Plant height varies by variety and environmental conditions, ranging from approximately 0.4 meter (m) to more than 5 m in some floating rice. Such root system is built up with seminal and nodal roots with numerous lateral roots. Biosystematists recently divided the genus Oryza into several sections and placed O. sativa under series Sativa in section Sativae. For example, Fig. Lawas,a Cherryl Quinones,a Rajeev N.

We can say that half of Rice grain is the second food in the world after wheat, and the first in Asia. So the physical look. The staging of rice plant reproductive development is needed in experiments to define phase transitions of seed biology. The botanist would observe that the inflorescence is a terminal panicle … Aside from improving lodging resistance, a thick culm may also act as a carbohydrate store for high yield in rice (Hirose et al., 2006). 2.3 Habitat and Morphology of Rice ... a rice plant showed significant (P<0.05) differences in the wild/weedy populations from the cultivars while the two cultivars did not show any significant (P>0.05) difference in their morphological characteristics and phenology. The rice grain, commonly called a seed, consists of the true fruit or brown rice (caryopsis) and the hull, which encloses the brown rice.

In direct-seeded rice fields with a normal plant population (10 to 20 plants per square foot), rice plants generally produce two to five panicle-bearing tillers per plant compared to 10 to 30 tillers per plant in transplanted rice where more space is available between plants. The Root In Dicotyledons, elongation of radicle forms the primary roots which bears lateral roots of the several orders called secondary roots, tertiary roots etc. In the present study, we attempted to test this hypothesis using two rice cultivars representing upland and lowland ecotypes grown in specially designed split and stratified soil cultures with a low-phosphorus red soil. Morphology Characters of Plants: Morphological characters of the plants have provided the foundation and framework for taxonomy and they have been used extensively in the preparation of classification systems, diagnostic keys, etc. Tillering in rice (Oryza sativa L.) is an important agronomic trait for grain production, and also a model system for the study of branching in monocotyledonous plants. 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). Monog.

At maturity the rice plant has a main stem and a number of tillers. Roughly one-half of the world population, including virtually all of East and Southeast Asia, is wholly dependent upon rice as a staple food; 95 percent of the world’s rice crop is eaten by humans.

Phenotype of panicle morphology both parents used as plant crossing materials. Rice is a model plant of monocots and an important crop that feeds more than half of the population around the globe. Introduction of the cloned OSH1 gene into rice resulted in altered leaf morphology, which was similar to that of the maize morphological mutant Knotted-1 (Kn1), indicating that OSH1 is a rice gene homologous to the maize Kn1 gene. Grains from wild rice species exhibited a variety of colours that have potential aesthetic and nutritional value. Plant height varies by variety and environmental conditions, ranging from approximately 0.4 meter (m) to more than 5 m in some floating rice. Root is defined as the descending part of the plant axis. Plant anatomy describes the structure and organisation of the cells, tissues and organs of plants, whereas plant morphology describes the external form and structure of plants.

Red rice plants are difficult to differentiate from rice culti-vars at the seedling stage; however, at tillering, flowering, or maturity stages, red rice plants are recognizable by the following characteristics: a) hispid, light-green leaves, b) profuse tillering, c) longer and more slender panicles, and d) heavy shattering of grains (7, 8, 14, 15).
