panicle initiation stage of rice

Veröffentlicht von am

Panicle initiation is the second best time to apply nitrogen to a rice crop with pre-permanent water being the most efficient. ... growth.The rice plant is susceptible to salinity especially at the seedling stage and during the panicle development stage from panicle initiation to booting. Ground-based hyperspectral imaging was applied to rice plants at the panicle initiation stage to estimate nitrogen content. 2 B and C), then it started to Plant Nutr.. 48 (2), 151-158, 2002 Water Uptake under Water Stress at Panicle Initiation Stage in Upland Rice as Affected by Previous Soil Water Regimes Kanako Okada!, Motohiko Kondo2, Ho Ando*, and Ken-ichi Kakuda* International Rice Research Institute, P.O. Panicle Initiation (PI) – is the time when the panicle premordia initiate the production of a panicle in the uppermost node of the culm. Browse Titles Subjects SUBSCRIPTIONS AUTHORS LIBRARIANS ABOUT FAQ Keywords Rice Salt stress Panicle initiation Microarray Introduction Rice is one of the most economically important crops of the world. Spikelet anthesis (or flowering) begins with panicle exertion (heading), or on the following day. Most varieties take 50–55 days from panicle initiation to harvest. Rice panicle mor-phology is largely determined by the timing of identity transition among the different types of meristems (SI Appendix,Fig.S1). ORIGINAL ARTICLE Open Access The Initiation of Inferior Grain Filling is Affected by Sugar Translocation Efficiency in Large Panicle Rice Lin Chen1,2,3,4*, Yao Deng1,2, Honglei Zhu1,2, Yuxiang Hu1,2, Zhengrong Jiang1,2, She Tang1,2,3, Shaohua Wang1,2,3 and Yanfeng Ding1,2,3,4* Abstract Brown rice consists mainly of the embryo and endosperm. But what ex-actly is PI and why is it so impor-tant? SeMet was also the main Se-species found in different subcellular parts at the panicle initiation stage. Urea fertilizer was broadcasted at three stages (50% as a top dress before the maximum tillering stage, 25% as a top dress at the panicle initiation stage, and 25% at the flowering stage). The main crops were subjected to drought by draining the field when the first genotypes entered panicle initiation stage at 59, 51, and 53 d after final sowing in 2017DS, 2017WS, and 2018DS, respectively. Among weed management Direct seeding of rice in the Indo nutrient in determining the level of cro productivity of upland rice (Angiras, 2002) ... competition to the crop in early stage and cause heavy reduction in rice yield. Photosynthesis is a major process for determining plant growth and development. Seeds The rice grain, commonly called a seed, consists of the true fruit or brown rice (caryopsis) and the hull, which encloses the brown rice. Rice yields can be reduced by up to 50% when grown under moderate (6 dS m–1) salinity levels (Zeng et al. It is some­ times referred to as the green ring stage in rice (Figure 1-5). KEGG pathway incident of panicle initiation and grain filling stage in Rajalaxmi hybrid. Heat events will occur at all stages during the reproductive phase of rice as a result of global warming. 2020 , 21 , x FOR PEER REVIEW 6 of 16 Tillering means that several stems develop on one plant (Figure 22). In rice, panicle and flower development is under environmental and genetic control; development of a mature flower from the stage of panicle initiation occurs in a step-wise manner over a four to five week period (Hoshikawa 1989). RNA-Seq technology was used to analyze the transcriptome of two rice hybrids, Ajay (based on wild-abortive (WA)-cytoplasm) and Rajalaxmi (based on Kalinga-cytoplasm), and their respective parents at the panicle initiation (PI) and grain filling (GF) stages. RNA-Seq technology was used to analyze the transcriptome of two rice hybrids, Ajay (based on wild-abortive (WA)-cytoplasm) and Rajalaxmi (based on Kalinga-cytoplasm), and their respective parents at the panicle initiation (PI) and grain filling (GF) stages. Furthermore, some rice mutants affecting panicle formation or grain number have been re-ported. accompanied with panicle branch initiation ... analyses of the rice genome and cDNAs have rapidly pro-gressed (2, 3). Y-Leaf SeMet was also the main Se-species found in different subcellular parts at the panicle initiation stage. Of all the yield com-ponents, the number of panicles per unit area is the most easily ... tillering stage and triggers panicle initiation or reproduc-tive growth. Then the tip of the developing panicle emerges from the stem and continues to grow. The temperature plays important roles in plant photosynthesis. The Soil Plant Analysis Development (SPAD) value was used as a reference data that indirectly reflects the nitrogen status in rice. panicle initiation stage, flowering stage, milk stage and hard dough stage from 3 0 randomly selected plants/plot. J. Mol. The acquired images were divided into two … Se speciation assays showed that SeCys and SeMet were the two main forms found in rice, of which SeMet accounted for 65.5%–100% in the ears and leaves, while SeCys accounted for 61.4%–75.6% in brown rice.
