage of plant growth. Ethylene sensitivity and production in different cut flower cultivars was evaluated, and a similar response in the vegetative stage was studied. Also, the possible relationship between the morphological parameters of cuttings and flower postharvest life was studied. Ethylene production of cuttings may be a useful tool for estimating ethylene production of cut flowers. There is a strong relationship between cut flower vase life and the root length of cuttings, as well as cut flower ethylene sensitivity and the number of internodes the cuttings have. Applications of exogenous ethylene to cutting cultivars have an effect on the growth parameters of the cuttings, but the response to ethylene in cut flowers does not behave in the same way in the vegetative stage.

Marketable yield decreases according to the reduction of crop length caused by the increase of growth temperature. The nutritive requirements of storage onion are highest during the vegetative growth. The application of humic substances and the inoculation of mycorrhizae may enhance bulb growth and quality, mainly under stress conditions. Onion is a slow-growth, shallow-rooted crop with non-shading habitus and therefore its productivity is highly dependent on water availability in the soil, proper fertilization and weed control. The shelf-life of onion bulbs is a genetic trait, improvable by efficient crop and post-harvest management, and adequate conditions of bulb storage. The quality of storage onion bulbs is ascribed to several indicators, such as thiosulfonates, pyruvic acid, soluble solids, sugars, and many other biological compounds. This review is also focused on onion quality as affected by the interactions among genotype, environment, farming practices and post-harvest management.

It explains the causes of contaminated soils by winter salt management and principles of the toxic effect on plants. The paper summarizes the problem and brings solution. Town places with salt-contaminated soil should not be fitted with: spruce (Picea), pine (Pinus), linden (Tilia) and maples (Acer). On the other hand, resistant species are: ash (Fraxinus), poplar (Populus), willow (Salix), silverberry (Eleagnus), black locust (Robinia). Both lists of sensitive and salt-tolerant tree species have been presented. Salt-tolerant tree should be preferred before all the others species.

The shallot seems to be resistant against GCLV because none of the tested plants was infested by this virus. Other three viruses were found with an incidence ranging from 53% to 93% for genotypes and 48% to 87% for plants. Most of the tested shallot genotypes were simultaneously infected with two or three viruses. These results were compared with neighbouring collection of garlic where all four viruses were found widespread with an incidence ranging from 65% to 83% for genotypes and 39% to 61% for plants.
