Contribution of Rice Tillers to Dry Matter Accumulation and Yield

Agronomy Journal, 1998
AbstractA 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.

Dry Matter Accumulation Predictors for Optimal Yield in Soybean

Crop Science, 2005
Identification of predictors for soybean [Glycine max (L.) Merr.] optimal yield (4500 kg ha−1 for Louisiana growing conditions) would help farmers identify profitability and aid in determination of environmental factors limiting crop yield. Since environmental influences on yield act mainly through effects on total dry matter (TDM) accumulation during ...

Coupling of dry matter and nutrient accumulation in forage grass

Journal of Plant Nutrition, 1995
Abstract 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 ...

An analysis of the accumulation of water and dry matter in tomato fruit

Plant, Cell & Environment, 1987
Abstract Previously published data from tomato plants grown in nutrient solutions having one of three electrical conductivities (2, 12 and 17 mS cm−1) were analysed. The rate of water import into the fruit, and the proportion of this conducted by the xylem stream were calculated from the daily rates of transpiration and the net accumulation of water ...

Model for accumulation of dry matter and plant nutrients by corn

Communications in Soil Science and Plant Analysis, 1999
Abstract Accumulation of dry matter by warm‐season annuals depends upon time of season, including planting time. A mathematical model has been developed to simulate the growth process. The model contains a Gaussian environmental function and a linear‐exponential intrinsic growth function.

Accumulation and Redistribution of Dry Matter and Nitrogen by Spring Barley

Agronomy Journal, 1993
AbstractThe grain protein content of barley (Hordeum vulgare L.) is derived from the retranslocation of vegetative N, as well as from the continued uptake and assimilation of N during grain filling. Field trials were conducted at the E.A. Lods Agronomy Research Centre of McGill University on a a Bearbrook soil (fine, mixed, nonacid, frigid Humaquept ...

Dry Matter and Nutrient Accumulation and Partitioning by Proso Millet

Agronomy Journal, 1990
AbstractInformation 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.

Coupling of dry matter and nitrogen accumulation in millet and ryegrass

Communications in Soil Science and Plant Analysis, 1997
The logistic model has proven very useful in relating dry matter production of warm‐season and cool‐season forage grasses to applied nitrogen (N).

Accumulation and partitioning of dry matter and mineral nutrients in developing kiwifruit vines

Tree Physiology, 1987
Size, dry weight and mineral nutrient content of fruit, leaves, shoots, canes, leader, stem and roots of kiwifruit (Actinidia deliciosa (A. Chev.) C.F. Liang et A.R. Ferguson var. deliciosa) vines, aged from one to five years, were measured. The distribution of fruit yield among single canes was examined in three of the vines.

Effect of Lanthanide Chloride on Photosynthesis and Dry Matter Accumulation in Tobacco Seedlings

Biological Trace Element Research, 2001
To investigate the physiological effects of rare earth ions, we have studied the effect of LaCl3 on the photosynthetic light reactions in tobacco (Nicotiana tobacum). When treated with 5-20 mg/L LaCl3 in Hoagland solution by water culture, the dry matter accumulation of different parts in tobacco, the content of chlorophyll increased gradually, but ...
