Summer pruning reduces whole-canopy carbon fixation and transpiration in apple trees

KT Li, AN Lakso, R Piccioni… - The Journal of …, 2003 - Taylor & Francis
Canopy size control is one of the major purposes of summer pruning. However, reducing
canopy size might also result in less light interception, consequently decreasing canopy …

Transpiration of grapevines in the humid northeastern United States

D Dragoni, AN Lakso, RM Piccioni… - American journal of …, 2006 - Am Soc Enol Viticulture
For irrigation design and scheduling, water use of crops is commonly estimated from grass
reference evapotranspiration (ET 0 ) estimates multiplied by published crop coefficients (k c ). …

Temperature effects on fruit and shoot growth in the apple (Malus domestica) early in the season

…, AN Lakso, RM Piccioni - … Horticultural Congress: Key …, 2002 - actahort.org
Temperature is a main environmental factor affecting the net carbon exchange (NCE), carbon
balance and carbon partitioning in the apple tree. Although shoot and fruit growth and gas …

Calcium and photosynthetic oxygen evolution in cyanobacteria

RG Piccioni, DC Mauzerall - Biochimica et Biophysica Acta (BBA) …, 1978 - Elsevier
Calcium activation of oxygen evolution from French-press preparations of Phormidium
luridum is largely reversible upon removal of added Ca 2+ . Activation occurs via a first-order …

Summer pruning effects on fruit size, fruit quality, return bloom and fine root survival in apple trees

KT Li, AN Lakso, R Piccioni… - The Journal of …, 2003 - Taylor & Francis
While many undesirable effects of summer pruning on apple (Malus domestica Borkh.) growth
and development have been reported, the results are inconsistent and difficult to interpret. …

A Nuclear Mutant of Chlamydomonas reinhardtii Defective in Photosynthetic Photophosphorylation: Characterization of the Algal Coupling Factor ATPase

RG PICCIONI, NH CHUA… - European Journal of …, 1981 - Wiley Online Library
Use of the Flagyl selection procedure [Schmidt et al. (1977) Proc. Natl Acad. Sci. USA, 74,
610‐614] led to the isolation of a nuclear mutant of Chlamydomonas reinhardtiidesignated thm…

Increase effected by calcium ion in the rate of oxygen evolution from preparations of Phormidium luridum

RG Piccioni, DC Mauzerall - Biochimica et Biophysica Acta (BBA) …, 1976 - Elsevier
The presence of Ca 2+ causes a twentyfold or greater increase in the rate of oxygen evolution
by cell-free preparations of Phormidium luridum. The requirement for Ca 2+ is specific; …

Food irradiation: Contaminating our food

R Piccioni - Ecologist (London), 1988 - inis.iaea.org
[en] The nuclear industry has promoted food irradiation as an effective and safe means of
preserving food at minimum risk to the public. However, wide-scale food irradiation …

A high-potential redox component located within cyanobacterial photosystem II

RG Piccioni, DC Mauzerall - Biochimica et Biophysica Acta (BBA) …, 1978 - Elsevier
The calcium-dependent oxygen evolution activity of preparations of Phormidium luridum shows
a marked selectivity in favor of ferricyanide over benzoquinone as Hill oxidant. In addition…

Photosynthetic oxygen production

DC Mauzerall, RG Piccioni - Oxygen and Living Processes: An …, 1981 - Springer
It has been said that we exist on this earth because of an accident of quantum mechanics. It
is even more likely that we exist because of two accidents. The first is that oxygen does not …
