Methods and accuracy of assessing conifer advance growth when marking out coupes

, : Methods and accuracy of assessing conifer advance growth when marking out coupes. Sborn. Trud. Povolzsk. Lesotehn. Inst, 58, 21-30

If deviations of not more than 10% from the mean are considered acceptable, the method recommended is to count the advance growth on plots 2 X 5 m. spaced 25 m. apart along sight-lines.

During microRNA (miRNA) biogenesis, two endonucleolytic reactions convert stem-loop-structured precursors into mature miRNAs. These processing steps can be posttranscriptionally regulated by RNA-binding proteins (RBPs). Here, we have used a prote...
