Effect of root pinching on growth patterns of blue oak (Quercus douglasii H. & A.) seedlings



Effect of root pinching on growth patterns of blue oak (Quercus douglasii H. & A.) seedlings



Phyton Horn 34(1): 109-118



A study was made of the effects of root pinching (i.e. cutting off the tip of the acorn radicle) on growth patterns of blue oak (Quercus douglasii) seedlings. The immediate responses of the seedlings were: (a) increase of root branches in the upper 10 cm of the soil profile; (b) increase of root dry mass in the upper 10 cm of the soil profile; and (c) faster root growth rate. Total root length and dry mass were not affected.
