摘要: The studies were to seek that effect of bare root and dark Simulated transport on physiology and morphology of Colmanara Wildcat. The results showed that ethylene production of Colmanara Wildcat with bare root substantially increase in seventh day in simulated dark transport than that of the control. After simulated dark transport for 5, 7, 10 days that caused the root activity descended, and along with the days after dark treatment, the activity of roots more low. The roots lost activity and dry resulted in loss water, which led Colmanara Wildcat root activity to decrease into 1.01 O.D./g and 0.92 O.D./g and 0.89 O.D./g from original 1.56 O.D./g. The total soulable sugar content of pseudobulb was increase following days past, and the starch content of preudobulb was increase in fifth day then decline in seventh day during dark treatment. 1-aminocyclopropane-1carboxylic acid (ACC) was high in seventh day than that of the control, and 1-aminocyclopropane-1carboxylic acid oxidase (ACO) activity was high, too. The results indicate that dark stress and loss water stress had large effect on bare rooted Colmanara Wildcat with quality or senescence of many examined.
本試驗主要探討文心蘭野貓品種Colmanara Wildcat 裸根黑暗模擬貯運不同天數後對生理及形態之影響。文心蘭野貓Colmanara Wildcat經裸根模擬貯運0、5、7及10天,結果顯示,於第7天時乙烯生成量相較於對照組高出甚多,植株根部會因失水導致活力的喪失及乾癟,且根部活力隨天數的增加而下降,經模擬貯運5、7及10天之文心蘭根部活性會由原本的1.56 O.D./g分別降低為1.01 O.D./g、0.92 O.D./g及0.89 O.D./g。模擬貯運過程中假球莖全可溶性糖含量會依天數增加而增加,於第10天時為44.93%DW。而假球莖中澱粉含量則依天數增加而減少。分析ACC生成及ACO活性在模擬貯運第7天時皆高於對照組。試驗中之結果顯示黑暗模擬貯運及缺水逆境會對文心蘭裸根植株的品質及老化上造成莫大的影響。
