CHANGES WITH AGE IN THE PHOTOSYNTHETIC AND RESPIRATORY COMPONENTS OF THE NET ASSIMILATION RATES OF SUGAR BEET AND WHEAT [PDF]
New Phytologist, 1966 SummaryThe net assimilation rates (E) of sugar beet and wheat growing in a controlled environment, and their components, the rates of photosynthesis (P) and respiration (R) of the whole plant per unit leaf area, were determined at intervals by a method described previously that depends on measuring the decrease in E when photosynthesis is prevented on ...

Agricultural Water Management, 2023 Biochar has been increasingly recognized as a valuable soil conditioner, which is beneficial to peanut yield improvement. We conducted a three-year field experiment to investigate the effect of biochar applied at three rates (0 t ha−1 (B0), 24 t ha−1 (B1)

Net Photosynthetic Rates and Growth of Strawberry after Partial Defoliation
HortScience, 1988 Abstract Leaf loss increased net photosynthesis (Pn) or delayed senescence of the remaining leaves in several plant species (2, 3, 7, 8). Strawberries are commonly defoliated during planting and after fruiting. The objective of this study was to determine the effects of partial defoliation on Pn rates and growth of the strawberry.

Net Photosynthetic and Evapotranspiration Rates in Situ of Tomato and Lettuce Plug Sheets in the Greenhouse [PDF]
HortScience, 1995 Net photosynthetic and evapotranspiration rates of tomato (LAI = 2.3) and lettuce (LAI = 6.6) plug sheets were estimated based on measurements of the weight of plug sheets and vertical profiles of CO2 concentration above the plug sheets. The measurements were continued in situ for several days in a greenhouse when plugs were at transplant stage.

Photosynthetic responses of three common mosses from continental Antarctica [PDF]
, 2005 Predicting the effects of climate change on Antarctic terrestrial vegetation requires a better knowledge of the ecophysiology of common moss species. In this paper we provide a comprehensive matrix for photosynthesis and major environmental parameters ...

Growth and Net Photosynthetic Rate of Tomato Plantlets during Photoautotrophic and Photomixotrophic Micropropagation [PDF]
HortScience, 2001 Nodal explants of tomato ( Lycopersicon esculentum Mill.) were cultured in vitro to evaluate the effects of sugar concentration, photosynthetic photon flux ( PPF ), CO 2 concentration, ventilation rate of the ...

Photosynthetic mechanism of high yield under an improved wide-narrow row planting pattern in maize
Photosynthetica, 2022 Wide-narrow row maize planting patterns are a popular way to enhance maize yield via improving canopy PAR. To further optimize canopy PAR, we designed an improved wide-narrow row planting pattern (R2) based on the principle of the shortest projection ...
