Effects of irradiance during growth on tolerance of geranium to sub- and supra-optimal boron supply

open access: yesBiologia Plantarum, 2014
In our previous study on geranium, we showed that increases in growth irradiance from sub-optimal to near-optimal could delay boron deficiency effects on photosynthesis. In this study, we further investigated the effects of growth irradiance on tolerance

Photosynthetic and leaf anatomical characteristics of Castanea sativa: a comparison between in vitro and nursery plants

open access: yesBiologia Plantarum, 2012
The anatomic and functional leaf characteristics related to photosynthetic performance of Castanea sativa growing in vitro and in nursery were compared. The irradiance saturated photosynthesis in in vitro grown plantlets was significantly lower compared ...

The Influence of Age, Position, and Environmental Variables on Net Photosynthetic Rate of Sour Cherry Leaves1

open access: yesJournal of the American Society for Horticultural Science, 1982
Abstract Net photosynthetic rate (Pn) of leaves of sour cherry ( Prunus cerasus L. cv. Montmorency) was greater for leaves between nodes 9 and 13 than for either older, mature leaves or newly expanding leaves on the same shoot.

Net photosynthetic CO2 assimilation: more than just CO2 and O2 reduction cycles

open access: yes, 2019
Net photosynthetic assimilation in C3 plants is mostly viewed as a simple balance between CO2 fixation by Rubisco‐catalyzed carboxylation and CO2 production by photorespiration (and to a lower extent, by day respiration) that can be easily manipulated ...
