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

Phyllochron duration and changes through rice development shape the vertical leaf size profile

bioRxiv, 2022
Well-irrigated aerobic rice (Oryza sativa L.) plants are often shorter with smaller leaves, and the leaf appearance rate is slower in well-irrigated than in flooded environments.

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

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)

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

, 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 Ubate (Cundinamarca, Colombia) located at different ...

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 ...

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.
