Probing Behavior of Empoasca vitis (Homoptera: Cicadellidae) on Resistant and Susceptible Cultivars of Tea Plants

Probing Behavior of Empoasca vitis (Homoptera: Cicadellidae) on Resistant and Susceptible Cultivars of Tea Plants

Feeding activities of the tea green leafhopper, Empoasca vitis (Gothe) (Homoptera: Cicadellidae), on resistant and susceptible cultivars of tea plants (Camellia sinensis L.) were recorded and analyzed using the direct current electrical penetration graph (EPG) system. Six distinct EPG waveforms characterizing the feeding behavior of the tea green leafhopper, categorized as waveforms A, C, E, S,...

effect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars

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...

Growth and Energy Demand of Meloidogyne incognita on Susceptible and Resistant Vitis vinifera Cultivars.

Food (energy) consumption rates ofMeloidogyne incognita were calculated on Vitis vinifera cv. French Colombard (highly susceptible) and cv. Thompson Seedless (moderately resistant). One-month-old grape seedlings in styrofoam cups were inoculated with 2,000 or 8,000 M. incognita second-stage juveniles (J2) and maintained at 17.5 degree days (DD - base 10 C)/day until maximum adult female growth ...

Growth of poccinia hordei on leaf surface of susceptible and resistant barley cultivars

Physiological Response of Resistant and Susceptible Vitis vinifera Cultivars to Meloidogyne incognita

The effect of Meloidogyne incognita on growth, general physiological response, and the concentrat ion of reducing and nonreducing sugars at the nematode feeding sites of French Colombard (susceptible) and Thompson Seedless (moderately resistant) Vitis vinifera cultivars was studied up to 2,100 degree-days (DD-base 10 C). Nematode stress dosage, measured as the product of cumulative number of ju...
