Apple Fruit Pectic Substances.
1. The pectic substances of apple have been extracted and separated into a pure pectinic acid and a neutral arabinan-galactan complex by precipitation of the acidic component with ethanol and with cetylpyridinium chloride. 2. The composition of the fractions has been determined. The pectinic acid contained galacturonic acid, arabinose, galactose, rhamnose, xylose and several trace sugars. 3. Tr...
متن کاملMitigation of effects of extreme drought during stage III of peach fruit development by summer pruning and fruit thinning.
A water deficit during stage III of fruit growth was established with the aim of determining if it is possible to achieve an improvement in tree water status by summer pruning and fruit thinning. The experiment was set up as a randomized block split-plot design across trials (irrigation) where pruning was assigned to the main plot and fruit thinning to the sub-plots. The irrigation treatments w...
متن کاملAncestral state reconstruction infers phytopathogenic origins of sooty blotch and flyspeck fungi on apple.
Members of the sooty blotch and flyspeck (SBFS) complex are epiphytic fungi in the Ascomycota that cause economically damaging blemishes of apples worldwide. SBFS fungi are polyphyletic, but approx. 96% of SBFS species are in the Capnodiales. Evolutionary origins of SBFS fungi remain unclear, so we attempted to infer their origins by means of ancestral state reconstruction on a phylogenetic tre...

متن کاملeffect of summer pruning and spray with calcium on mineral composition and fruit quality of kiwifruit cv. hayward
summer pruning and calcium spray could improve kiwifruits quality. in this study, effect of summer pruning in two times, 2 and 15 days after petal fall alone or in combination with %1 calcium chloride spray on fruit quality and mineral elements contents of ‘hayward’ kiwifruit was investigated. calcium sprayed four times 90 days after petal fall with 15 days intervals. the results showed that su...
