Pericarp, seed coat anatomy and seed morphology of Calycanthaceae

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...

Investigations into seed dormancy in Grevillea linearifolia, G. buxifolia and G. sericea: anatomy and histochemistry of the seed coat.

BACKGROUND AND AIMS Seeds of east Australian Grevillea species generally recruit post-fire; previous work showed that the seed coat was the controller of dormancy in Grevillea linearifolia. Former studies on seed development in Grevillea have concentrated on embryology, with little information that would allow testing of hypotheses about the breaking of dormancy by fire-related cues. Our aim wa...

Organic Corn Seed Coat Treatments

Introduction Organic seed treatments have been limited in organic production, until recently. Agricoat Natural IITM, is reported to be “an organic liquid biological seed treatment applied as a seed film coating and formulated with beneficial microbes, macro and micro nutrients, amino acids, organic acids, enzymes, proteins, vitamins, and minerals.” Natural IITM also is applied to “promote root ...

Wood Anatomy of Calycanthaceae

The Maize Seed Anatomy of the Mature Maize Seed

The pericarp consist in the transformed wall of the ovary that covers the seed and acts as a protection for the embryo and endosperm. It takes the place of the seed coats or integuments in the ordinary seeds, which in maize are reduced to unnoticeable remnants in the mature kernel. A thin, suberized nucellar membrane derived from the outer epidermal wall of the nucellus persists as a continuous...
