What is tillering ability?
Tillering ability is one of the yield-determining characters in the rice plant. The growth and development of tillers depend partially on environmental factors, especially on radia- tion, temperature, and nutritional conditions and partially on varietal characteristics (Hanada 1993).
What is rice tillering?
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.
How do you increase tillering in Paddy?
Fertilizing the crop during early vegetative growth promotes tillering leading to higher yield. Application at panicle initiation or early booting stage will help the plant produce more and heavier grains per panicle.
What is the function of tiller in rice?
Tillering allows the plant to expand and to produce more ears and therefore more grains per plant when interplant competition is low.
What is the tillering stage?
Tillering begins around 40 days after planting and can last up to 120 days. It is a physiological process of continuous underground branching of compact node joints of the primary shoot (Figure 2.8). Tillering gives the crop the necessary number of stalks required for a good production.
Why is a tiller important?
Tillers are an important component of the crop’s shoot system and through carbon capture and partitioning, contribute to seed yield. As a tiller grows and develops, additional tillers can form in the leaf axils of that tiller. All grasses produce tillers. Roots are also associated with each tiller.
What is tillering stage?
How many tillers does rice have?
The number of primary and secondary ramifications depends on species and variety. One single panicle can bear between 50 and 500 spikelets; however, in most cultivated varieties, their number reaches 150 to 350.
What are the 3 stages of plant growth?
The simplest way to describe plant growth is in 3 stages:
- Seed stage.
- Growth stage.
- Reproductive stage.
How do you promote tillering?
When plants produce seed they give no further growth but they sit there and reduce the emergence of new tillers. Therefore, the removal of seed-bearing stems and tall grass will encourage new tillering and set up swards for better quality and more productive grazing pastures into the autumn.
How do you encourage tillering?
Once the grass roots have strengthened and you can pull the grass without the roots pulling also you can graze the reseed. Short grazing intervals with young light cattle or sheep will encourage tillering while also reducing surface damage in the field.
What are the 4 stages of a plant?
The plant life cycle consists of four stages; seed, sprout, small plant, and adult plant. When the seed gets planted into the soil with water and sun, then it will start to grow into a small sprout.
When does a young Tiller die?
Those tillers initiating inflorescences in spring usually die before the end of summer. A young tiller depends on the parent shoot for photo-assimilates until it has developed several leaves and an adequate root system.
What is tillering in a tiller plant?
A tiller may become induced to flower if exposed to necessary growing conditions, otherwise it will remain vegetative. The process by which these new aerial shoots emerge is called tillering. In contrast to rhizome and stolon emergence, tillers develop upwards.
What grasses produce tillers from adventitious buds?
A single kernel of wheat may produce additional shoots (tillers) from adventitious buds in the crown zone. Corn (maize), a warm-season annual grass, produces suckers from basal nodes. With perennial grasses, some species produce tillers from adventitious buds in a manner similar to maize.
