Winter Leaf Yellowing in 'Hass' Avocado
, 2007 The New Zealand avocado industry is worth $39.7 million in exports of 'Hass' avocados. Crop yields grew steadily from 1996 to 2001 to reach an average of 8.86 tonnes/ha. Since then however, crop yields have remained steady.

Apical leaf necrosis and leaf nitrogen dynamics in diseased leaves: a model study
, 2007 Apical leaf necrosis is a physiological process related to nitrogen (N) dynamics in the leaf. Pathogens use leaf nutrients and can thus accelerate this physiological apical necrosis.

Inheritance of flag-leaf angle, flag-leaf area and flag-leaf area duration in four wheat crosses
Theoretical and Applied Genetics, 1999 Flag-leaf angle (FLAngle), flag-leaf area (FLarea) and flag-leaf area duration (FLADuration) are important traits in determining yield in wheat (Triticum aestivum L). Genetic studies on these traits are very few. The objective of this study was to determine the gene action controlling those traits in four wheat crosses.

Monitoring environmental features using leaf stomatal characteristics [PDF]
, 1997 It is recognised that atmospheric CO(_2) concentrations are increasing, with concerns raised as to the global impact continued rises may have. Plant stomatal parameters have been suggested as a means of monitoring changing CO(_2) levels.

Heterosis studies for yield and physiological traits in rice hybrids under shallow low land condition [PDF]
Electronic Journal of Plant Breeding, 2010 Heterosis and heterobeltiosis were estimated for grain yield, its attributes and physiological traits in 33 cross combinations between rice cultivars(improved and landraces) and three male sterile parents (one wild abortive and two indigenous) generated ...

Specific leaf area and leaf area index distribution in a young Douglas-fir plantation.
, 1986 The spatial distribution of specific leaf area and leaf area index of needles in different age classes has been investigated in a young and unthinned Douglas-fir (Pseudotsugamenziesii (Mirb.) Franco) plantation in Central Italy through the destructive ...
