Popis: ペピーノを台木に用いたトマトの青枯病および萎凋病に対する発病抑制効果を検討した。青枯病Ⅰ~Ⅴ群菌にそれぞれ属する15菌株を接種したところ,ペピーノ‘ゴールドNo.1’およびペピーノ台接ぎ木トマト(‘大型福寿’/‘ゴールドNo.1’)では,外部病徴および導管褐変は認められなかった。トマト萎凋病レース1,2および3の菌株を接種したところ,ペピーノ‘ゴールドNo.1’およびペピーノ台接ぎ木トマト(‘大型福寿’/‘ゴールドNo.1’)では,外部病徴および導管褐変は認められなかった。以上,ペピーノ‘ゴールドNo.1’をトマトの台木として用いることで,青枯病およびトマト萎凋病に対する発病抑制効果が期待できる。
Bacterial wilt caused by Ralstonia solanacearum and fusarium wilt caused by Fusarium oxysporum f. sp. lycopersici induce damage during the production of tomato. In this study, we investigated the control effect of these diseases by using pepino (Solanum muricatum Aiton) as a rootstock. In inoculation test of R. solanacearum of bacterial groupⅠ-Ⅴ and F. oxysporum f. sp. lycopersici races 1-3, own-rooted tomato ‘Ogata-fukuju’ was highly susceptible to all of the strains, whereas own-rooted pepino ‘Gold No.1’ and tomato ‘Ogatafukuju’ grafted on pepino ‘Gold No.1’ were completely resistant to all of the strains. Our results indicate that pepino ‘Gold No.1’ is resistant to the R. solanacearum bacterial groups and F. oxysporum f. sp. lycopersici races 1-3, and application of pepino as a rootstock can be an effective method for control of bacterial wilt and wilt diseases.
