causes it to create the best grain possible. Discussion: Vegetative: In this stage the plant germinates and gradually grows taller and leaves emerge at steady intervals. Germination: The root elongates through the seed coat and anchors into the soil. The primary leaf (coleoptile) also elongates and breaks through the seed coat. Early seedling growth: The first internode (mesocotyl) elongates and pushes the coleoptile through the soil. The seminal and secondary roots continue to develop‚

EFFECTS OF NITROGEN FIXING PEA PLANTS (Pisum sativum) ON GROWTH OF CORN (Zea mays) Introduction Interactions among plant species‚ particularly negative ones‚ have been a concern in agriculture (Levene 1926‚ Russell 1961). Novoa (1981) suggested that it would be advantageous to rotate certain crops by season‚ grow certain crops together‚ or avoid growing certain crops on the same land. Observations indicated that some crops require specific types of nutrients in contrast to other crop

39) Name the specific type of plant tissue or cell that performs the following functions: a) waterproofing the surface layer Endodermos b) rapidly dividing into new cells Mitosis c) transporting sugars throughout the plant Phloem 40)Maple syrup is produces from the sap moving in the xylem of maple trees in the early spring. How would taking too much sap in the spring harm the maple tree? That sap is an energy store to give it a strong start in spring. If you take too much

Growth Growth and development are the most fundamental characteristics of all living organisms. The physiological definition of growth is “An irreversible change in the organism‚ organ or cell is called growth”‚ which includes increase in mass weight or volume of living organism‚ it leads to development in plants. REGION OF GROWTH: Growth region is located at extreme apices of root‚ stem‚ leaf where we make out meristematic tissue. In addition to above‚ the region where intercalary and lateral

CROP PRODUCTION AND MANAGEMENT Types of Crops Soil Preparation Sowing Harvesting Fertilisers Insecticides All living organisms require food. Plants can make their food themselves. Animals including humans can not make their own food. The energy from food is utilized by organisms for carrying out their various body functions‚ such as digestion‚ respiration and excretion. We get our food from plants‚ or animals‚ or both. In order to provide food for a large population— regular

perennial herbaceous legume which can climb to 3-4 meters (Kantha and Erdman‚ 1985). As a leguminous plant‚ winged bean can be used in almost all parts of the plant. Fruit‚ leaves‚ flowers‚ bulbs and seed are edible and contain high protein and oil (Kotaru et al.‚ 1987; Dwiani et al.‚ 2014). The mature‚ dry seed is the most nutritious part of the winged bean. Their outstanding nutritive quality is based‚ above all‚ on their high protein content (30-42 percent) and their favorable amino acid composition

process of seed dispersal? As plants undergo the process of ripening‚ they produce their own ethylene. Ethylene is a simple gas that is produced when fruit ripens (Nemec‚ 2008). When the fruit is ripe it is responsible for seed dispersal by attracting animals to the fruit‚ who consume it and then the seeds are dispersed in their fecal matter or whatever remains of the uneaten portion of the fruit that is left on the ground will be absorbed into the soil (Mauseth‚ 2003). Another means of seed dispersal

INTRODUCTION Nepal is predominantly an agricultural country‚ people dependant on agriculture with raising household livestock. These livestock cannot be maintained on the fodder produced on arable land alone. In Nepal‚ agricultural crops are seldom grown specifically for fodder production except in some small areas. Because of increasing pressure of human population and also because of higher income from cereal and cash crops than from forage crops‚ more agriculture area cannot be set apart for
