ナス台木'トレロ'種子のポリエチレングリコール処理と低温処理による発芽促進(繁殖・育苗)  [in Japanese] Polyethylene Glycol Processing and Low Temperature Processing Promote Seed Germination of Rootstock 'Torero' for Eggplant(Propagation & Transplant Production)  [in Japanese]

'トレロ'種子の25℃恒温条件での発芽促進には,PEG300g/literにGA_3100mg/literを添加した溶液で15日間のプライミング処理が効果的であった.発芽促進効果は,5℃の低温貯蔵またはデシケータ保存で少なくとも30日程度実用レベルで維持できた.1998年産種子はPEG+GA_3処理だけでは十分な発芽促進効果が得られなかったが,PEG+GA_3処理前に低温処理を5℃で21〜31日間実施すると著しく発芽促進効果が高まった.

Since the seeds of rootstock 'Torero' for eggplant have a poor germination rate, the effects of priming processing using some promoting chemicals, such as polyethylene glycol solution, were studied. When the seeds were treated with a combination of GA_3 100 mg/liter to PEG 300 g/1iter for about 15 days, germination was effectively promoted. Furthermore, the practical effect of treatment persisted for at least 30 days when dried seeds were stored at 5℃ or low humidity. Although the seeds harvested in 1998 did not show exceptionally germination improved by chemical treatment only, the additional treatment of the low temperature procedure for 21 to 31 days before the chemical treatment remarkably improved germination.
