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. However, the mechanisms underlying transcriptional regulation of HSFA2D remain unknown. However, not every tiller provides high productivity; instead, a sufficient N source leads to the production of tillers with low yield potential. Plant height varies by variety and environmental conditions, ranging from approximately 0.4 m to over 5 m in some floating rices. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Enhanced OsNLP4‐OsNiR cascade confers nitrogen use efficiency by promoting tiller number in rice. A tiller number is the key determinant of rice plant architecture and panicle number and consequently controls grain yield. After panicle initiation, tillers may continue to emerge from preexisting tillers, filling out the space among plants. By continuing you agree to the use of cookies. Rice tillers are specialized branches arising from axillary buds, usually at basal nodes of the primary stem (culm) and each bears a panicle. Congratulations Instalink Mindanao!!! Through applying the Web app to 200 in-field images with 5 to 30 tillers per image, the number of productive tillers detected agreed well with manual counting data, regardless of rice variety or type of mobile phone used for image taking. We use cookies to help provide and enhance our service and tailor content and ads. A deep learning-based method was developed for rice productive tiller detection. The web app had an accuracy of over 99% compared with manual counting results. Basic requirements Rice is mainly grown in warmer regions as the plants will not grow at temperatures below 10°C. Tillers are segmented, each segment possessing its own two-part leaf. We are committed to do several research and innovations to boost rice yields, sustain the growing population, create prosperity for the farmers, and secure rice sufficiency not only in the Philippines, but also in countries like Bangladesh, Indonesia and Myanmar among others. The method was implemented in a high-throughput and low-cost web app. Each productive tiller bears a At genotypic ... is a great challenge to meet the present demand of rice production to sustain the population of our country. At maturity the rice plant has a main stem and a number of tillers. The coefficients of determination between the Web app detection and manual counting of tillers were over 0.97 in all cases. The objective of this study was to characterize the contribution of cultivar tillering ability to dry matter accumulation, yield components, and grain yield. Tertiary tiller production continues up to the maximum tillering stage . Copyright © 2020 Elsevier B.V. or its licensors or contributors. The CNN model was trained using large amounts of in-field images taken by mobile phones from various varieties of rice crops under various environmental conditions. Deep learning-based automatic detection of productive tillers in rice. Botany of Paddy Rice is one of the most important food crops in the world and it is the staple food for over 2.7 billion people. • SRI changes the structure of rice plants -- the density and number of their roots and tillers -- by changing the practices used to manage rice plants, the soil they grow in, and the water they receive through irrigation, so that the plants can become more productive For rice plants to be more productive, they need to have: • More tillers per plant, • More fertile tillers (panicles) which form from the tillers that a plant … Vol. Branching comprises a protective mechanism for higher plants, by assisting with reducing the impacts of injury, and facilitating adaptation to the environment (Horvath et al. 2003). Ganito itsura ng 70 productive tillers na inbred RC300 variety na produce using Insta Organicfarm Enhanced Microbial Inoculant. However, only the early ones formed from the unelongated internodes outgrow as tillers, whereas later ones formed from the upper internodes remain dormant. When planted into flooded soil, the shoot is the first to emerge from the seed, with the roots developing when the first shoot has reached the ai… https://doi.org/10.1016/j.compag.2020.105703. 1 a). For … Rice branching has attracted much attention because of its importance in food production. A recent study revealed that HEAT STRESS TRANSCRIPTION FACTOR2D ( HSFA2D ) acts upstream of LAZY1 ( LA1 ) to regulate tiller angle establishment in rice ( Oryza sativa ). However, manual counting of productive tillers is time-consuming, laborious and error-prone. © 2020 Elsevier B.V. All rights reserved. The present Some of the later-formed tiller buds die or remain dormant. 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. Thus, it is necessary to optimize the tiller number to After … Each productive tiller bears a terminal flowering head or panicle. The performance of the web app was unaffected by the environmental conditions. 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). A deep learning-based method was developed for rice productive tiller detection. https://doi.org/10.1016/j.compag.2020.105703. Overall, compared to the manual counting, the accuracy of the Web app was over 99%. Secondary tillers bear a third group of tillers; the tertiary tillers. Through applying the Web app to 200 in-field images with 5 to 30 tillers per image, the number of productive tillers detected agreed well with manual counting data, regardless of rice variety or type of mobile phone used for image taking. 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). Morphology and Development of the Rice Plant . 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. Axillary buds produce tillers during the vegetative stage. The number of productive tillers per plant is one of the important agronomic traits associated with the grain yield of rice crop. A Web app, integrating the trained CNN model and a Django server, was designed for fast and high-throughput detection of productive tillers. However, manual counting of productive tillers is time-consuming, laborious and error-prone. They are involved in vegetative propagation and, in some cases, also seed production. Productive Tillers: 12 to 28 / plant. This step was to expose the transversal cross-sections of the tiller stems. At maturity the rice plant has a main stem and a number of tillers. Results showed that the selected CNN model had a high precision and a fast detection rate. 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). However, manual counting of productive tillers … Overall, compared to the manual counting, the accuracy of the Web app was over 99%. Jun Yu. 1. It implied both nitrogen dose and irrigation water exerted influence on the percentage of productive tillers and unproductive tillers,the Deep learning-based automatic detection of productive tillers in rice. The number of panicles in a yield component depends largely on the number of tillers (p.222. The tillering capacity of rice plants varies with variety, plant spacing, fertility, weed competition and damage from pests. The coefficients of determination between the Web app detection and manual counting of tillers were over 0.97 in all cases. The production of tertiary tillers begins at the end of secondary tiller production. 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).

In India, area under rice is 44.6 m ha with total output of 80 million tonnes (paddy) with an average productivity of 1855 kg/ha. 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. 6.80% and a higher productive tillers percentage of 93.20%, followed treatment T3, next CK1, thenthe percentage of unproductive tillers of the check treatment CK2 was highest. A tiller is a stem produced by grass plants, and refers to all shoots that grow after the initial parent shoot grows from a seed. The web app had an accuracy of over 99% compared with manual counting results. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Abstract A rice (Oryza sativa L.) crop functions as a population of tillers produced at different times and possessing specific growth characteristics. 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. The number of productive tillers decreased in the rice varieties with two times immersion (N3, N4) compared to one time immersion (N1, N2) (Table 3). Hybrid Rice Seeds.
