Rice tiller is a specialized grain-bearing branch that is formed on the unelongated basal internode and grows independently of the mother stem (culm) by means of its own adventitious roots. Rice tillering occurs in a two-stage process: the formation of an axillary bud at each leaf axil and its subsequent outgrowth.
2 Tiller Production. The tillering ability of rice plants is seen in the number of phyllochrons of growth that they complete before entering their reproductive stage (Nemoto et al., 1995; Stoop et al., 2002).
Beside above, what is tillering in agriculture? A tiller is a stem produced by grass plants, and refers to all shoots that grow after the initial parent shoot grows from a seed. Tillers are segmented, each segment possessing its own two-part leaf. Tillering rates are heavily influenced by soil water status.
Regarding this, what is Rice tillering stage?
Tillering Stage. This stage begins with the emergence of the first tiller and ends at Panicle Initiation. This period lasts from about 18 days after sowing to. about 45 days after sowing. It is the period of rapid.
What are the parts of rice?
Grain or paddy: The rice grain is composed of three main parts: The rice envelope made of glumes (large portions above the pedicels that link the spikelets to the secondary ramifications) and the two husks called palea (upper husk with three /veins) and lemma (lower husk with 5 veins).
What is the life cycle of rice?
The rice plant usually takes 3-6 months from germination to maturity, depending on the variety and the environment. Agronomically the growth cycle can be divided into 3 growth stages: vegetative, reproductive, and ripening. Vegetative stage: tillering, gradual increase in plant height and leaf emergence.
How does Rice reproduce?
During reproduction, the stigma catches pollen from the stamens and conducts it down to the ovary, where it comes into contact with the ovule and fertilization occurs. The grain is the seed of the rice plant, a fertilized and ripened ovule containing a live embryo capable of germinating to produce a new plant.
What is panicle initiation in rice?
Panicle Initiation (PI) is the start of the reproductive phase of rice development. It is when the actual panicle or head begins to form in the base of the shoots or stems, just above the soil surface.
Where is Rice on the plant?
Rice is the seed of the grass species Oryza sativa (Asian rice) or Oryza glaberrima (African rice). As a cereal grain, it is the most widely consumed staple food for a large part of the world’s human population, especially in Asia.
What type of root does Rice have?
Rice form a fibrous root system consisting of seminal, nodal and lateral roots.
Is Rice a grain?
It’s not just a grain, it’s one of the grains. Yes, rice, along with wheat, oats, cornmeal, and barley make up the entire grain food group. But that being said, rice is a lot different from most other cereal grains. Whole grains are made up of the entire kernel of grain, including germ, bran, and endosperm.
Is rice flowering plant?
Parts of the rice plant Cultivated rice is generally considered a semiaquatic annual grass, although in the tropics it can survive as a perennial, producing new tillers from nodes after harvest (ratooning). Each productive tiller bears a terminal flowering head or panicle.
Which part of the rice plant is sugar manufactured?
The bottom portion of the leaf, called the sheath, clings to the stem. The sheath protects the undeveloped buds between the leaf and the stem. The primary function of leaves is to produce food for the plant by turning sunlight, water and carbon dioxide in to simple sugars that the plant can use.
How long does it take to produce rice?
four to five months
How many days does it take to grow rice?
It may vary a little depending on the growing conditions especially water availability and solar radiation. Normally short duration varieties take 100−120 days, medium duration 120−140 days, and long duration 160 days plus. Most varieties take 60−65 days from panicle initiation to harvest.
Which is the best fertilizer for paddy?
Urea should be the fertilizer of choice for the cultivation of paddy rice.
How much water does it take to grow rice?
Rice is a water gulping crop and on an average of about 2,500 litres of water need to be supplied (by rainfall or irrigation) to the rice field to produce 1 kg of rough rice (Bouman, 2009) .
How do you increase rice yield?
Several approaches for increasing the yield potential of rice are being used, such as population improvement, ideotype breeding, heterosis breeding, wide hybridization, genetic engineering, and molecular breeding.
What are the three phases of growth?
The three phases of cell growth are cell division, cell enlargement and cell differentiation. The first two stages increase the size of the plant cell while the 3rd stage brings maturity to the cells.
