Sowing density effect on common bean leaf area development [PDF]

open access: yes, 2016
Sowing density is a major management factor that affects growth and development of grain crops by modifying the canopy light environment and interplant competition for water and nutrients.

Shortening generation times for winter cereals by vernalizing seedlings from young embryos at 10 degree Celsius

open access: yesPlant Breeding, Volume 142, Issue 2, Page 202-210, April 2023., 2023
Abstract Methods allowing quick generation cycles are available for various crop species but are limited to spring genotypes. However, winter types predominate in many crops including wheat and barley. Different from spring ones, winter genotypes need to be treated in low temperature for extended periods to accelerate flowering.

Genetic variation for the duration of pre-anthesis development in durum wheat and its interaction with vernalization treatment and photoperiod [PDF]

open access: yes, 2014
A recombinant inbred durum wheat population was grown under three contrasting regimes: long days following vernalization (LDV), long days without vernalization (LD), and short days following vernalization (SDV).

Variability and synchronism of leaf appearance and leaf elongation rates of eleven contrasting rice genotypes [PDF]

open access: yes, 2015
Leaf appearance and leaf elongation rates in rice play an essential role in determining the development of the plants' architecture which affects their adaptability to varying environments.

The Effect of Day to Night Temperature Variation on Leaf Development in Wheat

open access: yesPlant Production Science, 1998
The rate of leaf development in wheat is related to time and temperature in units of degree-days (DD) leaf−1 (phyllochron). Experiments were conducted in controlled environment chambers to study the effect of day to night variation in temperature on leaf

Desenvolvimento vegetativo e reprodutivo em gladíolo Vegetative and reproductive development in gladiolus

open access: yesCiência Rural, 2012
A caracterização das etapas ou fases do ciclo de desenvolvimento das culturas agrícolas é importante para realização de práticas de manejo e, para o gladíolo, essas etapas ainda não foram bem caracterizadas em cultivos a campo no Rio Grande do Sul.

BASE GROWTH TEMPERATURE AND PHYLLOCHRON FOR KIKUYU GRASS (Cenchrus clandestinus; Poaceae)

open access: yesActa Biológica Colombiana, 2021
In order to estimate the base temperature (Bt) of growth through the appearance of leaves and calculate the phyllochron for kikuyu grass, three plots were established on three farms in the Provincia of Ubaté (Cundinamarca, Colombia) located at different altitudes (2560, 2640, 3143 m. a. s. l.). Measurements were made in four cycles in a period of eight

Phyllochron and winter barley leaf growth rate

open access: yesBiologia Plantarum, 1990
Growth rate of leaves of winter barley (Hordeum vulgare L. cv. Efra) plant in thermal time correlated with the final length of the corresponding leaf (r = 0.66). The sum of effective temperatures corresponding to the time of growth of a particular leaf linearly increased with leaf insertion (r = 0.82).

Do Phytomer Turnover Models of Plant Morphology Describe Perennial Ryegrass Root Data from Field Swards?

open access: yesAgriculture, 2016
This study aimed to elucidate seasonal dynamics of ryegrass root systems in field swards. Established field swards of perennial ryegrass with white clover removed by herbicide and fertilised with nitrogen (N) to replace clover N fixation were subjected ...
