Xasaasiyadda waxaa badanaa lagu qeexaa mid kasta oo toos ah ama mid aan toos ahayn, saamayn togan ama taban mid ka mid ah noocyada dhirta kale iyada oo loo marayo wax soo saarka iyo sii daayo ee xeryahooda kiimikada deegaanka.1]. Dhirtu waxay ku sii daayaan allelochemicals jawiga ku hareeraysan iyo ciidda iyada oo loo marayo isbedbeddel, caleenta caleenta, dheecaanka xididka, iyo burburka haraaga.2]. Sida hal koox oo ah allelochemicals muhiimka ah, qaybaha isbedbeddelaya waxay u galaan hawada iyo ciidda siyaabo isku mid ah: dhirtu waxay si toos ah u sii daayaan kacsanaanta jawiga [3]; Biyaha roobka ayaa ku luqluqa qaybahan (sida monoterpenes) oo ka soo baxa qaab-dhismeedka qarsoodiga ah ee caleenta iyo dhumucda dusha sare, taas oo siinaysa suurtogalnimada qaybo isbeddelaya ciidda.4]; Xididdada dhirta waxay ku sii dayn karaan carrada qallafsan ee herbivore-ku-abuuray iyo kuwa cudur-sidaha keena.5]; Qaybahan ku jira qashinka dhirta ayaa sidoo kale lagu sii daayaa ciidda ku xeeran [6]. Waqtigan xaadirka ah, saliidaha kacsan ayaa si isa soo taraysa loo sahamiyay isticmaalka haramaha iyo xakamaynta cayayaanka [7,8,9,10,11]. Waxaa lagu ogaadaa inay u dhaqmaan iyagoo ku faafaya xaaladdooda gaasaska hawada iyo iyagoo u beddelaya gobollo kale oo soo galaya ama ciidda ku jira.3,12], isagoo door muhiim ah ka ciyaaraya joojinta koritaanka dhirta iyadoo la adeegsanayo isdhexgalka noocyada kala duwan iyo beddelidda bulshada dhirta dalagga-weed [13]. Daraasado dhowr ah ayaa soo jeedinaya in allelopathy ay fududeyn karto sameynta xukunka noocyada dhirta ee nidaamka deegaanka dabiiciga ah [14,15,16]. Sidaa darteed, noocyada dhirta ugu badan ayaa lagu bartilmaameedsan karaa ilaha suurtagalka ah ee allelochemicals.
Sanadihii la soo dhaafay, saamaynta allelopatitic iyo allelochemicals ayaa si tartiib tartiib ah u helay feejignaan badan oo ka yimid cilmi-baarayaasha ujeeddada lagu ogaanayo beddelka habboon ee herbicides-ka17,18,19,20]. Si loo yareeyo khasaaraha beeraha, herbicides si isa soo taraysa ayaa loo isticmaalaa si loo xakameeyo koritaanka haramaha. Si kastaba ha ahaatee, adeegsiga aan loo meel dayin ee dawooyinka loo yaqaan 'synthetic herbicides' ayaa gacan ka geystay kororka dhibaatooyinka iska caabinta haramaha, nabaad-guurka tartiib-tartiibka ah ee ciidda, iyo khataraha caafimaadka aadanaha.21]. Xeryahooda allelopathic ee dabiiciga ah ee ka soo baxa dhirta ayaa bixin kara karti aad u weyn oo loogu talagalay horumarinta herbicides cusub, ama sida xeryahooda rasaasta ee lagu aqoonsanayo herbicides cusub, dabeecadda ka soo jeeda.17,22]. Amomum villosum Lour. waa geedo daaqsimeed sanadle ah oo ka tirsan qoyska sinjibiisha, oo koraysa ilaa 1.2-3.0 m oo hooska geedaha. Waxay si ballaaran ugu baahsan tahay Koonfurta Shiinaha, Thailand, Vietnam, Laos, Cambodia, iyo gobollada kale ee Koonfur-bari Aasiya. Miraha qallalan ee A. villosum waa nooc ka mid ah xawaashka caadiga ah sababtoo ah dhadhan soo jiidasho leh.23] waxayna u taagan tahay dawo dhaqameed caan ka ah Shiinaha, taas oo si weyn loogu isticmaalo daaweynta cudurrada caloosha iyo mindhicirka. Daraasado dhowr ah ayaa sheegay in saliidaha kacsan ee hodanka ku ah A. villosum ay yihiin qaybaha ugu muhiimsan ee daawooyinka iyo maaddooyinka caraf udgoon.24,25,26,27]. Cilmi-baadhayaashu waxay ogaadeen in saliidaha lagama maarmaanka ah ee A. villosum ay muujiyaan sunta xiriirka ka dhanka ah cayayaanka Tribolium castaneum (Herbst) iyo Lasioderma serricorne (Fabricius), iyo sunta fumigant xoog leh oo ka dhan ah T. castaneum.28]. Isla mar ahaantaana, A. villosum waxay saameyn xun ku leedahay kala duwanaanshaha dhirta, biomass, qashinka iyo nafaqooyinka ciidda ee kaymaha roobka aasaasiga ah [29]. Si kastaba ha ahaatee, doorka deegaanka ee saliidda kacsan iyo xeryahooda allelopathic weli lama garanayo. Marka la eego daraasadihii hore ee lagu sameeyay walxaha kiimikada ee A. villosum saliidaha lagama maarmaanka ah [30,31,32], Ujeedadayadu waa in aan baarno bal in A. villosum ay sii deyso xayndaabyo leh saameynaha allelopathic ee hawada iyo ciidda si ay u caawiso in la dhiso awooddeeda. Sidaa darteed, waxa aanu qorshaynaynaa in aanu: (i) lafaguro oo is barbar dhigo qaybaha kiimikaad ee saliidaha kacsan ee xubnaha kala duwan ee A. villosum; (ii) waxay qiimeeyaan allelopathy ee saliidaha kacsan ee laga soo saaray iyo xeryahooda kacsan ee A. villosum, ka dibna la aqoonsado kiimikooyinka lahaa saamaynta allelopathic ee Lactuca sativa L. iyo Lolium perenne L.; iyo (iii) si hordhac ah u sahamiyaan saamaynta saliidaha A. villosum ee kala duwanaanshaha iyo qaab dhismeedka bulshada ee noolaha yar yar ee ciidda.
