Dry matter partitioning and physiological responses of Coffea arabica varieties to soil moisture deficit stress at the seedling stage in Southwest Ethiopia M. Worku1 and T. Astatkie2* 1Department of Horticulture and Plant Sciences, College of Agriculture and Veterinary Medicine, Jimma University, P. O. Box , Jimma, Ethiopia. The accumulation and partitioning of dry matter in two improved taro cultivars (Samoa 1 and Samoa 2) were determined to characterise their growth and development patterns. A split- split-plots experiment in a RCBD design with three replications was setup to determine the dry matter accumulation and partitioning of the two cultivars. Intensively growing shoots modified the dry matter partitioning: during shoot growth the proportion of roots decreased but after that it increased. Based on their large proportion of dry matter, the needles (excluding current needles) were the strongest sink of carbon containing 40% of the incorporated 14 C.

At the initial stages of tuberization, the balance of dry matter partitioning starts to shift from the shoot to the tubers. . Mar 27, · There was no evidence of a discontinuity in the partitioning between root and shoot at any point in crop development. It is suggested that, contrary to a recent view, events in the shoot, rather than the storage root, largely determine how dry matter is allocated between growth and sugar laportadelvino.com by: Accumulation and Partitioning of Dry Matter in Water Yam Article (PDF Available) in Agronomy journal 86(6) · January with 38 Reads DOI: /agronjx. nitrogen. Sources, methods and timing of nitrogen application had significantly influenced dry matter partitioning at pre-anthesis stage, at physiological maturity and final yield. In case of sources of nitrogen higher dry matter partitioning at pre-anthesis stage to leaf ( g m-2), stem ( g m-2), spike. Dry matter partitioning and morphology of the different parts of plant as a function of its physiological achievement are used to explain the differences in relative growth rate RGR. Relating the differences in RGR to dry matter partitioning has been reported (Poorter et al. ). Dry matter partitioning and seeding depth. The mean percentage dry matter partitioning was greatest for roots (%), followed by leaves (%) and stems (%) (Table 1). This partitioning for roots is similar to that reported previously in 11 experiments where it ranged from % to %.Cited by: 1. 𝗣𝗗𝗙 | Total dry matter (TDM) and nutrient accumulation, nutrient partitioning, and cumulative growing degree days at the time of maximum nutrient accumulation for two‐row spring barley. Phosphorus (P) and zinc (Zn) deficiencies are the major problems that decrease crop productivity under rice-wheat cropping system. Field experiments were conducted to investigate impacts of P (0, 40, 80 and kg/hm 2) and Zn levels (0, 5, 10 and 15 kg/hm 2) on dry matter (DM) accumulation and Cited by: 8. The dry matter or dry weight is a measurement of the mass of something when completely dried. The dry matter of plant and animal material consists of all its constituents excluding water. The dry matter of food includes carbohydrates, fats, proteins, vitamins, minerals, and antioxidants (e.g., thiocyanate, . © Scienceweb Publishing Regulation effects of water and nitrogen on potato dry matter and nitrogen accumulation and partitioning Li Wen-ting1,2 • Wang Shi-wen1,3* • Deng Xi-ping1,3 • Yin Li-na1,3 • Li Hong-bing1,3 1State Key Laboratory of Soil Erosion and Dryland Farming on the Loess Plateau, Author: Li Wen-ting, Wang Shi-wen, Deng Xi-ping, Yin Li-na, Li Hong-bing. Dry matter partitioning in shoots and roots increased by high light intensity ( µmol m -2 s -1) and low temperature (15°C) whereas the shoot:root ratio increased with low light intensity ( Key words: Dry matter distribution, glasshouse, model, partitioning, simulation, sink strength, temperature, tomato, TOMSIM, validation. INTRODUCTION An important limitation of crop growth models is their weakness in simulating dry matter partitioning (Challa, ; Evans, ). Many theories have been put forwardCited by: nitrogen. Sources, methods and timing of nitrogen application had significantly influenced dry matter partitioning at pre-anthesis stage, at physiological maturity and final yield. In case of sources of nitrogen higher dry matter partitioning at pre-anthesis stage to leaf ( g m-2), stem ( g m-2), spike. model for dry matter accumulation and partitioning and yield accumulation by analysing dry matter partitioning in processing tomatoes using data obtained from different growth years and cultivars. Tests with different data sets involving different cultivars and sowing dates showed that the model gave reliable predictions and was practicable. Dry matter partitioning and yield formation are key points for successful simulation of seed yield.

Nov 2, PDF | p>An experiment was conducted at the research field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur Summary In mechanistic growth models, the description of assimilate allocation or dry matter partitioning plays a key role. Although theoretical concepts of. dry matter (DM) partitioning into stems, leaves and spikes, in response to multiple abiotic Key words: Abiotic stress; Dry matter partitioning; models; wheat. At the initial stages of tuberization, the balance of dry matter partitioning starts to shift from the shoot to the tubers. At the early stages of this shift, tuber initiation is . For the last several years, research in my laboratory has been focused on studying the developmental and environmental control of dry-matter partitioning in.
