PLANT RESISTANCE Evaluation of Turfgrass Species and Cultivars for Potential Resistance to Twolined Spittlebug (Hemiptera: Cercopidae)
Potential resistance to the twolined spittlebug, Prosapia bicincta (Say), was evaluated among 56 turfgrass genotypes. Greenhouse, laboratory, and Þeld bioassays identiÞed differences in spittlebug survival and development, host preference and damage levels, and turfgrass tolerance to and ability to recover from pest induced injury. All centipede grasses demonstrated high levels of susceptibilit...

متن کاملSusceptibility of twolined spittlebug (Hemiptera: Cercopidae) life stages to entomophagous arthropods in turfgrass.
Prosapia bicincta (Say) (Hemiptera: Cercopidae), the twolined spittlebug, is an economic pest of turfgrass in the southeastern United States. No data concerning natural enemies of P. bicincta in turfgrass have been reported previously. We compared predation of spittlebug eggs, nymphs, and adults in the laboratory by potential generalist predators commonly found in turfgrass: bigeyed bugs Geocor...

این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Methylxanthines Accumulation in Ilex Species - Caffeine and Theobromine in Erva-Mate (Ilex paraguariensis) and Other Ilex Species
Ilex paraguariensis St.Hil. é uma espécie de importância econômica tendo em vista sua utilização na região meridional da América do Sul no preparo do chimarrão, uma bebida estimulante, preparada pela infusão de suas folhas e talos moídos. Este trabalho apresenta a análise de metilxantinas em folhas de I. paraguariensis e outras espécies de Ilex freqüentemente relatadas como adulterantes. A dete...
