Morphogenetic and structural characteristics of clones of elephant grass managed under intermittent stocking [PDF]

Semina: Ciências Agrárias, 2016
This work was carried out to evaluate the morphogenetic and structural characteristics of basal and aerial tillers of two dwarf elephant grass clones (BRS Kurumi and CNPGL 00-1-3) managed under intermittent stocking in six grazing cycles.

Leaf appearance rate and final main stem leaf number as affected by temperature and photoperiod in cereals grown in Mediterranean environment

Italian Journal of Agronomy, 2017
In the present study, a two-year field trial was carried out with the aim to evaluate daylength and air temperature effects on leaf appearance and related rates in two durum wheat (Triticum durum Desf.), two bread wheat (Triticum aestivum L.) and two ...

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 ...

Approaches to Modeling Potato Leaf Appearance Rate [PDF]

Agronomy Journal, 2006
Two approaches quantifying potato (Solanum tuberosum L. cv. Kennebec) leaf appearance rates were evaluated: a thermal time approach using the phyllochron, and a nonlinear temperature response approach using a modified β distribution function. Leaf appearance measurements at six temperature treatments (14/10, 17/12, 20/15, 23/18, 28/23, and 34/29°C ...

Leaf appearance rate and phyllochron on millet sowing dates

REVISTA BRASILEIRA DE MILHO E SORGO, 2023
The objective of this study was to determine the leaf appearance rate and phyllochron as affected by millet sowing dates. The experiment was conducted with six sowing dates (11/28/2019, 12/03/2019, 12/10/2019, 12/17/2019, 12/30/2019 and 01/14/2020). The sowing was performed in plots with six rows of 2 m length and spacing of 0.25 m between rows.

Genotypic differences for temperature response of leaf appearance rate and leaf elongation rate in field-grown maize [PDF]

Agronomie, 1995
La mise en place du systeme foliaire est le principal facteur limitant le rendement dans les regions caracterisees par un printemps long et frais telles que l'Europe du Nord. L'objectif de ce travail etait d'etudier l'influence de la temperature sur le developpement et la croissance foliaires.

Incorporating a Chronology Response into the Prediction of Leaf Appearance Rate in Winter Wheat [PDF]

Annals of Botany, 2003
The prediction of leaf appearance rate (LAR) is an important part of many crop simulation models. Most wheat simulations models assume that LAR is affected by temperature and photoperiod. This assumption ignores the fact that seed reserves contribute to a greater LAR of the first two leaves and that the LAR of subsequent leaves decreases as a result of

Morphogenesis in guinea grass pastures under rotational grazing strategies

Revista Brasileira de Zootecnia, 2012
This study was conducted in order to evaluate the morphogenetic and structural characteristics of guinea grass cv. Mombasa under three post-grazing heights (intense - 30 cm, lenient - 50 cm and variable - 50 in spring-summer and 30 cm in autumn-winter ...

CO2Effects on Phasic Development, Leaf Number and Rate of Leaf Appearance in Wheat [PDF]

Annals of Botany, 1997
It has been predicted that the concentration of CO2in the air could double during the 21st century. Though it is recognized that CO2-doubling could increase yield through its effects on plant photosynthesis and stomatal behaviour, it is unclear whether CO2-doubling will change phasic development in wheat.

Longer cutting intervals on the characteristics of Guinea grass: morphogenetic, productive, and nutritional traits

Acta Scientiarum: Animal Sciences, 2023
The aim of this study was to examine the effect of longer cutting intervals on morphogenetic and structural traits, herbage production, nutritional value, and in vitro digestibility of Guinea grass cv. Mombaça (Mombaça grass). Four cutting intervals (49,
