Importance of the Phyllochron in Studying Development and Growth in Grasses
Crop Science, 1995The phyllochron, which is defined as the interval between similar growth stages of successive leaves on the same calm, has been used extensively to describe and understand development of grasses. The purpose of this paper is to introduce seven papers presented as part of the symposium Understanding Development and Growth in Grasses: Role of the ...

Quantitative trait loci for phyllochron and tillering in rice
Theoretical and Applied Genetics, 2004Morphogenetic processes in sequentially growing leaves and tiller buds are highly synchronized in rice ( Oryza sativa L.). Consequently, the appearance of successive leaves in the main tiller acts as the "pacemaker" for the whole shoot system development.

Phyllochron Differences in Wheat, Barley, and Forage Grasses
Crop Science, 1995The phyllochron is a measure of rate of development of plant leaves. Knowledge of the phyllochron for crop species is useful in formulating simulation models and for tracking plant development to determine when to apply management practices that depend on crop development stage. Our objectives were to determine the phyllochron and genetic effects among

The vexatious problem of the variation of the phyllochron in wheat
Field Crops Research, 2008Abstract Measurements of the thermal phyllochron in wheat using air temperature show a systematic variation with sowing date, with long phyllochrons for crops sown in autumn and winter, but shorter phyllochrons for sowings outside that range. Based on the hypothesis that the phyllochron is constant, two sources of error for the apparent variation in ...

Inheritance of Phyllochron in Barley
Crop Science, 1999Phyllochron, defined as the time between elongation of successive leaves, influences the development of cereals. Small phyllochron may be advantageous for barley (Hordeum vulgare L.) grown in cool or short‐season conditions, in order to increase the number of leaves produced from a given number of heat units, usually measured in growing degree days ...

Sensitivity of Winter Wheat Phyllochron to Environmental Changes
Agronomy Journal, 1994AbstractThe effect of environmental changes on the rate of leaf emergence in wheat (Triticum aestivum L .) must be understood to accurately simulate the development of the crop canopy. We determined the phyllochron for ‘Stephens’ winter wheat plants in growth chambers at two constant temperatures (10 and 18 °C) at a daylength of 14 h and at two ...

Phyllochron Dynamics Under Controlled Environments in Rice (Oryza Sativa L.)
Euphytica, 2006Previously, we reported that phyllochron of rice greatly fluctuated in the course of development under natural conditions. The present study was carried out to examine the phyllochron dynamics using the five near-isogenic lines (NILs) for heading time and the recurrent parent.

Phyllochron Change in Winter Wheat with Planting Date and Environmental Changes
Agronomy Journal, 1991AbstractThe phyllochron (degree‐days/leaf) of wheat (Triticum aestivum L.) differs with planting dates and latitudes. An understanding of the causes for these differences is needed to model the development of wheat crop canopies. Stephens and Yamhill winter wheat cultivars were planted on a range of dates in outdoor pots and in field plantings to study
