What is panicle length?
Panicle length is one aspect of panicle architecture and is usually measured as a yield-related trait. Panicle length, together with spikelet number and density, seed setting rate and grain plumpness, determines the grain number per panicle; hence, yield increases in rice.
How do you measure rice panicles?
Rice panicle length, defined as the length from the panicle neck to the apex (Xiao et al., 1998), is generally measured at the maturity stage. The panicle neck, which has a cyclic structure, is treated as the dividing point between the stem and the panicle.
What is rice panicle?
Summary. 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.
What does rice Yield mean?
Yield components refer to the structures of the rice plant that directly translate into yield. These are: the number of panicles per given area, the number of spikelets (potential) grains per panicle, the percent of filled grains per panicle, and the weight of each grain.
What is the meaning of the word panicle?
Panicle definition The definition of a panicle is a cluster of flowers on a branch. A lilac is an example of a panicle. noun. A loosely branched inflorescence, especially a branching raceme. noun.
How do you increase rice yield?
The three factors that could contribute to increased rice productivity are: (a) developing new rice varieties including hybrids with higher yield potential; (b) minimizing the yield gap between what is currently harvested by farmers and the achievable highest on-farm yield of varieties they grow; and (c) reducing the …
What is grain yield of rice?
Rice grain yield is determined by panicle number, spikelet number per panicle, grain weight and grain filling (or the percentage of ripened grains per total grains).
What is panicle in crop?
A panicle is a much-branched inflorescence. Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). The branches of a panicle are often racemes. A panicle may have determinate or indeterminate growth.
What is difference between Spike and panicle?
A panicle is a branched raceme in which each branch has more than one flower, as in the astilbe (Astilbe). Panicles of astilbe (Astilbe). A spike is a raceme, but the flowers develop directly from the stem and are not borne on pedicels, as in barley (Hordeum).
What is a good yield for rice?
The average yield of rice (seeds) per hectare is 3 – 6 tons. In some countries like Australia and in Egypt, the yield can increase to an amazing 10 – 12 tons or more per hectare. (1 ton = 1000 kg = 2200 lbs.
What is panicle example?
Panicle definition A branched indeterminate inflorescence in which the branches are racemes, so that each flower has its own stalk (called a pedicel) attached to the branch. Oats and sorghum have panicles. 2. The definition of a panicle is a cluster of flowers on a branch. A lilac is an example of a panicle.
What is panicle in mango?
To briefly describe the mango panicle, it consists of a primary axis bearing many secondary axes (primary branches), each of which bears tertiary axes (secondary branches).
Is NPK fertilizer good for rice?
In terms of output of rice, fertilizer N-P-K (20 10 10) proves better at dose 200 kg than fertilizer N-P-K (23 10 05) at the same dose. For good growth and yield the use of appropriate doses of fertilisers will significantly improve the yield of rice.
What do you mean by panicle?
How can I increase rice yield?
Is panicle length related to grain yield in rice?
Panicle length (PL) is an important trait for improving panicle architecture and grain yield in rice (Oryza sativa L.). Three populations were used to identify QTLs and candidate genes associated with PL. Four QTLs for PL were detected on chromosomes 4, 6, and 9 through linkage mapping in the recomb …
