Germination Helianthus annuus seed size NaCl seed vigor
2009/3/4
In recent years, the use of sunflower seeds sorted by seed size has been extensively increased in Turkey but little is known about the effects of seed size on germination, emergence, seedling gr...
Effects of variety and row spacing on radiation interception, partitioning of dry matter and seed set efficiency in late season sunflower（Helianthus annuus L.）in a humid zone of Nigeria
Sunflower cultivars late season RUE extinction coefficient plant-plant variability
2009/3/3
In the tropics, crops sown in the late season are subjected to concurrent stresses of high air and soil temperatures, large saturation vapour pressure deficits and negligible soil water regimes. The r...
