]]>Dexian He David B. South 4200764Longitudinal sections revealed that radicles of laboratory-grown slash (Pinus elliottii Engelm.) and loblolly (Pinus taeda L.) pine and lateral roots of naturally-grown and container-grown loblolly pine developed a rootcap that was 3-8 cell layers wide around the root proper at the level of the quiescent center and 8-32 cell layers from the quiescent center to the distal tip. Rootcap cells contained amyloplasts which were located mainly in the rootcap center and central columellar cells of the rootcap. Large amyloplasts were located in and around the rootcap center while small amyloplasts were found in other columellar cells. Amyloplast number per rootcap cell varied with pine species and with how seedlings were grown. There were fewer amyloplasts in radicles than in lateral roots. The spatial distribution of amyloplasts was similar between radicles and lateral roots and they were not found exclusively on the bottom of rootcap cells.]]>Barlow, P.W.,19742511371146Esau, K.,19772nd Edn.,pp: 550pp: 550He, D.X.,20032003Hensel, W.,1986Lepidium sativum L.).]]>169293303Li, Y.H.,1984pp: 417pp: 417Moore, R. and C.E.
