Plant Regeneration of Commercial Cultivars of Tomato

In Vitro Plant Regeneration from Commercial Cultivars of Soybean

Soybean, a major legume crop, is the source of vegetable oil and protein. There is a need for transgenic approaches to breeding superior soybean varieties to meet future climate challenges. Efficient plant regeneration is a prerequisite for successful application of genetic transformation technology. Soybean cultivars are classified into different maturity groups based on photoperiod requiremen...

Tumor promoters in commercial indoor-plant cultivars of the Euphorbiaceae.

Certain decorative indoor-plant cultivars are derived from toxic wild plant species. Native members of the Euphorbiaceae (spurge) contain highly irritating and tumor-promoting diterpene esters. Plant breeders and gardeners are constantly searching for less toxic cultivars of the popular Euphorbiaceae indoor plants. In this investigation, 22 commercial cultivars of Euphorbiaceae indoor plants we...

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...

Comparisons of in vitro propagation of tomato cultivars

Somatic embryogenesis and plant regeneration of Vitis vinifera cultivars 'Macabeo' and 'Tempranillo'

Different experimental conditions have been compared to achieve a high efficiency in embryogenic calli initiation from 'Macabeo' and 'Tempranillo' anthers. Specifically, two stages of anther development were tested (corresponding to tetrad cells or uninucleate pollen), and direct culture of anthers was compared to culture after a cold treatment of inflorescences (4 °C during 48 h). In addition,...
