Water Stress Permanently Alters Shoot Architecture in Common Bean Plants

Agronomy, 2019
The effects of water stress on crop yield through modifications of plant architecture are vital to crop performance such as common bean plants. To assess the extent of this effect, an outdoor experiment was conducted in which common bean plants received ...

Accuracy of Equations Predicting the Phyllochron of Wheat

Crop Science, 1995
Predicting the rate of leaf appearance, or phyllochron, aids in understanding and modeling grass development and growth. Nine equations predicting the phyllochron of wheat (Triticum aestivum L.) were evaluated using field data from a variety of locations, cultivars, and management practices.
