Can Meristematic Activity Determine Variation in Leaf Size and Elongation Rate among Four Poa Species? A Kinematic Study [PDF]

Plant Physiology, 2000
Abstract We studied inherent variation in final leaf size among fourPoa spp. that live at different elevations. The average final length of leaf 7 of the main stem of the smallest species (Poa alpina) was only one-half that of the largest species (Poa trivialis); it was correlated with leaf elongation rate, but not with the duration of ...

A temperature response function for modeling leaf growth and development of the African violet (Saintpaulia ionantha Wendl.)

Ciência Rural, 2004
Response functions used in crop simulation models are usually different for different physiological processes and cultivars, resulting in many unknown coefficients in the response functions. This is the case of African violet (Saintpaulia ionantha Wendl.)

Plantain (Plantago lanceolata L.) Leaf Elongation and Photosynthesis Rates Are Reduced under Waterlogging

IECAG 2023, 2023
Plantain (Plantago lanceolata L.) has been identified by the New Zealand dairy sector as an option for reducing nitrogen losses from grazed pastures. However, there is growing concern over its poor persistence. Reports have suggested that plantain does not tolerate waterlogged soils; however, there is little scientific evidence to support those claims.
