Aug 31, 2024 · Rice (Oryza sativa) is a Gramineae plant very famous for its seeds. Rice grain is the second food in the world after wheat , and the first in Asia . Nations so inhabited as China or India essentially base their feeding on this food.

Rice form a fibrous root system consisting of seminal, nodal and lateral roots. As the rice grain germinates, the radical pierces its way out through the coleorhizae and the enveloping glume and forms the seminal root.

Nov 25, 2021 · The vegetative phase of development in rice begins with germination followed by seedling growth when physiological dormancy is broken and the seed absorbs water. In germination, the radicle ruptures the seed coat first.

Rice requires warm, moist conditions for growth and is grown world-wide in tropical and warm temperate habitats. As is the case in all ‘cereal grains’ the ‘cereal’— the portion eaten — is a one-seeded fruit with the cells of a very thin fruit fused to those of the seed coat.

The rice plant may be characterized as an an- nual grass, with round, hollow, jointed culms, rather flat, sessile leaf blades, and a terminal panicle, Under favorable conditions, the plant may grow more than one year. As other taxa in the tribe Oryzeae, rice is adapted to an aquatic habitat.

Rice seed: rice grain, commonly called a seed, consists of the true fruit or brown rice (caryopsis) and the hull, which encloses the brown rice. Brown rice consists mainly of the embryo and endosperm.

Botany of Rice Plant Abstract Cultivated rice Oryza sativa L. is a semi-aquatic annual grass belonging to the family Poaceae of class Monocotyledonae of angiosperm plants.

Rice is a bisexual, self-pollinated crop having a growth period of 3-6 months. Plant height varies from 0.4 to more than 5 meters in the case of floating rice. There are three distinct growth phases; they are vegetative, reproductive, and ripening. The vegetative phase covers a period from germination to panicle initiation.
