Ciência Rural, 2012 O desenvolvimento de plantas, influenciado pela temperatura do ar, pode ser estimado através do conceito de filocrono, definido como o intervalo de tempo entre o surgimento sucessivo de folhas em uma haste, sendo o tempo expresso em °C dia e o filocrono ...

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.

Soybean seed yield distribution within the canopy as affected by nitrogen supply
Crop Science, Volume 65, Issue 2, March/April 2025.Abstract Soybean (Glycine max [L.] Merr.) seed yield is influenced by the seasonal availability of resources (i.e., nutrients, light, and water). While nitrogen (N) supply is becoming a soybean yield‐limiting factor, the N‐induced effect in seed yield components is still unclear.

Plant, Cell &Environment, Volume 47, Issue 12, Page 5067-5075, December 2024.Abstract By regulating carbon uptake and water loss by plants, stomata are not only responsible for productivity but also survival during drought. The timing of the onset of stomatal closure is crucial for preventing excessive water loss during drought, but is poorly explained by plant hydraulics alone and what triggers stomatal closure remains ...

Expansión y recambio foliar de gramíneas perennes C4 creciendo a temperaturas moderadamente bajas [PDF]
, 2016 Understanding the mechanisms by which some C4 grasses grow more than others at moderately low temperatures (~12-20°C) is valuable to select materials to lengthen the growing season. In turn, the determination of leaf lifespan for each material to be used

A Functional Analysis of Inflorescence Architecture in Musa L. (Musaceae)
Food and Energy Security, Volume 13, Issue 5, September/October 2024.ABSTRACT Inflorescence architecture underpins sexual reproduction in wild Musa species and productivity in edible banana cultivars. In a functional analysis, we identified the apical inflorescence and lateral ‘cushion’ meristems and the change in flower type as the three primary components that generate inflorescence architecture. Five genotypes of two

Agronomy Journal, Volume 116, Issue 4, Page 1844-1868, July/August 2024.Abstract Crop models are valuable tools for simulating and assessing genotype‐by‐environment interactions. In most studies, these models are parameterized based on crop data from a few sites and years, which often limits their applicability to a broader geographic context.

Towards a Robust Method of Modelling Leaf Appearance in Plants [PDF]
, 1998 The thermal interval for leaf tip appearance (phyllochron) is a critical variable for modelling plant development and growth. Phyllochron varies across environments, but is generally constant for a species grown in specific environments. For example, the

Response of seeding rate and cultivar maturity with planting dates in canola
Agronomy Journal, Volume 116, Issue 3, Page 1382-1396, May/June 2024.Abstract Understanding whether increasing seeding rate in canola (Brassica napus) provides a yield‐compensatory mechanism with delayed planting due to weather or logistical issues is important. We aim to refine agronomic recommendations for canola production under short‐season growing conditions to establish an optimal planting date and identify any ...
