Turgor‐time controls grass leaf elongation rate and duration under drought stress [PDF]
Plant, Cell and Environment, 2021 AbstractThe process of leaf elongation in grasses is characterized by the creation and transformation of distinct cell zones. The prevailing turgor pressure within these cells is one of the key drivers for the rate at which these cells divide, expand and differentiate, processes that are heavily impacted by drought stress.

Components of leaf elongation rate and their relationship to specific leaf area in contrasting grasses [PDF]
New Phytologist, 2003 Summary In grasses the leaf growth zone is the main site of shoot growth where anatomical and chemical characteristics of leaves originate. Yet, there is insufficient information to generalize as to whether the leaf growth zone reflects habitat characteristics, whether leaf growth traits are regularly interrelated, and whether they coincide with ...

Genotypic differences for temperature response of leaf appearance rate and leaf elongation rate in field-grown maize [PDF]
Agronomie, 1995 La mise en place du systeme foliaire est le principal facteur limitant le rendement dans les regions caracterisees par un printemps long et frais telles que l'Europe du Nord. L'objectif de ce travail etait d'etudier l'influence de la temperature sur le developpement et la croissance foliaires.

The elongation rate at the base of a maize leaf shows an invariant pattern during both the steady‐state elongation and the establishment of the elongation zone [PDF]
Journal of Experimental Botany, 2001 Spatial and temporal analyses of elongation and cell length of monocotyledon leaves have most often been performed during the period when leaves are visible and elongate at a constant rate (steady-state). In the present study, the focus was on the earlier stages, during the establishment of the elongation zone. Regardless of leaf development stage, the

Two maize cultivars of contrasting leaf size show different leaf elongation rates with identical patterns of extension dynamics and coordination [PDF]
AoB PLANTS, 2021 Abstract Simulating leaf development from initiation to maturity opens new possibilities to model plant–environment interactions and the plasticity of plant architecture. This study analyses the dynamics of leaf production and extension along a maize (Zea mays) shoot to assess important modelling choices.

RATE OF LEAF ELONGATION AS AFFECTED BY THE INTENSITY OF THE TOTAL SOIL MOISTURE STRESS [PDF]
Plant Physiology, 1948 Recent studies (1, 7, 9) have indicated that an interrelationship exists between soil salinity and the soil moisture content in their effect on plant growth. These two factors may be logically evaluated in terms of the decrease in the specific free energy of the soil moisture. Thus, salinity may be expressed in terms of the osmotic pressure of the soil

Computers and Electronics in Agriculture, 2023 Flag leaf growth has been emphasized in the literature as an important secondary trait for wheat breeding under drought stress. To measure leaf elongation rate (LER) in monocotyledons such as wheat, the rotational displacement transducer (RDT) has already been used in several studies, mostly on maize.

Morphogenetic, structural and production traits of marandu grass under nitrogen rates in Neo soil
Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2021 Most sandy soils have low natural fertility and low levels of organic matter, making nitrogen (N) fertilization essential. Thus, five doses of N were applied (0, 75, 125, 175 and 225mg dm-³) in a randomized block design to evaluate the effects of ...

Diurnal Changes in Maize Leaf Photosynthesis [PDF]
Plant Physiology, 1987 Maize (Zea mays L. cv. Pioneer 3184) leaf elongation rate was measured diurnally and was related to diurnal changes in the activities of sucrose metabolizing enzymes and carbohydrate content in the elongating portion of the leaf. The rate of leaf elongation was greatest at midday (1300 hours) and was coincident with the maximum assimilate export rate ...
