Phyllochron estimate for the teosinte crop

Sigmae, 2023
O objetivo deste trabalho foi estimar o filocrono para a cultura de teosinto em datas de semeadura. Foi conduzido um experimento em 12 datas de semeadura (08/10/2021 a 01/01/2022). As semeaduras foram realizadas em uma fileira de 5 m de comprimento, espaçadas em 0,80 m entre fileiras e 0,20 m entre plantas na fileira. Em cada data de semeadura marcaram-

Quantitative trait loci for phyllochron and tillering in rice

Theoretical and Applied Genetics, 2004
Morphogenetic 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.

Vernalization and Phyllochron in Winter Wheat

Agronomy Journal, 1991
AbstractPhyllochron (degree‐days/leaf) has been used to describe phasic leaf development in dynamic wheat (Triticum aestivum L.) crop development models. Vernalization controls the rate of crop development in winter wheat. The objective of this experiment was to determine whether vernalization affected the thermal time required for winter wheat to ...

Phyllochron Differences in Wheat, Barley, and Forage Grasses

Crop Science, 1995
The 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

Sensitivity of Winter Wheat Phyllochron to Environmental Changes

Agronomy Journal, 1994
AbstractThe 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 Response to Vernalization and Photeperiod in Spring Wheat

Crop Science, 1995
An understanding of how environment controls the initiation and development of the leaf is required to construct dynamic crop simulation models. The aim of this study was to determine the effect of vernalization and photoperiod on total number of leaves at anthesis, leaf emergence rate, and phyllochron in 20 spring wheat genotypes (Triticum aestivum L.)

The Phyllochron: Where Do we Go in the Future?

Crop Science, 1995
This paper integrates, expands, and applies information from seven articles written for a symposium on the use of phyllochron concepts for describing shoot development in grasses. Generally, no one environmental factor is a perfect predictor of plant development rate.

Inheritance of Phyllochron in Barley

Crop Science, 1999
Phyllochron, 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 ...

Phyllochron Dynamics Under Controlled Environments in Rice (Oryza Sativa L.)

Euphytica, 2006
Previously, 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.

Phytomers, phyllochrons, phenology and temperate cereal development

The Journal of Agricultural Science, 2005
Extensive research has been conducted on temperate cereal development since the inception of the Journal of Agricultural Science, Cambridge in 1905. This review presents an overview of the orderly and predictable development of wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.). It begins with the concept of building canopies by the formation,
