\"SivaSivo plesen povzro\u010da gliva Botrytis cinerea<\/em>, ki zelo pogosto napada rastline. Prepoznamo jo po sivkasti kosmati rasti, ki prekriva oku\u017eeno rastlinsko tkivo. Gliva lahko napade \u0161tevilne rastline, pri \u010demer so najbolj izpostavljene tiste, ki jih gojimo v steklenjakih oz. prostorih z visoko zra\u010dno vlago. Pogosto jo najdemo tudi na plodovih, ki vsebujejo veliko vode kot so npr. jagode.<\/p>\n

Siva plesen oku\u017ei rastline preko ran, pri \u010demer najla\u017eje oku\u017ei rastline, ki so izpostavljene stresu. Najpogosteje jo najdemo na jablanah, vinski trti, jagodah, robidah, malinah<\/a>, fi\u017eolu, kumarah, bu\u010dkah<\/a>, solati<\/a> in paradi\u017eniku<\/a>. V zaprtih in vla\u017enih prostorih lahko oku\u017ei tudi razli\u010dne okrasne rastline kot so npr. ciklame, krizanteme, pelargonije, jegli\u010de in pravzaprav ve\u010dino okrasnih rastlin.<\/p>\n

Simptomi sive plesni<\/h2>\n

Simptomi oku\u017ebe s sivo plesnijo se ka\u017eejo kot siva prevleka, ki je v suhih razmerah lahko omejena na majhen del rastline, vendar se v vla\u017enem vremenu hitro raz\u0161iri. Oku\u017eeni deli rastline se posu\u0161ijo in navadno propadejo. Pri nekaterih rastlinah lahko siva plesen povzro\u010di tudi odmiranje celih poganjkov. Oku\u017eba jagod in grozdja pa navadno vodi v razvoj gnilobe, ki uni\u010di plodove.<\/p>\n

Biologija<\/h2>\n

Gliva B. cinerea<\/em> je saprofit (prehranjuje se z mrtvim rastlinskim materialom), vendar lahko pod dolo\u010denimi pogoji oku\u017ei tudi \u017eivo rastlinsko tkivo. Njene spore do prisotne povsod in se razna\u0161ajo z vetrom. Gliva prezimi na mrtvem rastlinskem materialu, na katerem tvori sklerocije. Slednji kalijo in sprostijo spolne spore, ki jih razna\u0161a veter. Precej \u0161tevil\u010dnej\u0161e pa so nespolne spore (konidiji), ki se spro\u0161\u010dajo iz zna\u010dilnih sivih kosmatih plevlek.<\/p>\n

Poleg sive plesni obstajajo \u0161e nekatere sorodne vrste, ki prav tako povzro\u010dajo bolezni vrtnih rastlin: vrsta B. galanthina<\/em> oku\u017euje predvsem zvon\u010dke<\/a>, B. peoniae<\/em> najdemo na potonikah, B. fabae<\/em> pa na bobu.<\/p>\n

Zatiranje<\/h2>\n

Za prepre\u010devanje razvoja sive plesni je zelo pomembna ustrezna higiena. Slednja je \u0161e posebej pomembna pri vzgoji rastlina v rastlinjakih. V rastlinjakih redno odstranjujte odmrle liste, poganjke in cvetove. Pazite tudi na ustrezno zra\u010denje, ki bo ustrezno zni\u017ealo vlago in mo\u017enost razvoja sive plesni.<\/p>\n","protected":false},"excerpt":{"rendered":"
