Abstract
Pycnidiospores of Diplodia gossypina competely lost their germination ability after 30 days of storage at 28℃. The organism was able to colonize on cotton bolls and survive for at least 6 months when the diseased bolls were either exposed at or buried under the soil surface.
棉鈴黑化病病原菌(Diplodia gossypina Cooke)之成熟柄孢子(pycnidiospore)在28℃溫度下貯藏30日即完全失却發芽能力。罹病棉鈴無論放置在土壤表面或埋在土內經6個月後尚能從病鈴碎片分離出本病原菌，分離率為100%。如將棉鈴曝置在未消毒土壤表面或埋在消毒土壤內經7或9個月後仍有100%分離率。12個月後無倫何種土壤及放置位置均尚有55%以上分離率。
