Two polygalacturonases (PG I and PG II) have been separated from extracts of ripe peaches (Prunus persica) by chromatography on Sephadex G-100. PG I hydrolyzes polygalacturonic acid from the nonreducing ends of the molecules, releasing galacturonic acid as the product. It functions optimally at pH 5.5, requires Ca(2+) for activity, and hydrolyzes low molecular weight substrates most rapidly. In...

Abstract Hundred gram of large peach seeds were weighted and used as dried clean seeds. Part was grinding sieved to obtain fine size granules, with 3 mm an average. This grain is suitable for absorption ensures that the particles remain completely did not dissolved or passes water through contact treatment. Water samples collected from sources municipal uses in Mosul city, artesian wells differ...

In South Asian countries, the lucrative production of peaches has been seriously threatened by an assortment biotic stresses especially nematodes. This situation compromises achievement sustainable development goals (SDGs) related to food security and zero hunger. Recently under changing climate, root-knot nematodes genus Meloidogyne have emerged as most damaging phytopathogenic nematodes, whil...
