Rates of leaf appearance and panicle development in rice (Oryza sativa L.): a comparison at three temperatures

open access: closedAgricultural and Forest Meteorology, 1993
Abstract Plants of rice ( Oryza sativa L., cv. IR36) grown in controlled environment cabinets in free-draining or waterlogged pots at 20, 24 or 28°C with a photoperiod of 11.5 h day −1 were harvested serially and dissected in order to monitor leaf appearance and panicle development on the main culm.

Effect of Temperature on Rate of Leaf Appearance and Flowering Date in Maize1

Crop Science, 1979
Classification of development in maize (Zea mays L.) based on temperature is important because of the need in agriculture to determine the adaptability of genotypes to particular environments and to predict flowering dates for breeding purposes. An equation predicting the effect of temperature on rate of development of maize was obtained by measuring ...

Quantitative analysis of maize leaf collar appearance rates

Plant Physiology and Biochemistry, 2023
Phyllochron, the reciprocal of the leaf appearance rate, is a critical genetic parameter in crop models for predicting growth characteristics and yield. Previous studies have shown that existing observations and predictive algorithms do not adequately represent a broad range of cultivars and environments.

Corn Growth Response to Temperature and Photoperiod II. Leaf‐Initiation and Leaf‐Appearance Rates1

Agronomy Journal, 1983
AbstractThe prediction of evapotranspiration and canopy photosynthesis, for example in crop simulation modeling and in remote sensing applications, requires a quantitative description of the influence of environmental factors such as temperature and photoperiod on leaf area development.

Leaf Appearance Rates of Two Winter Wheat Cultivars under High Carbon Dioxide Conditions

Agronomy Journal, 1990
AbstractThe mechanisms describing leaf appearance and tillering are vital to the modeling of wheat canopy development. How these two factors will be affected by increasing global atmospheric [CO2] in cool or warm climates is not fully understood. Two southeastern USA adapted wheat (Triticum aestivum, L.) cultivars, Coker 762 and Stacy, were grown under
