Abstract:
... Leaf shape is an important factor affecting canopy structure, photosynthetic characteristics, and yield. Introducing okra leaf shape is considered an important strategy in cotton heterosis breeding. The objective of the study was to evaluate the heterosis in okra leaf cotton hybrid F₁s, which were developed by crossing two sterile near isolines and three restorer near isolines. A normal leaf check ...

Abstract:
... European natural and semi-natural grassland form reservoirs of genetic resources containing highly adapted and variable ecotype populations of forage plants. Variation within these reservoirs is stimulated by variation in natural and anthropogenic site-related factors. Changes in agricultural practices lead to the loss of many characteristic habitats. In order to preserve resources for breeding, t ...

Abstract:
... Trigonobalanus doichangensis is recognized as a rare and endangered plant of China. The morphological and physiological traits of fruits were investigated in one population over 2 years (2006-2007) and in four populations during 2007 in order to facilitate ex-situ conservation and eventual reforestation through planting of propagules. The results indicated that morphological traits including fruit ...
