| description | The effect of inoculation on containerized pine and spruce seedlings in a nursery with two
ectomycorrhizal fungi was investigated in regard to the development of mycorrhiza and plant growth. The fungi were Elaphomyces muricatus and Elaphomyces granulates and the inoculated seedlings were compared to an uninoculated control. These seedlings were all fertilized with arginine.
Five mycorrhiza species were found after DNA sequencing of the mycorrhizal root tips with different found morphotypes on seedlings from all treatments. Thelephora terrestris was the type which had the greatest distribution on pine seedlings and Tylospora asterophora was found at big extent on spruce seedlings. The inoculated species was not found, if it was due to the species hadn't colonized the roots or if the DNA sequencing failed we can only speculate about. Two morphotypes were found on inoculated seedlings that were not found on the other seedlings.
Besides the inoculations, another study was done to compare two fertilizers which contained different nitrogen sources: ArGrow®complete with the aminoacid arginine and Wallco® with ammonium and nitrate.
The inoculated pine seedlings had lower number of mycorrhizal infected short roots than the control and the E. muricatus seedlings had both less shoot length and less stembase diameter than the control.
The pine seedlings fertilized with Wallco both had a lower number of tips and a lower share of mycorrhiza than the plants fertilized with arginine.
The spruce plants didn't show any differences between treatments. |

Mykorrhizaförekomst och tillväxt hos täckrotsplantor av tall och gran undersöktes efter inokulering med sporer från två mykorrhizabildande tryffel arter: Grynig hjorttryffel,(Elaphomyces granulatus) och marmorerad hjorttryffel, (Elaphomyces muricatus) samt jämfördes med en oinokulerad kontroll. Vid DNA sekvenseringen av mykorrhizainfekterade rotspetsar från samtliga behandlingar hittades totalt 5 olika mykorrhizaarter. Thelephora terrestris var den mest frekvent förekommande arten på tall och Tylospora asterophora fanns i stor omfattning på gran. Dock hittades inte de inokulerade arterna. Om det beror på att de inte fanns där eller att sekvenseringen misslyckades gick inte att fastställa. Dock så hittades 2 morfotyper på de inokulerade plantorna som inte fanns på de övriga plantorna. De inokulerade tallplantorna hade mindre antal mykorrhizainfekterade rotspetsar än kontrollen och plantorna inokulerade med marmorerad hjorttryffel hade både kortare skottlängd samt klenare stambasdiameter än kontrollen. En jämförelse gjordes även mellan plantor som gödslats med två olika gödselmedel, ett innehållande aminosyran arginin – arGrow®complete och ett annat kommersiellt gödselmedel innehållande ammonium och nitrat -Wallco®. De ammonium och nitrat gödslade tallplantorna hade både mindre antal rotspetsar och mindre andel mykorrhiza men längre skottlängd än argininplantorna. Granplantorna visade inga skillnader mellan behandlingarna. 2009-03-11 Other NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/12943/1/edvardsson_L_171117.pdf Edvardsson, Lisa, 2009.
