APO1, a pivotal gene to regulate primary panicle branch, controlled the vascular bundle formation and could increase the harvest index and grain yield in rice (Terao et al. panicle in British English. A panicle is where "all inflorescences in which the spikelets are not borne on the main axis but occur on branches." (ˈpænɪkəl ) noun. Identification. panicle in Polish translation and definition "panicle", English-Polish Dictionary online. 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. Unlike some flower clusters, panicles tend to be loose and open instead of densely bunched. In inflorescence: Indeterminate inflorescence. The rice pictured above shows the rice plant on the left with a droopy panicle axis, and the rice plant on the rigth with a straight panicle axis. Hybrid rice accounts for about 50% of the total rice growing area in China (Normile, 2000). 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. 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. A minimum 20× hand lens is required to observe it on the inside of the leaf sheath. Many species of grasses such as oat, rice, and rye feature panicles. 92) Some observeable panicle characteristics are the panicle type, the secondary branching of the panicle, the panicle axis and the panicle exsertion. Panicle identification is the first step in panicle assessments such as by panicle counting, panicle length calculation, maturity degree assessment, and biomass prediction. PRM stands for Panicle Rice Mite. A panicle is a flower cluster that usually grows at the end of a stem or a shoot. Each productive tiller bears a terminal flowering head or panicle. Then their leaf stems start bulging, which conceals the developing panicle. Panicle exsertion, is the "exsertion of the panicle above the flag leaf sheath after anthesis." A panicle (see photograph) is a branched raceme in which the branches are themselves racemes (e.g., yuccas, Yucca ). 1. a compound raceme, occurring esp in grasses.
