Phlebiopsis gigantea attīstība maza diametra skuju koku celmos

2016

Lai novērtētu P. gigantea micēlija attīstību skuju koku celmos sastāva kopšanas cirtēs, četrās audzēs Vidusdaugavas mežsaimniecībā tika ierīkots eksperiments, kurā ar „Rotstop” un divu Latvijas P. gigantea izolātu konīdijsporu suspensijām apstrādāja maza diametra (3 – 12 cm) parasto egļu un parasto priežu celmus. Pēc gada tika ievākti koksnes paraugi un analizēta P. gigantea attīstība celmos. P. gigantea izolāti labāk attīstījās maza diametra priežu celmos nekā egļu celmos. Dabiskā P. gigantea infekcija konstatēta 20% maza diametra priežu celmu. Salīdzinot „Rotstop” ar vietējiem izolātiem, Latvijas izolāta PG137 attīstības biežums priežu celmos būtiski neatšķīrās un P. gigantea micēlijs sas…
