The content and homologue composition of alkylresorcinols were investigated in rye seedlings (Secale cereale L.) treated with benzimidazole fungicides and grown for 5 days under various thermal and light conditions. The fresh and dry biomasses of green and etiolated plants were greatly increased by benomyl and carbendazim at 29 °C. At 22 and 15 °C benomyl had an inhibitory action on growth of r...
Crop residues are potential biofuel feedstocks, but residue removal may reduce soil carbon (C). The inclusion of a cover crop in a corn bioenergy system could provide additional biomass, mitigating the negative effects of residue removal by adding to stable soil C pools. In a no-till continuous corn bioenergy system in the northern US Corn Belt, we used CO2 pulse labeling to trace plant C from ...
The effects of planting date, rye (Secale cereale cv. Wren Abruzzi) and wheat (Triticura aestivum cv. Coker 797), crop destruction, fallow, and soil temperature on managing Meloidogyne incognita race 1 were determined in a 2-year study. More M. incognita juveniles (J2) and egg-producing adults were found in roots of rye planted 1 October than in roots of rye planted 1 November and wheat planted...
Exposure of six wheat (Triticum aestivum L.) and one rye (Secale cereale L.) cultivar to 40% relative humidity for 24 hours induced the same degree of freezing tolerance in seedling epicotyls as did cold conditioning for 4 weeks at 2 degrees C.Frost hardiness varietal relationships were the same in desiccation-stressed and cold-hardened seedlings. Drought stress could, therefore, be used as a r...
The presence of legumin-like constituents within the globulin fractions of wheat (Triticum aestivum), rye (Secale cereale) and corn (maize, Zea mays) was demonstrated. Two-dimensional analysis of wheat globulins in the presence and absence of a reducing agent revealed the existence of reducible approximately 60 kDa polypeptides. Western-blot analysis with 125I-labelled antibodies raised against...
Quantification of soil carbon (C) cycling as influenced by management practices is needed for C sequestration and soil quality improvement. We evaluated the 10-yr effects of tillage, cropping system, and N source on crop residue and soil C fractions at 0- to 20-cm depth in Decatur silt loam (clayey, kaolinitic, thermic, Typic Paleudults) in northern Alabama, USA. Treatments were incomplete fact...
Antifreeze proteins are found in a wide range of overwintering plants where they inhibit the growth and recrystallization of ice that forms in intercellular spaces. Unlike antifreeze proteins found in fish and insects, plant antifreeze proteins have multiple, hydrophilic ice-binding domains. Surprisingly, antifreeze proteins from plants are homologous to pathogenesis-related proteins and also p...
Meiotic pairing preferences between identical and homologous but not identical chromosomes were analyzed in spontaneous tetraploid/diploid chimeras of three male grasshoppers (Eyprepocnemis plorans) whose chromosome pair 11 were heterozygous for C-banding pattern and in four induced tetraploid/diploid chimaeral rye plants (Secale cereale) heterozygous for telomeric heterochromatin C-bands in ch...
به منظور بررسی تاثیر پرتودهی بذر با اشعه گاما و پلی اتیلن گلیکول 6000 بر خصوصیات جوانه زنی و برخی پارامترهای فیزیولوژیک دو گونه secale montanum guss.و (l.) gaertn agropyron cristatum ، آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی انجام شد. بذرهای گونه های مورد تحقیق تحت تابش پرتو گاما با سطوح 0، 20، 40، 60، 100 و 150 گری و محلول پلی اتیلن گلیکول 6000 در سطوح 0، 4- و 8- بار در سه تکرار در ش...
