The effect of trans-2-hexenal and trans-2-nonenal on the mycelium growth of Phoma narcissi
in vitro
From Research Institute of Pomology and Floriculture
in Skierniewice
Abstract. The effect of trans-2-hexenal and trans-2-nonenal on the mycelium growth of Phoma narcissi on PDA medium was investigated. Both aldehydes strongly inhibited the mycelium growth of P. narcissi when applied to PDA medium or applied as volatiles; greater inhibitory effect was observed when they were applied as volatiles. The inhibitory effect on the mycelium growth of P. narcissi was greater of trans-2-nonenal than trans-2-hexenal.
Key words:

Wp³yw trans-2-heksenalu i trans-2-nonenalu na wzrost grzybni Phoma narcissi in vitro
Streszczenie
Badano wp³yw trans-2-heksenalu i trans-2-nonenalu na wzrost grzybni Phoma narcissi na po¿ywce PDA. Obydwa aldehydy silnie hamowa³y wzrost grzybni P. narcissi, kiedy dodawano je do po¿ywki lub podawano w postaci lotnej; wiêksze inhibitorowe dzia³anie wywiera³o zastosowanie tych aldehydów w postaci lotnej. Hamuj¹cy wp³yw trans-2-nonenalu na wzrost grzybni P. narcissi by³ wiêkszy ni¿ trans-2-heksenalu.
