Abstract: By studying the five kinds of trace elements on Prunus×Cistena Pissardii leaves chlorophyll a concentration variation of the impact of research, with a view to the development a new purple leaf dwarf cherry liquid special vase to provide theoretical basis for. With growth of 15 leaves of Prunus×Cistena Pissardii new branches as experimental material, containing Mn, Cu, B, Zn, Mo five elements in high Medium and low concentrations of nutrient solution as the reagent, with water as the control culture, repeated three times, measured the1,3,5,7-day chlorophyll a content. Experimental results show that, Mn element would make the chlorophyll a always tended to increase in whole time,other four kinds of elements to show first elevated and then slightly lower, Mn, Cu elements are beneficial to production of chlorophyll a, B, Zn, Mo will lower the chlorophyll a content; The 1,3 days after treatment, Mn, Cu elements chlorophyll a concentration higher than the control, B, Zn, Mo chlorophyll a concentration lower than the control; On the seven days, The results of variance analysis showed that three concentration of Mn treatment was significantly higher than the control, the other four kinds of elements and no significant difference between controls. After comprehensive comparison concludes: The better Prunus×Cistena Pissardii vase liquid formulations in order to contain low concentrations of Mn, Cu elements, higher concentration of B, Zn, Mo elements are better.
