Correlation between macronutrient content and sunflower resistance to Sclerotinia sclerotiorum measured by sclerotia infection of stem
(Paris : International Sunflower Association, 2008)
Nutrition of plants has a substantial impact on the predisposition of plants to be attacked or affected by pests and diseases. Since availability and nutrient quantity in the host plants is a limiting factor for Sclerotinia ...
Estimation of combining abilities in sunflower (Helianthus annuus L.)
(Paris : International Sunflower Association, 2012)
In commercial production, sunflower hybrids are more represented than open pollinated varieties. The basic advantage of hybrids over varieties is that the hybrids allow the use of heterosis. Sunflower hybrids are more ...
