Study On The Allelopathy Of The Iris Lactea-Pall.var.chinensis Koidz

The paper dealt with the pilot study about the allelopathy of the Iris lactea Pall. var.chinensis Koidz water steep. Mainly come to launch from three respects, it is the receptor toselect the radish , alfalfa , cucumber seed for use at first, take allelopathy function surveywhether the soak have. Regard month as unit secondly, to test the allelopathy intension of theIris. Finally, to be determined by the biochemical index of receptor the plant seedling.Experimental result indicate: the treatment A of the Iris root soak don't have influence tothree see sprout ,the C have conspicuous effects on seed of the cucumber only, then only thetreatment B have influence and achieve to prominent competence to the sprouting of the seed.Then the leaf soak of the Iris ,except the C have no influence to the seed sprout of the radishand alfalfa, other each treatment have influence and achieve to prominent competence to thethree kinds of seeds. Seedling grow situation is to be the same, the each density of the leafinhibit and reach the prominent level to the growth of root of cucumber, radish, alfalfa,particularly the A and B act the most prominent in inhibition of the alfalfa. The treatment Band C of the root soak inhibit to root growth of radish , alfalfa ,cucumber, from appeardifference to be competence prominent, and it is most obvious to alfalfa and cucumber to dealwith B. Summarize, the Iris have allelopathy , take sense function, with try on plant differentdifferent power of function, handle density to be different to take sense to be intensitydifferent at the same time, than to take sense to be intensity loud underground biologicalquantity living beings amount on the ground.Through to slat the final sprouting rate of the receptor plant seed ,can find out the finalsprouting rate in alfalfa, the three month soak have no prominent influence . according to theradish seed of the receptor ,the August soaks carries a largest influence on final sprouting rateof it , and the number of the treatment B is the most low, indicate that the Iris allelopathyfunction different as time is different , its strongest function appears in August.Through the measure of the protein content of the plant seedling, peroxidese (POD),catalase (CAT), superoxide dismutase (SOD) we can see ,the Iris soaks carries the differentinfluence to the biochemical index of the seedling of the alfalfa and the Chloris virgata Swartz.Among them, the Iris soak 's three density treatment have influence to the four biochemicalindexes of seedling of the alfalfa, have been shown as reduced the protein content (dealt withA , B ), has reduced the energy of POD (deal with A , B , C ) , CAT (deal with B , C ) , SOD(deal with B , C ) but influence is not very prominent . then the influence of the three densitytreatment of the Iris soak to the Chloris virgata Swartz.'s four biochemical influence of indexof seedling show as increased the protein content (deals with A , C ) ,improve the energy ofPOD (deal with B , C ) , CAT vigor of SOD (punish A , B , C ) , and the influence is veryprominent. So, the Iris soak have faintness allelopathy to the alfalfa show as inhibiting effect,then to the Chloris virgata Swartz., the soak have more strong function show as inhibit andpromote as well as.The order of the article selects the plant of the Iris--Iris lactea Pall. var. chinensisKoidz as research object, studies its allelopathy potential ,is that provides the basic theory forthe study of the interspecific competition and the population succession.
