    In vitro germination of Orobanche seeds in presence of tobacco root exudates and plant growth regulators

    BOSSOLOVA S.; SLAVOV S.; BATCHVAROVA R.
    Institute of Genetic Engineering, Kostinbrod, Bulgaria.
    Broomrape ( Orobanche ramosa L.) is an obligate root parasite which causes severe reduction of tobacco quality and yield. Seeds of the parasite germinate only in the presence of the host plant. An in vitro system for seed germination was...
