Relationship between Net CO₂ Assimilation and Dry Weight Accumulation in Field-Grown Tobacco [PDF]

Plant Physiology, 1982
To assess the variability of net photosynthetic CO(2) exchange per unit leaf area and to construct budgets for stands of field-grown tobacco (Nicotiana tabacum, Connecticut Broadleaf), a number of short-time measurements were made on all available leaf positions on two varieties using a hand-held transparent chamber for conducting gas exchange ...

Seasonal Patterns of Nutrient and Dry Weight Accumulation in Freeman Maple [PDF]

HortScience, 1999
Seasonal patterns of N, P, and K accumulation and remobilization in Freeman maple (Acer× freemanii E. Murr. `Jeffersred') were studied to guide future improvements in fertilization efficiency. Leaves, stems, and roots of container-grown trees were harvested over a 12-month period (June to June) in each of two experiments.

The Influence of Summer Pruning on Photosynthesis, Transpiration, Leaf Abscission, and Dry Weight Accumulation of Young Apple Trees1

Journal of the American Society for Horticultural Science, 1981
Abstract Young, container-grown ‘Topred Delicious’/Malling (M) 9 apple trees ( Malus domestica Borkh.) trained to a single shoot out-of-doors were summer pruned to remove 0, 25, 50 or 75% of 78 cm shoots.

Grain Yield, Dry Weight and Phosphorus Accumulation and Translocation in Two Rice (Oryza sativa L.) Varieties as Affected by Salt-Alkali and Phosphorus [PDF]

Sustainability, 2017
Salt-alkali is the main threat to global crop production. The functioning of phosphorus (P) in alleviating damage to crops from saline-alkaline stress may be dependent on the variety of crop but there is little published research on the topic. This pot experiment was conducted to study if P has any effect on rice (Oryza sativa L.) yield, dry matter and

Changes in dry weight accumulation in the Impatiens walleriana pot plant in response to different pre-transplant plug cell volume

European Journal of Horticultural Science, 2013
Summary The use of transplants is the most reliable method to ensure adequate crop establishment of commercial plantings of most ornamental bedding crops; however, in plants grown in small pots, root growth restrictions often occur.

RATE OF ACCUMULATION OF DRY WEIGHT IN SEED OF SOYBEANS AND ITS RELATIONSHIP TO YIELD

Canadian Journal of Plant Science, 1975
The dry weight accumulation rate in soybean (Glycine max (L.) Merrill) seed was measured for 2 yr (1971–72), utilizing four cultivars and several planting dates within each year. Rates observed ranged from 3.38 to 8.32 mg/seed/day. There were significant differences among cultivars and planting dates.

Statistical Models for Prediction of Dry Weight and Nitrogen Accumulation Based on Visible and Near-Infrared Hyper-Spectral Reflectance of Rice Canopies

Plant Production Science, 2000
Much information is obtainable from hyper-spectral data, which measure solar radiation consecutively at less than about 10-nm intervals. In constructing statistical prediction models, however, problems of overfitting may arise due to the excessive number of variables, and multicollinearity may occur between variables ; thus a few specific wavelengths ...

Introduction of morpho-physiological and biochemical markers to select salt-tolerant wheat (Triticum aestivum) genotypes under salinity stress. [PDF]

Desert, 2023
As a strategic crop, wheat is important to the world’s food supply. Salinity is a major threat to the food supply in the whole world and Iran. The research was carried out for identifying morpho-physiological and biochemical markers to select salt ...
