Genetic diversity in yellow passion fruit populations
The genetic diversity in yellow passion fruit genotypes from populations of different origins (Campos dos Goytacazes, Itaperuna and São Francisco de Itabapoana , Rio de Janeiro State, Brazil), was quantified. The following traits were evaluated in two environments (Macaé and Campos dos Goytacazes): fruit weight, mean number of fruits, fruit length, equatorial fruit diameter, rind thickness, bri...
متن کاملDetection of a resistance gradient to Passion fruit woodiness virus and selection of 'yellow' passion fruit plants under field conditions.
Productivity of 'yellow' passion fruit (Passiflora edulis Sims. f. flavicarpa O. Deg.) is reduced by infection with Cowpea aphid-borne mosaic virus (CABMV). We examined resistance in 72 yellow passion fruit plants grown from open-pollinated commercial seed. Plants were mechanically inoculated with CABMV virus and maintained in the field in order to select contrasting genotypes for resistance. I...
متن کاملBlueberry fruit response to postharvest application of ultraviolet radiation
Blueberries (Vaccinium corymbosum, cvs. Collins, Bluecrop) were exposed to ultraviolet light-C (UV-C) radiation treatments from 0 to 4 kJ/m2 rior to 7 days storage at 5 ◦C plus 2 days at 20 ◦C, 90% RH. Weight loss and firmness were not affected by light treatment. Decay incidence from ipe rot (Colletotrichum acutatum, syn. C. gloeosporioides) on fruit was decreased by 10% with 1–4 kJ/m2 UV-C li...
متن کاملA Study of Bacterial Sensitivity to Ultraviolet Radiation'
Previous studies ( Bachem and Dushkin, 1932) on the reactions of bacteria to ultraviolet light have demonstrated that these organisms re spond with different sensitivities according to various experimental con ditions. Variables, such as the wave length utilized, the age of the bac terial culture, and the temperature at which the organisms are maintained will all be reflected in the bacterial s...
متن کاملAmplified RNase H activity in Escherichia coli B/r increases sensitivity to ultraviolet radiation.
Strains of E. coli B/r transformed with the plasmid pSK760 were found to be sensitized to inactivation by ultraviolet radiation (UV) and to have elevated levels of RNase H activity. Strains transformed with the carrier vector pBR322 or the plasmid pSK762C derived from pSK760 but with an inactivated rnh gene were not sensitized. UV-inactivation data for strains having known defects in DNA repair...
