From: Effect of stem bending and soil moisture on the incidence of resin pockets in radiata pine
The number of Type 1 resin pockets formed per tree at radial positions within the growth rings (a) during the pre-treatment years (2003–2007) and (b) during the treatment year (2007–2008), for the stem bending and control treatments. Symbols: Light blue circle with line Control, Green Square with line Spring, Orange triangle with line Summer - water stressed, Dark Blue down triangle with line Summer - released from water stress.
