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...

متن کاملFast-Flowering Mini-Maize: Seed to Seed in 60 Days.
Two lines of Zea mays were developed as a short-generation model for maize. The Fast-Flowering Mini-Maize (FFMM) lines A and B are robust inbred lines with a significantly shorter generation time, much smaller stature, and better greenhouse adaptation than traditional maize varieties. Five generations a year are typical. FFMM is the result of a modified double-cross hybrid between four fast-flo...
متن کاملExploring seed to seed effects for understanding invasive species success
Comparative approaches between native and invasive species germination are useful for understanding invasion success. We studied the role of invasive–native neighboring seeds on germination and early growth of different grasses. We focused on the non-native species Eragrostis plana Ness, the most invasive plant in southern Brazilian grasslands. A germination experiment was performed with three ...
متن کاملMaternal Gametophyte Effects on Seed Development in Maize
Flowering plants, like placental mammals, have an extensive maternal contribution toward progeny development. Plants are distinguished from animals by a genetically active haploid phase of growth and development between meiosis and fertilization, called the gametophyte. Flowering plants are further distinguished by the process of double fertilization that produces sister progeny, the endosperm ...
