A deep learning-based method was developed for rice productive tiller detection. 2003). By continuing you agree to the use of cookies. Cultivated rice is generally considered a semiaquatic annual grass, although in the tropics it can survive as a perennial, producing new tillers from nodes after harvest (ratooning). However, the mechanisms underlying transcriptional regulation of HSFA2D remain unknown. Morphology and Development of the Rice Plant . The web app had an accuracy of over 99% compared with manual counting results. The number of productive tillers per plant is one of the important agronomic traits associated with the grain yield of rice crop. Plant height varies by variety and environmental conditions, ranging from approximately 0.4 m to over 5 m in some floating rices. One seedling can produce a number of tillers (depends of stand density - see Figure 6 later in chapter) and ultimately panicles; however 60 to 70 pan- icles/ft2are about optimum for good yields with calrose type varieties (Table 2). ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. The number of panicles in a yield component depends largely on the number of tillers (p.222. which is distinct from the lateral branching of dicotyledonous plants. tillers plant-1, number of productive tillers plant-, panicle length, straw yield and harvest index. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. 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. number of grains per panicle (59.35%), number of productive tillers (55.38%), grain weight per hill (33.98%) and the characters that showed the highest heritability in the argon ion treatment were grain weight per hill (96.57%), panicle density (72.38%), number of productive tillers (67.43%) and number of grain per panicle (panicle) 65.32%). The present They are involved in vegetative propagation and, in some cases, also seed production. Rice branching has attracted much attention because of its importance in food production. At maturity the rice plant has a main stem and a number of tillers. At genotypic ... is a great challenge to meet the present demand of rice production to sustain the population of our country. In this study, a method for automatically detecting and counting productive tillers of rice crop was proposed based on deep learning convolutional neural network (CNN). Deep learning-based automatic detection of productive tillers in rice. https://doi.org/10.1016/j.compag.2020.105703. Vol. Ectopic expression of some of these GA2ox6 mutants moderately lowered GA levels and reprogrammed transcriptional networks, leading to reduced plant height, more productive tillers, expanded root system, higher WUE and photosynthesis rate, and elevated abiotic and biotic stress tolerance in transgenic rice. Results showed that the selected CNN model had a high precision and a fast detection rate. Furthermore, the performance of the Web app was not affected by the environmental conditions, such as illumination condition (cloudy or sunny) and water reflection in paddy fields. Ganito itsura ng 70 productive tillers na inbred RC300 variety na produce using Insta Organicfarm Enhanced Microbial Inoculant. Rice is a major source of food, particularly for the growing Asian population; hence, the utilization of genes for enhancing its yield potential is important for ensuring food security. The number of productive tillers per plant is one of the important agronomic traits associated with the grain yield of rice crop. Gramineous plants have a special type of side shoot referred to as a tiller. © 2020 Elsevier B.V. All rights reserved. However, only the early ones formed from the unelongated internodes outgrow as tillers, whereas later ones formed from the upper internodes remain dormant.
