摘要: 〝青莢〞長豇豆以蛭石2號及Agro-Lig進行固體滲調,滲調種子於25℃下發芽,以蛭石處理者,處理水量會影響豇豆種子之發芽率;以Agro-Lig處理者,處理水量顯著影響種子之發芽率,介質大小及水量現著影響平均發芽天數。以種子:蛭石2號:0.1%NaOCl之重量比為15:15:25進行固體滲調,處理3天,滲調種子於15℃、25℃及35℃之平均發芽天數被縮短,於15℃之發芽率被提高,且於田間出土率及出土速度被促進。滲調豇豆種子於25℃下發芽,於第一階段之吸水速度加快第二階段則不影響,滲調期間種子所釋放的二氧化碳量依加水量增加而增加。滲調豇豆種子之導電度值隨滲調時水量增加而逐漸減少,以25ml水量處理者顯著較未處理者低20μA/seed/4ml。
‘Green-pod' asparagus bean seeds were primed via solid matrix priming using the vermiculite #2 and Agro-Lig as the solid matrix. The germination percentages of seeds were significantly affected by amount of water in the media during seed priming. The seeds were primed by the weight ratio of seed: vermiculite #2: 0.1%NaOCl=15:15:25 for three days that could short the mean germination days at 15℃, 25℃, and 35℃, as well as increased the germination percentage at 15℃. These primed seeds significantly had high emergence percentage and rate in the field. When the seeds germinated at 25℃, the inhibition rate of phaseⅠof the primed seeds was faster than those of the non-primed seeds. When increasing the water amount in the media during seed priming, the released CO2 from the priming seeds was increased and the value of the conductivity of the primed seeds was decreased. The conductivity value of the seeds primed with 25ml of water was lower 20µA/seed/4ml than that of non-primed seeds.
