Treatment of Scots pine seeds by biological preparations as a way of improving the planting material quality in forest nurseries of Krasnoyarsk Krai
The effectiveness of treating Scots pine Pinus sylvestris L. seeds by biological preparations based on Trichoderma Pers. fungi to improve the quality of the seedlings was tested in small-plot experiments and by sowing on the industrial scale in two forest nurseries of Krasnoyarsk Krai. It was found...

The effectiveness of treating Scots pine Pinus sylvestris L. seeds by biological preparations based on Trichoderma Pers. fungi to improve the quality of the seedlings was tested in small-plot experiments and by sowing on the industrial scale in two forest nurseries of Krasnoyarsk Krai. It was found that in the small-plot experiments, the treatment of pine seeds with biological preparations improved the safety of seedlings by 12.3 times (T. harzianum) and 16.4 times (T. lignorum (Tode) Harz + T. harzianum) as compared to the control.
