Improvement in Brazilian barley breeding: Changes in developmental phases and ecophysiological traits [PDF]
Frontiers in Plant Science, 2022 Despite recognizing the importance of genetic improvement in the production of barley grains, little information is available on the contribution of phenological development to the genetic improvement of Brazilian barley.

The phyllochron of well-watered and water deficit mature peach trees varies with shoot type and vigour [PDF]
AoB PLANTS, 2017 The branch construction of trees is based on phytomers, repetitive subunits defined as node + leaf + axillary meristem + internode. The rate at which phytomers are added to a shoot is termed the phyllochron, which is determined by genetics, endogenous ...

Dynamics of apex and leaf development in barley as affected by PPD-H1 alleles in two contrasting PHYC backgrounds under short or long photoperiod [PDF]
Frontiers in Plant ScienceBarley development from seedling to flowering involves both external and internal changes, the latter requiring microscopic observation. Internal changes allow for the classification of preflowering development into three phases: vegetative, early ...

Molecular-physiological model integration revolutionizes cereal flowering prediction. [PDF]
New PhytolSummary Rapid prediction and control of flowering time is essential for breeding crops resilient to changing climates. Current models often fail to predict flowering time in new cultivars because molecular models lack integration of environmental signals, while physiological models inadequately capture the interactions of vernalization, photoperiod and

Phyllochron responds to acclimation to temperature and irradiance in maize [PDF]
Field Crops Research, 1998 Crop models need accurate simulation of leaf canopy development. The thermal interval for leaf tip appearance (phyllochron) is critical for predicting the duration of vegetative development. The phyllochron in maize is shorter in temperate than in tropical and subtropical environments.

A functional–structural model of elongation of the grass leaf and its relationships with the phyllochron [PDF]
New Phytologist, 2005 The emergence of a regular phyllochron from the dynamic processes of leaf initiation, leaf elongation and whorl construction suggests causal relationships between leaf elongation and leaf emergence. This paper presents a hypothesis as to how the ontogeny of the growth zone of leaves is triggered by emergence events, and implements it in a dynamic model

Phyllochron and leaf appearance rate in oat [PDF]
Bragantia, 2017 Abstract Phyllochron and leaf appearance rate are both important parameters in the production efficiency of agricultural crops. The objectives of this study were to determine the phyllochron and leaf appearance rate in 4 oat cultivars (Avena sativa L.) in 3 sowing dates and verify the variability of phyllochron and leaf appearance rate among cultivars ...

Limitation of Maize Potential Yield by Phosphorus at the Global Scale. [PDF]
Glob Chang BiolPhosphorus (P) is a major limiting factor of crop yields at the global scale, but its contribution to the global yield gap remains uncertain. Here, we developed a simple but mechanistic model that simulates the interactions between plant growth and soil P at a daily time step, all other factors (nitrogen, water, etc.) being assumed non‐limiting ...
