Study on Effects of Coleus Trees Branches of Material of Osmotic in Lasting Low Temperature
Abstract：To study in continues -20 ℃ low temperature stress, branches of trees within the garden in vitro permeability changes of substance, It is to provide a theoretical basis for the deep sleep physiological changes in vitro the branches and determine the cold hardiness of trees. Experiment with in the deep dormancy of Prunus× Cistena Pissardii, Cotinus coggygria ‘ Atropurpureus’, Acer Palmatum, Acer truncatum Bunge for the tested material, branches in water-in vitro conditions, -20 ℃ low--temperature stress to provide use the refrigerator, repeat 3 times. The results showed that： soluble sugar content showing a higher changes in four kinds of coleus trees branches and respectively increased rate as 93. 56%, 162.45%, 114. 95%, 5Z. 19%; in Cotinus coggygria ‘ Atropurpureus’ branches, soluble protein changes expression as first increased and then decreased and other three species has been showed increased changes and when the test was end significantly higher than the first 3 days; the free proline was no significant difference in Prunus× Cistena Pissardii and Acer Palmatum branches and the 15th days was significantly higher than the 3th days. Comprehensive analysis that colorful tree branches away from the body under cold stress at --20 ℃ still has some physical activity and cold resistance Prunus× Cistena Pissardii slightly higher than the other three species.
