Translocation and accumulation of dry matter in winter wheat genotypes
Cereal Research Communications, 2006In the years 2003 and 2004, diametrically different in temperature, in total amount of precipitation and in its distribution during vegetation, winter wheat lines in generations F 4 and F 5. originated from seven crossings, and with three local adapted varieties, were examined in field experiments. This study was conducted to assess effects of year and

Contribution of Rice Tillers to Dry Matter Accumulation and Yield
Agronomy Journal, 1998AbstractA rice (Oryza sativa L.) crop functions as a population of tillers produced at different times and possessing specific growth characteristics. The objective of this study was to characterize the contribution of cultivar tillering ability to dry matter accumulation, yield components, and grain yield.

Gas Exchange and Dry Matter Accumulation during Leaf Development
1985The primary processes of photosynthesis (see Chapter 5) supply NADPH and ATP for the fixation and reduction of carbon dioxide (see Chapter 6) which is transported into the leaf through leaf anatomical structures (see Chapter 1) characterized by different conductances for CO2 transfer (see Chapter 8).

[Dry matter accumulation in rice aboveground part: quantitative simulation].
Ying yong sheng tai xue bao = The journal of applied ecology, 2011A field experiment with four rice (Oryza sativa L.) cultivars and different nitrogen application rates was conducted, with the dry matter accumulation (DMA) in the cultivars aboveground part measured at their main growth stages. The dynamic model of relative dry matter accumulation (RDMA) was established with the normalized DMA and TEP (product of ...

Coupling of dry matter and nutrient accumulation in forage grass
Journal of Plant Nutrition, 1995Abstract The logistic model has proven very useful in relating dry matter production of forage grasses to applied nitrogen. A recent extension of the model coupled dry matter and plant ? accumulation through a common response coefficient c. The objective of this analysis was to establish the validity of the extended model for each of the three major ...

Dry Matter Accumulation in Linseed (Linum usitatissimum L.)*
Journal of Agronomy and Crop Science, 2001Field experiments were conducted at the Marfa Mawr field station of the University of Wales, Aberystwyth, over 2 years to study the effects of seeding density and row spacing on dry matter accumulation in linseed (Linum usitatissimum L.). Dry matter accumulation increased progressively in all the densities and row spacings with the age of the plants ...

Dry matter accumulation and water use relationships in wheat crops
Australian Journal of Agricultural Research, 1979In order to better understand crop growth (dry matter accumulation, DM), crop evapotranspiration (Et), and their interrelationships, we studied dryland crops of wheat (Triticum aestivum L. cv. Timgalen) sown at various dates and seeding densities in each of three years at Tamworth, N.S.W.

Dry Matter Accumulation in Kernels of Maize1
Crop Science, 1981Selection in a breeding program for physiological traits should not be initiated without knowledge of critical growth stages for the crop. The granin yield of maize (Zea mays L.) is the integral of kernel dry matter accumulation over time. The rate and duration of kernel fill have been suggested as factors which might be improved through selection and ...

Dry Matter and Nutrient Accumulation and Partitioning by Proso Millet
Agronomy Journal, 1990AbstractInformation on dry matter accumulation and nutrient uptake pattern for proso millet (Panicum miliaceum L.) is very limited. Therefore, a project was initiated to measure dry matter accumulation and N, P, K, Ca, Mg, S, Fe, Mn, Zn, and Cu uptakes in whole plants, stalks, leaves and heads of proso millet during the growing season.

Leaf Expansion Limits Dry Matter Accumulation of Salt-Stressed Maize
Australian Journal of Plant Physiology, 1994Two maize (Zea mays L.) hybrids, differing in their salt tolerance (percentage of control on a dry weight basis) and ability to accumulate Na+ in the shoot, were treated with 80 mol m-3 NaCl salinity or 80 mol m-3 NaCl plus 8.75 mol m-3 CaCl2. Multiple harvests were performed and the interactions of salinity with time were examined with growth analysis.
