Growth Stages Of Rice Plants

The Growth Stages of Rice Plants

The cultivation of rice takes place with stages 0-9. It grows much like the stages of grass. It can take 3-6 months depending upon the type of rice and where it is being grown.
The rice plant has three different phases that it undergoes during its growth, vegetative, reproductive, and ripening. Each of the phases are subdivided into stages. The vegetative phase is characterized by active tillering gradual increase in plant height and leaf emergence at regular intervals. The stages under the vegetative phase begin with Stage 0-germination to emergence. In this stage the seeds are usually pregerminated for about 24 hours. The seed is then planted and after the second and third day the first leaf will break through the coleoptile. At the end of Stage 0 the primary leaf has emerged still curled. The next stage, the seedling stage, seminal roots and up to five leaves develop. The leaves develop at a rate of one every three to four days. Secondary roots that form the fibrous root system begin to replace the seminal roots. At the appearance of the first tiller, stage 2, the tillering stage begins. Tillers emerge from axilliary buds and displace the leaf as they grow. Peimary tillers give rise to secondary tillers and eventually tertiary tillers as the plant grows longer and larger. Tillers continue to grow as the plant enters stage three, stm elongation. Ground cover and canopy formation advance by the plants. Growth duration is directly related to stem elongation. Plants with a longer growth duration have a more visible stem elongation stage whereas the short duration plants tend to have the tillering, stem elongation and panicle initiation occur almost simultaneously. Stage four, the panicle initiation, brings us into the reproductive phase. The panicle primordium will become visible. Three leaves will emerge before
