The first sign that the rice plant is getting ready to enter its reproductive phase is a bulging of the leaf stem that conceals the developing panicle, called the ‘booting’ stage. Panicle identification is the first step in panicle assessments such as by panicle counting, panicle length calculation, maturity degree assessment, and biomass prediction. Cyptocephala alvarengai required 33.2 d from first instar to adult, very close to that observed in other bugs of rice panicle. 2. any branched inflorescence. It is when the actual panicle or head begins to form in the base of the shoots or stems, just above the soil surface. The analysis of the panicle axis is a visual evaluation of the panicle at maturity. Jasmine rice panicle extract was shown to have a high content of p-coumaric, ferulic and caffeic acids, and was not cytotoxic to the cell lines used in this study.Cells treated with extract suppressed melanogenesis via tyrosinase and TRP-2 inhibitory effects, which protect the cell from oxidative stress at doses of 0.1 mg/ml or lower.

The tillering capacity of rice plants help compensate for poor stands, but there is a price to be paid. When rice paddies grow from their seeds to mature plants, they go through a variety of transformations. Each productive tiller bears a terminal flowering head or panicle. 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. The forming of the panicle marks the end of the tillering or vegetative phase and the beginning of the reproductive phase. panicle translation in English-Swedish dictionary. late′ (pə-nĭk′yə-lĭt, -lāt′) adj. Figure 2-9) is the time when the panicle pre couple of days. Germination in rice occurs when the first shoots and roots start to emerge from the seed and the rice plant begins to grow.To germinate, rice seeds need to absorb a certain amount of water and be exposed to a temperature range of 10–40 °C. When a lot of tillers per plant are produced, panicle maturity will be uneven, compromising grain quality at harvest. A loosely branched inflorescence, especially a branching raceme. (a), (c), (e), and (g) show the original RGB images of a rice plant. This is a critical stage during rice effect on rice plant development. Panicle identification is the first step in panicle assessments such as by panicle counting, panicle length calculation, maturity degree assessment, and biomass prediction. 2009).

Panicle Initiation (PI) is the start of the reproductive phase of rice development. The mites are clear to straw-colored and are approximately 250 µm in length. Rice (Oryza sativa) is one of the most important food crops in the world.Numerous quantitative trait loci or genes controlling panicle architecture have been identified to increase grain yield. At this point, the panicle is not visible to the naked eye. A minimum 20× hand lens is required to observe it on the inside of the leaf sheath. Hybrid rice accounts for about 50% of the total rice growing area in China (Normile, 2000). Hybrid rice accounts for about 50% of the total rice growing area in China (Normile, 2000). A panicle is where "all inflorescences in which the spikelets are not borne on the main axis but occur on branches." When stands are very dense, tillers may not even develop or may die before they can produce a panicle due to shading. 1. a compound raceme, occurring esp in grasses. PI is defined as when 3 out of 10 main shoots have a panicle 1 to 2 mm long, above the airspace or internode. Type: noun; Copy to clipboard; Details / edit; plwiktionary-2017.

The male has elongated rear legs containing a pair of elongated spines. At maturity the rice plant has a main stem and a number of tillers. Some authors distinguish it from a compound spike inflorescence, by requiring that the flowers (and fruit) be pedicellate (having a single stem per flower). However, almost all the cytoplasmic male sterile lines as the female (A line) of hybrid rice have a natural deficiency of ‘panicle enclosure’ in which panicles are partially or fully enclosed in the flag leaf sheath (Yin et al., 2007).
