Variation in Senescence Pattern of Different Classes of Rice Tillers and Its Effect on Panicle Biomass Growth and Grain Yield 1048 . Abstract. In order to study the effects of shallow wet–dry irrigation at tillering stage on effective tiller numbers, photosynthetic activity, yield and water use efficiency (WUE) of rice in black soil region, a pot experiment was conducted at Qingan National Irrigation Test Station of Heilongjiang Province from May to September in 2019. (1993) who stated that effective tillers/hill varied with their vari-ety. Farmers look for pest symptoms in rice tillers. More effective tillers per plant are believed to be closely associated with high seed yield per plant resulting high productivity. It is a monocot plant, normally grown as an annual crop. Proline is an amino acid which increases in plants under abiotic stress. Nitrogen deficiency reduces the plant height and number of tillers. Because of these relationships, the leaf number concept provides researchers with an effective index for studying development of shoot and root systems in rice, including the prediction of tiller morphology, the estimation of potential tiller increase, and analysis of root system dynamics. However, comprehensive analyses of the genetic basis of the tiller number, considering the development stage, tiller type, and related traits, are lacking.

Identification of suitable genotypes and their improvement can be used as a potential method to evolve salinity resistant rice genotypesfor different geographical zones. Los Banos (Philippines). However kaippad farms are decreasing in area and the traditional salt tolerant rice cultivars cultivated in the area are also slowly receding from the scene owing to low productivity. One in every three people depends on rice for more than half of their daily food (Sureka et al., 2016), Chronological of tillers and their orientation and performance in some salinity tolerant rice cultivars and varieties. It is said that a tiller of rice plant is a All rights reserved. In particular, HD1 was simultaneously associated with the productive tiller ratio and heading date, indicating that the photoperiodic heading gene directly controls the productive tiller ratio. Zhijuan QI or Zhongxue Zhang. Tiller Angle Control 1 (TAC1) is a key regulator responsible for the different tiller angles between japonica and indica rice. At 150–180 days, at least 50% of the shoots die and a stable population is established. 1. The aim was to see the effects of the weed control treatments on crop growth and yield in boro rice. Correspondence to The effective panicle number per plant, grain number per panicle, and grain weight per panicle determine the grain yield of a rice plant ( Xing and Zhang, 2010 ).

Trans Chin Soc Agric Mach 47(09):186–193, Hou JY (2014) Experiment study of water-saving irrigation model of rice introduced in Hongqiling farm of Heilongjiang province. The drip irrigation treatment had more effective tillers, more roots in topsoil, higher WUE, and greater economic benefit in rice (He, Ma, Yang, Chen, & Jia, 2013), but less yield compare with conventional flooding irrigation. Maximum tiller population is reached between 90 and 120 days after planting. Tiller production also differed significantly with the application of phosphorus fertilizer. The results showed that under water controlled conditions at tillering stage, the ineffective tiller numbers were reduced and earing rate was increased as compared to CK. While six to eight tillers are produced from a bud, it has been observed that only 1.5–2.0 tillers per bud remain to form sugarcane plants. Kaippad is such an indigenous rice-fish farming system of coastal North Kerala in India. Immediate online access to all issues from 2019. Furthermore, the model was validated using independent japonica rice collections, implying that the lead SNPs included in the linear regression model were generally applicable to the tiller number prediction.

Hayayuki . Article  Therefore, it is imperative to develop an efficient and effective in-field technology to quickly detect productive tiller numbers. Rice germinates as a single culmed seedling, but soon after the seedling stage it produces primary, secondary and tertiary tillers which come forth at different stages of growth. The tillering capacity of rice plants varies with variety, plant spacing, fertility, weed competition and damage from pests. The tiller number at different development stages and heading traits involved in phase transitions were evaluated. It is a natural system utilizing indigenous knowledge and local resources. The plants were treated with gradually increasing concentrations of NaCl varying from 0-200 mM starting from the 45th day of growth onwards mimicking the gradually increasing salt content of the salinity prone rice farms of the study area and the quantity of total phenolics was investigated in each case. Each tiller will bear a rice panicle, and you can get up to 100 grains of rice per panicle.
