Sunflower seed germination and storability response to chemical desiccation

Hybrid sunflower seed yield, composition and deterioration after chemical desiccation

The impact of chemical desiccation on yield showed contrasting results depending on seedmoisture content at the time of application. Its effects on seed deterioration are still unknownand could be modified by seed composition. Objectives were to evaluate the impact of chemicaldesiccation on: i) hybrid sunflower seed yield and composition at harvest time, ii) seeddeterioration during long-term s...

Airborne allergy to sunflower seed.

BACKGROUND There is increasing evidence that bird fanciers may develop airborne allergies to unusual allergens. OBJECTIVE To detect the allergen source in a bird fancier with a history of asthma associated with bird cage cleaning activities and with contact with a Brazil parrot. METHODS SPT with a large series of both airborne and food allergens were carried out. IgE reactivity to allergens...

Response of Germination and Seedling Growth of Pepper cultivars to Seed Priming by Plant Growth Regulators

In order to study the germination and growth of pepper seeds, a factorial experiment based on a completely randomized design with three replications was conducted. The first factor was consisting of five cultivars of pepper (Marquiza, Cadia, California Wonder, California Wonder 310 and California Wonder 300) and the second factor was gibberellic acid with three levels (0 as control, 250 and 500...

Seed germination response of Haloxylon persicum (Chenopodiaceae) to different hydrothermal conditions and sand burial depths

Daily counts of germinated seeds of white saxaul (Haloxylon persicum) incubated at 35 different hydrothermal environments (10-25?C and 0 to -3 MPa) were carried out under controlled laboratory conditions. The seeds were then buried in sand at 4 different depths in well drained pots constantly moisturized for three weeks. In all these hydrothermal conditions, the courses of germination were comp...
