The effects of day and night temperature on Chrysanthemum morifolium: investigating the safe limits for temperature integration [PDF]

open access: yes, 2009
The impact of day and night temperatures on pot chrysanthemum (cultivars ‘Covington’ and ‘Irvine’) was assessed by exposing cuttings, stuck in weeks 39, 44, and 49, to different temperature regimes in short-days. Glasshouse heating setpoints of 12°, 15°,

Brassinosteroid regulation of plant height in maize

open access: yes, 2018
Brassinosteroids (BRs) are a type of phytohormone that has important roles in plant development. Even though they are well studied in model species, their role in maize development is poorly understood. To address this issue, two approaches were undertaken.

Control of Salpiglossis sinuata Height with Plant Growth Regulators [PDF]

open access: yesHortScience, 1990
Salpiglossis sinuata R. et P., a floriferous member of the Solanaceae, was studied for potential as a flowering potted plant when modified by growth retardants. Seedlings of an inbred line P-5 were covered with black cloth for an 8-hour photoperiod to permit vegetative growth to ≈16 -cm-diameter rosettes.

Foliar and wood traits covary along a vertical gradient within the crown of long-lived light-demanding species of the Congo Basin semi-deciduous forest [PDF]

open access: yes, 2019
Plant functional traits have shown to be relevant predictors of forest functional responses to climate change. However, the trait-based approach to study plant performances and ecological strategies has mostly been focused on trait comparisons at the ...

Crown Area as a Parameter for Biomass Estimation of Croton sonderianus Müll. Arg.

open access: yesFloresta e Ambiente
Current tree biomass estimation techniques generally use remote sensing data and allometric models for validation, which relate non-destructive parameters to plant biomass, usually employing diameter at the plant base or breast height and plant height ...
