Genotype-by-environment and QTL-by-environment interactions in sweet cherry ( L.) for flowering date.

In sweet cherry ( L.), flowering date is strongly dependent on the environment conditions and, therefore, is a trait of major interest for adaptation to climate change. Such trait can be influenced by genotype-by-environment interaction (G×E), that refers to differences in the response of genotypes to different environments.

Biochemical Characterization of Black and Green Mutant Elderberry during Fruit Ripening.

The content of sugars, organic acids, phenolic compounds and selected enzyme activities in the anthocyanin pathway were analyzed in NIGRA ( var. -black fruits) and VIRIDIS ( var. -green fruits) fruits over four stages of ripening.

The Distribution of Minerals in Crucial Plant Parts of Various Elderberry ( spp.) Interspecific Hybrids.

In view of growing requirements of the food industry regarding elderberries (genus ), a need to increase their productivity and improve their chemical composition has emerged. With this purpose in mind, numerous elderberry interspecific hybrids have been created. In the present work, the content of minerals in their crucial plant parts was studied.

Comparison of major taste compounds and antioxidative properties of fruits and flowers of different Sambucus species and interspecific hybrids.

Differences in the content of sugars, organic acids, total phenolics and antioxidative activity have been evaluated among three different elderberry species (Sambucus nigra, Sambucus cerulea, Sambucus javanica) and seven interspecific hybrids. The highest content of sugars has been determined in the fruits of JA×CER hybrid and the lowest in fruits of (JA×NI)×cv. Black Beauty hybrid.

Fruit Phenolic Composition of Different Elderberry Species and Hybrids.

Unlabelled: The aim of this study was to investigate a detailed composition and content of phenolic compounds in fruits of 4 elderberry species (Sambucus nigra, S. cerulea, S. ebulus, and S racemosa) and 8 interspecific hybrids.

Variation of mineral composition in different parts of taro (Colocasia esculenta) corms.

Taro (Colocasia esculenta) is an important root crop in the humid tropics and a valuable source of essential mineral nutrients. In the presented study, we compared the mineral compositions of four main parts of taro corm: the upper, marginal, central and lower (basal) parts. The freeze-dried taro samples were analysed for eleven minerals (K, P, Mg, Ca, Zn, Fe, Mn, Cu, Cd, Pb and Cr).

Investigation of anthocyanin profile of four elderberry species and interspecific hybrids.

A total of 19 different anthocyanins have been detected in four elderberry species and eight hybrids and quantified with the use of HPLC-MS(n). The profile and content levels of anthocyanins varied considerably among the analyzed elderberry species and hybrids. Cyanidin-3-O-sambubioside and cyanidin-3-O-glucoside were the most abundant anthocyanins in Sambucus nigra fruits.

Effect of soil management systems on erosion and nutrition loss in vineyards on steep slopes.

Green cover in vineyards on steep slopes may play an important role in the reduction of soil erosion. The main objective of this study was to investigate the effect of a permanent green cover (PGC) on soil erosion, together with any loss of nutrients, and to compare it with periodic soil tillage (PST). PST took place in the spring (May) and summer (August), in each second area between rows, in a vineyard with permanent green cover.

Thermogenesis and flowering biology of Colocasia gigantea, Araceae.

The thermogenesis and flowering biology of Colocasia gigantea (Blume) Hook. f. were studied from December 2005 to February 2006 on Espiritu Santo, Vanuatu (South Pacific).
