Chlorophyll fluorescence in two strawberry (Fragaria x ananassa Duch.) cultivars Fluorescencja chlorofilu u dwóch odmian truskawki (Fragaria x ananassa Duch.)
The study of chlorophyll fluorescence (CF) parameters i.e.: Fo, Fm, Fv/Fm, Y, qP, qN, F’o, F’m was conducted in two strawberry cultivars ‘Honeoye’ and ‘Teresa’. Measurements of their values were done twice: in an early autumn and late spring. Fluorescence of five dark-adapted mature leaves derived from each cultivar was measured in the laboratory at room temperature with the use of a portable p...
متن کاملEFFICACY OF RESISTANCE SELECTION TO VERTICILLIUM WILT IN STRAWBERRY (Fragaria x ananassa Duch.) TISSUE CULTURE
The soil-borne pathogenic fungus Verticillium dahliae Kleb. causes economic losses in crops in temperate regions of the world and hence is the most studied species. Strawberry (Fragaria x ananassa Duch.) belongs to plant species susceptible to Verticillium dahliae, although the response to infection caused by this pathogen is varied and depends on the cultivar. Due to a lack of efficient method...
متن کاملNew findings in strawberry (Fragaria × ananassa Duch.) anther culture
In this research, some independent experiments were carried out for investigating the effects of microspore developmental stage, bud pretreatments (cold, heat and Ca), and embryo induction medium on anther culture of some strawberry cultivars. The results showed that the percentages of responsive and embryogenic anthers in cultivar Paros in liquid medium were influenced not only by different de...
متن کاملStrawberry (Fragaria ·ananassa Duch.) Growth and Productivity as Affected by Temperature
Thermotolerance of photosynthesis and productivity in Chandler and Sweet Charlie strawberry plants (Fragaria ·ananassa Duch.) exposed to three temperature regimes was studied. Net CO2 assimilation rate (A), variable chlorophyll fluorescence (Fv), efficiency of photosystem II (Fv/Fm), relative chlorophyll content, plant growth, and fruit yield and quality weremeasured. High temperature (40 C day...
متن کاملSalinity, Supplementary Calcium and Potassium Effects on Fruit Yield and Quality of Strawberry (Fragaria ananassa Duch.)
Fruit set and quality in strawberry cv. Selva were influenced by salinity (NaCl) and supplementary calcium and potassium (CaSO , CaCl , K SO ) treatments applied to the root medium of plants growing in 4 2 2 4 soilless culture under heated greenhouse conditions. Yield components such as primary fruit weight and fresh fruit weight (at harvest time) and fruit number were higher in control and the...
