description

Lai novērtētu maza diametra skujkoku celmu uzņēmību pret H. annosum s.l. bazīdijsporu infekciju dažādos gada laikos, apsekotas 7 audzes Vidusdaugavas mežsaimniecībā, kurās 2013. gada martā un jūlijā veiktas sastāva kopšanas cirtes. Celmu ripas tika analizētas pēc 3 – 5 mēnešiem. Pēc tam tika novērtēta H. annosum s.l. un P. gigantea sastopamība maza diametra priežu un egļu celmos. Egļu celmi bija uzņēmīgāki pret H. annosum s.l. infekciju, nekā priežu celmi, savukārt priežu celmi bija uzņēmīgāki pret P. gigantea infekciju. Novērota statistiski būtiska lineāri pozitīva korelācija starp ar H. annosum s.l. inficēto egļu celmu īpatsvaru un diametru. Turpmākajā darbā paredzēts analizēt H. annosum s.l. un P. gigantea infekcijas attīstību maza diametra skujkoku celmos rudens un ziemas mēnešos.
