Accumulation of Dry Matter by Chrysanthemum morifolium after Flower Removal
Nature, 1968Sweet and Wareing1 have recently discussed the role of plant growth in controlling the rate of photosynthesis by increasing the translocation of assimilates from the leaves. We have worked with Chrysanthemum morifolium grown as a flowering pot plant2 in conditions in which the flowers became an important sink for assimilates.

Estimating dry-matter accumulation in soybean
Canadian Journal of Botany, 1977Equations to estimate gross photosynthesis, respiration, and dry-matter accumulation for soybean from daily estimates of intercepted, photosynthetically active radiation (PAR) were developed from field measurements. We found that gross photosynthesis was a function of intercepted PAR and that 24-h dark respiration was a function of gross ...

Prediction of dry matter accumulation in bitter vetch
LEGUME RESEARCH - AN INTERNATIONAL JOURNAL, 2017This study was carried out in Bingol province on eastern Anatolian Region between 2013 and 2015. In this study, we obtained 14 bitter vetch genotypes from different sources. The experiment was carried our in three replications in randomized block design. Each plant was weekly measured for 6 weeks starting from germination. For each plant, plant height,

Coupling of dry matter and nitrogen accumulation in ryegrass
Fertilizer Research, 1995The logistic model has proven very useful in relating dry matter production of warm season perennial forage grasses to applied nitrogen. A recent extension of the model coupled dry matter and plant N accumulation through a common response coefficient c.

Dry Matter Accumulation Predictors for Optimal Yield in Soybean
Crop Science, 2005Identification 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 ...

Accumulation and Partitioning of Dry Matter in Water Yam
Agronomy Journal, 1994AbstractThere is a scarcity of field‐growth data from which a yam (Dioscorea alata L.) growth model could be developed to promote agrotechnology transfer of the crop in the tropics. A 2‐yr field study was conducted on Corozal soil (clayey mixed isohyperthermic Aquic Tropudults) in an initial effort to collect data on patterns of leaf area development ...

Response of Dry Matter Accumulation in Maize to Temperature: I. Dry Matter Partitioning
Crop Science, 1989Dry matter partitioning during early phases of development has potentially a large impact on crop growth, but the effect of partitioning on dry matter accumulation has never been quantified. This study was conducted to quantify the response of dry matter partitioning in maize (Zea mays L.) to temperature during the period from planting to the 12‐leaf ...

Dry Matter Production and Carbohydrate Accumulation in Three Meadowfoam Lines
Crop Science, 1991The literature lacks information on seasonal patterns of meadow foam (Limnanthes R. Br. spp.) dry matter production and nonstructural carbohydrate quantities and their relationship with seed yield. To provide this information, three meadow foam lines (85‐765, 85‐729 and ‘Mermaid’) with contrasting seed yield performance were grown in 1987‐1988 and 1988‐

Dry Matter Accumulation and Dinitrogen Fixation of Annual Medicago Species
Agronomy Journal, 1998AbstractAssessment of the N2 fixation potential of annual medics (Medicago spp.) in the upper Midwest is important for predicting the net N contribution to cropping systems. Our objectives were to determine the dry matter (DM) accumulation pattern of herbage, roots, and nodules of several annual medic species used as summer annuals and to measure the ...
