morphological characteristics of maize plant

Morphological Responses of Maize to Drought, Heat and Combined Stresses at Seedling Stage: Liliane Ngoune Tandzi, Graeme Bradley and Charles Mutengwa: Abstract: Background and Objective: Drought and heat stresses are major abiotic constraints causing limitations to plant growth worldwide and limited focus has been devoted to the combination of the two stresses. mays is a cultivated, annual grass that originated in Mexico. Facts. Maize (/ m eɪ z / MAYZ; Zea mays subsp. The leafy stalk of the plant produces pollen inflorescences and separate ovuliferous inflorescences called ears that yield kernels or seeds, which are fruits. Corn is often called maize, a Spanish corruption of one indigenous word for this plant. Leaves Morphology of Maize • Leaves are broad and a single leaf. Much of the interest and controversy surrounding the domestication of maize arises from the fact that these two plants have such strikingly different morphologies. Maize plant morphology of contrasting genetic backgrounds, i.e., semi-compact and compact hybrids, regarding density tolerance was tested. The effects of increased plant density on maize morphological development have been examined extensively at the canopy level including plant height, leaf area per plant and leaf area index [7, 12, 15, 16, 17, 18]. Plant Morphology of Maize • 1 to 4 meter tall • Approximately 30 leaves • A erect stalk- like structure • Is a meristem • Sheath surrounding the stalk • Expanded blade by blade joint or collar • Has nodes and internodes 5. It is now widely planted around the world for its grain. There has been little study on the effects of CRU on the morphological and physiological characteristics of maize roots under different soil moisture conditions. • The source of kernel loss, silking dynamics, and grain-filling characteristics of apical kernels were measured. Consequently, much attention has been directed to how the maize canopy responds to increased plant density [12, 14, 15]. Morphological characteristics. Five morphological fractions (leaf blade, leaf sheath, stem, husk and cob) of stover of five maize genotypes, namely waxy, conventional, fodder, sweet and high-oil maize, respectively, were used to test the effects of genotype and morphological fractions on chemical composition and in vitro fermentation characteristics. If you are planting very early or into a less than ideal seedbed or where insect pressure may be high (e.g. In the low Fe treatment, plant height and stem diameter of maize seedlings decreased significantly. On this page, I will describe the differences in plant and inflorescence morphology between maize and teosinte following the system that my lab has used in its QTL studies. The planting populations shown in the Pioneer ® brand maize for grain hybrid trait characteristics chart (on page 36) assume good seed establishment conditions. Zea mays ssp. Greater decreases were observed when plants were stressed for a longer period . mays, from Spanish: maíz after Taino: mahiz), also known as corn (American English), is a cereal grain first domesticated by indigenous peoples in southern Mexico about 10,000 years ago. A total of 10 maize cultivars with a wide range of growth stages and a wide range of lodging resistance were planted in 2018. Based on the results for 2018, four widely planted maize cultivars were planted in 2019 (Table 2).In both 2018 and 2019, the sowing date was 13 June and the planting density was 7.5 × 10 4 plants ha −1.Each plot contained 10 rows, each with a length of 10 m … Originated in Mexico dynamics, and grain-filling characteristics of maize seedlings decreased.... 12, 14, 15 ] decreased significantly decreased significantly total of 10 cultivars...
