Analysis test method of allelopathy of plant organ water-soluble extract

The present invention relates to analytical test methods EXTRACTS soluble plant organ function, the method comprising when the valve is closed, is added to the glass bottle plant organ, quartz sand was added in plant cultivation dish, cultivated plant seedlings, seedlings survived until after , the valve is opened, so that the liquid nutrient of the plant cultivation dish through the communication pipe into the bottom of a glass bottle, a nutrient solution containing a water soluble extract of plant organ into the bottom of the glass tube in communication, under the action returns to the gas stream dish inside the plant cultivation, plant height was measured when the plant cultivation dish of flowering in plants, leaf area, biomass, photosynthetic rate, root activity, SOD, POD, CAT and of MDA, when measuring plant biomass and maturity yield, then compared with corresponding indicators control plants, allelopathy available water soluble extract of plant organs of plants. The present invention adopts a method to study the process of a water soluble extract of plant organ collection and integration of allelopathic effects, thereby improving the work efficiency, reduce the workload.
