Water Stress Permanently Alters Shoot Architecture in Common Bean Plants
Agronomy, 2019 The effects of water stress on crop yield through modifications of plant architecture are vital to crop performance such as common bean plants. To assess the extent of this effect, an outdoor experiment was conducted in which common bean plants received ...

Morphogenic and structural responses of ryegrass cultivars under continuous stocking by beef heifers [PDF]
Ciência Rural: Most studies on ryegrass cultivars emphasize forage production and nutritional value, whereas morphophysiological differences, critical for optimizing grazing management, remain poorly understood.

Ciência Rural, 2012 O filocrono é definido como o tempo térmico necessário para o aparecimento de folhas sucessivas na haste principal de uma planta. Através do filocrono, pode-se calcular a duração do período vegetativo e, portanto, a época de florescimento em função da ...

Optimising Defoliation Frequency and Intensity to Enhance Forage Accumulation in Annual Ryegrass
Grass and Forage Science, Volume 81, Issue 4, October/December 2026.ABSTRACT To increase grazing efficiency, it is necessary to understand morphogenetic responses and how they drive forage harvest. Our objective was to evaluate defoliation frequency (time between defoliations required for the expansion of 2, 3 and 4 leaves) and intensity (low: maintenance of 50% stubble height; intermediate: maintenance of 25% stubble ...

Vernalization regulatory network identifies potential novel functions for genes in the HvVRN2 locus
New Phytologist, Volume 250, Issue 6, Page 4036-4053, June 2026.Summary Flowering is controlled by environmental and genetic factors. Vernalization requirement in barley (Hordeum vulgare L.) is determined by the allele in HvVRN1 and the presence of locus HvVRN2, which consists of two zinc‐finger and CONSTANS‐like domains (ZCCT) genes: HvVRN2a and HvVRN2b.

Agronomy Journal, Volume 118, Issue 1, January/February 2026.Abstract Phosphorus (P) is essential for maize (Zea mays L.) growth but is a limited and non‐renewable resource. Studies using DSSAT CSM‐CERES‐Maize remain scarce for low‐P soils. This study assessed maize yield response to P fertilization in P‐deficient soils using an adapted version of the DSSAT CSM‐CERES‐Maize model with minor code modifications to ...
