TY - JOUR T1 - Total Leaf Nitrogen Correlated With Walnut Anthracnose Resistance JF - Arboriculture & Urban Forestry (AUF) JO - JOA SP - 312 LP - 314 DO - 10.48044/jauf.1986.068 VL - 12 IS - 12 AU - Dan Neely Y1 - 1986/12/01 UR - http://auf.isa-arbor.com/content/12/12/312.abstract N2 - Greenhouse studies of Juglans nigra confirmed the findings of field trials that fertilization with nitrogen reduces the severity of anthracnose caused by Gnomonia leptostyla. Total nitrogen content of leaves on seedlings of Juglans treated with a complete Hoagland’s solution, with Hoagland’s minus nitrogen, or with Hoagland’s plus nitrogen ranged from 2.14 to 4.13%. Numbers of anthracnose lesions decreased with increased leaf nitrogen content (R=0.719). ER -
