Sweet Cherry Cultivars Vary in Their Susceptibility to Spring Frosts

Strawberry Cultivars Vary in their Resistance to Northern Lesion Nematode.

The genetic diversity of commercial cultivars of strawberry Fragaria x ananassa from various parentages, as expressed by their resistance to the northem lesion nematode Pratylenchus penetrans, was evaluated in nematode-infested field plots for two growing seasons. Data taken for each plant in each season included soil nematode Pi and Pf, end-of-season nematode numbers in each entire root system...

Behavior of Some Sweet Cherry Cultivars on Mazzard Rootstock on Heavy and Acidic Soil

Over 60% Serbian soils are heavy, shallow and acidic, especially in west part of this country. Basically, Serbian fruit production is mainly represented in these conditions which are not favorable for intensive fruit growing. However, repair of these soils is a long and very expensive process. Regarding to this, one of the real ways to overcome this problem faster and cheaper is to grow toleran...

Genistein isoflavone glycoconjugates in sour cherry cultivars

Activity and expression of polygalacturonase vary at different fruit ripening stages of sweet pepper cultivars.

Activity and expression of polygalacturonase (PG), a hydrolytic enzyme involved in ultrastructural changes in the pericarp of sweet pepper (Capsicum annaum), were investigated at different ripening stages of the pepper cultivars Mandi and Talanduo. Molecular cloning of CaPG was carried out by constructing a cDNA library from three stages of fruit ripening. Morphological determination, PG ...

Soluble Sugars and Sucrose-Metabolizing Enzymes Related to Cold Acclimation of Sweet Cherry Cultivars Grafted on Different Rootstocks

The bark tissues were collected from 4-year-old sweet cherry trees cvs. 0900 Ziraat and Lambert grafted on Gisela 5 and Mazzard rootstocks in cold-acclimated (CA) and nonacclimated (NA) stages. Bark tissues subjected to 4 °C and -5 °C injured to a limited extent in both stages. However, more than 50% injury occurred by temperatures equal to or colder than -15 °C only in NA period. Total soluble...
