What is the structure of maize seed?
Endosperm: Maize grain consists of two unequal portions divided by a layer called epithelium. The bigger portion, the endosperm which is yellowish or whitish is the food storage tissue of the grain and is rich in starch. But its outermost layer contains only protein and is called aleurone layer.
What is Zea mays seed?
Maize (Zea mays) is the third most important cereal grain in the world, after wheat and rice, providing nutrients for humans and animals and serving as a basic raw material for production of starch, oil, protein, alcoholic beverages, food sweeteners, and fuel.
Is Zea mays c3 or C4?
C4
Maize (Zea mays) is an important crop and model with C4 photosynthetic machinery.
Is Zea mays a monocot or dicot?
monocot
Zea mays stem (c.s.): As a typical monocot stem, the corn stem does not have a very organized arrangement of tissues (especially compared to dicots).
What are the stages of germination in maize?

- Vegetative Stages: VE Emergence.
- Reproductive Stages: R1 Silk emergence.
- VE – Emergence.

Which NPK is best for maize?
The standard fertilizer recommendation for maize consists of 150 kg ha−1 NPK 14–23–14 and 50 kg ha−1 urea (Dugué 2010).
Which fertilizer is best for corn?
BEST OVERALL: The Old Farmer’s Almanac Organic Vegetable Fertilizer.
Is maize C3 or C4 plant?
C4 plants
C4 plants include many tropical grasses and are among the world’s most important crop species (maize and sugarcane).
Does maize follow C3 pathway?
Maize is a C4 plant. C4 plants use the C4 pathway or Hatch Slack pathway for carbon fixation during photosynthesis. Oxaloacetic acid (OAA), a 4 carbon compound is the first stable product of carbon fixation.
Why is Zea mays a monocot plant?
The Parts of a Corn Seedling (Zea mays, Monocotyledon) Monocotyledon: Monocotyledon embryos have one cotyledon that absorbs food. Monocots usually have narrow leaves with parallel veins, and flower parts in multiples of three.
Is Zea mays monoecious or dioecious?
monoecious plant
Maize (Zea mays) is a monoecious plant that produces imperfect (unisexual) male flowers, or florets, in the tassel and imperfect female florets in the ear.
What is maize life cycle?
The maize plant’s life cycle consists of two key developmental phases: the vegetative phase (V phase) and the reproductive phase (R phase).
What is the growth pattern of maize?
Corn Growth Stages
| Description of stages | |
|---|---|
| REPRODUCTIVE STAGES | |
| R1 | Silk – one or more silks extends outside of husk leaves |
| R2 | Blister – kernels resemble “blisters” with clear liquid |
| R3 | Milk – kernels filled with “milky” fluid |
What is germination explain all steps with diagram?
1) Imbibition: water fills the seed. 2) The water activates enzymes that begin the plant’s growth. 3) The seed grows a root to access water underground. 4) The seed grows shoots that grow towards the sun. 5) The shoots grow leaves and begin photmorphogenesis.
Is urea fertilizer good for maize?
Maize height and dry matter production were depressed with increasing salinity levels. The application of composted manure and urea fertilizer enhanced plant growth and nutrient uptake compared with the non-treated control. Maize growth was better under urea fertilizer than under composted manure.
Is Zea mays male or female?
Maize ( Zea mays) Maize (Zea mays). The flowers are unisexual, containing either stamens or ovary but not both. The long, crowded inflorescences bear flowers of only one sex. The male inflorescences are on terminal branches and the female inflorescences are lower down, on lateral branches.
Is Zea mays (maize) a lncRNA?
Zea mays (maize) is an important cereal crop, which was studied by various groups to identify their lncRNAs. Ma et al. (2008) found that Zm401, a possible lncRNA, is involved in the development of male gametophyte and anther development.
What is the scientific name of maize?
Zea mays, more commonly referred to as maize, is a member of the grass family Poaceae, or true grasses. Maize is thought to have originated 55–70 million years ago in what is now Central or South America and has since diversified into nearly 10 000 nondomestic relatives.
How do maize plants reproduce?
Zea mays is a member of the grass family and is one of the most diverse species of plants. Maize plants contain both male and female reproductive structures and reproduce by both cross-pollination and self-pollination.
