Filocrono de genótipos de arroz irrigado em função de época de semeadura Phyllochron of rice genotypes as a function of sowing date

Ciência Rural, 2007
O filocrono é definido como o tempo necessário para o aparecimento de folhas sucessivas em um colmo, no caso de espécies da família das Poáceas. Através do filocrono, pode-se calcular o número de folhas acumuladas, o que é uma excelente maneira de ...

Estimating leaf appearance rate and phyllochron in safflower (Carthamus tinctorius L.) [PDF]

Ciência Rural, 2005
Safflower may be an interesting option for the flower market, either as fresh or dried cut flower. Estimating the leaf appearance rate and the phyllochron (the time interval between the appearance of successive leaves) is important for calculating the number of emerged leaves (NL) on the plant, which is an excellent measure of plant development.

A successive time-to-event model of phyllochron dynamics for hypothesis testing: application to the analysis of genetic and environmental effects in maize. [PDF]

Plant Methods, 2023
Background The time between the appearance of successive leaves, or phyllochron, characterizes the vegetative development of annual plants. Hypothesis testing models, which allow the comparison of phyllochrons between genetic groups and/or environmental ...

Morphological and phenological adaptation for convergent development of tillers in Widely spaced wheat sown on different dates

Plant Production Science, 2021
This study analyzes the dynamics of leaf and tiller emergence and development of widely spaced wheat sown on different dates. We used the phyllochron (time interval between the emergence of successive leaves at the same stage), site filling (the relative

Corn response to long‐term seasonal weather stressors: A review

Crop Science, Volume 63, Issue 6, Page 3210-3235, November/December 2023., 2023
Abstract Long‐term weather patterns (environmental conditions or stresses exceeding 10 days in length) have the potential to influence corn (Zea mays L.) growth, development, and yield. This review summarizes the current knowledge (with emphasis placed on the Midwestern U.S. production environment) on how long‐term weather conditions affect corn growth

A multi‐level approach reveals key physiological and molecular traits in the response of two rice genotypes subjected to water deficit at the reproductive stage

Plant-Environment Interactions, Volume 4, Issue 5, Page 229-257, October 2023., 2023
Two rice genotypes were subjected to a moderate water deficit applied during the reproductive phase. Multi‐level transcriptomic, metabolomic, physiological, and morphological analyses were performed to investigate the complex traits involved in their response to drought.

Accelerated leaf appearance and flowering in maize after four decades of commercial breeding

Crop Science, Volume 63, Issue 5, Page 2750-2762, September/October 2023., 2023
Abstract Maize breeding programs have indirectly altered many plant traits; however, our knowledge of some important phenological traits remains unexplored. One such trait is leaf appearance rate, which is crucial for predicting maize development. We studied 40 short‐season (103‐day) and 38 long‐season (111‐day) hybrids released from 1980 to 2020 by ...

Water-Soluble Carbohydrate Recovery in Pastures of Perennial Ryegrass (Lolium perenne L.) and Pasture Brome (Bromus valdivianus Phil.) Under Two Defoliation Frequencies Determined by Thermal Time

Agriculture, 2020
The objectives of the experiment were to (i) examine the dynamics of WSC use and the recovery of leaf sheaths and blades of Bromus valdivianus Phil. and Lolium perenne L. subjected to two defoliation frequencies (DFs) determined by thermal time (TT); (ii)

Tiller demography of tall fescue and tall wheatgrass cut at different times during the reproductive phase

Grassland Research, Volume 2, Issue 2, Page 120-128, June 2023., 2023
The present work aimed to study the tiller demography of tall fescue (TF) and tall wheatgrass (TW) when reproductive tillers are removed at different stages of plant development. The results will help to improve management recommendations to obtain denser TF and TW swards.
