Abstract

 An    experiment     was    conducted     to    investigate    the    physiological     responses    and     growth    of    waterlogged     oil    palm   (Elaeis    guineensis    cv.   Suratthanee  2)   seedlings   at   Krabi    Oil    Palm Research    Centre,    Klong     Thom    district,    Krabi   province    during    June-November   2008.    Thirty    oil   palm    seedlings    were    grown    in  0.57 m<sup>3</sup>   cement    pot    under     natural     conditions.    The    experiment   was    arranged      in   CRD    with 5    treatments.    Twelve    month-old   oil   palm    seedlings   were   subjected    to   continuous    waterlogging    for   0  (non-waterlogged   seedlings),   15,  30,   60   and   90   days,    and    then   drained.   Six seedlings    were   used    for   each    waterlogging   treatment. It   was    found    that    the   effects    of   60   and    90    days   of    waterlogging     had    lower    stomatal    conductance,    leaf    water    potential,    total    chlorophyll     content    and     net    photosynthesis   than    those   of    non-waterlogged    seedlings.    Moreover,    growth   rate   (height, number   of    petiole,    cross-section    area     of    petiole    and    leaf    area) and    both   fresh     and   dry    weights    of   oil    palm    seedlings    were   also    markedly    decreased     as   a    result    of    waterlogged     condition  for  60   and   90    days.     Therefore,     this     study      was     indicated    that    long    periods   (over    60    days)   of    waterlogging     caused    a   reduction    in    growth    and    biomass     allocation    of    oil    palm     seedlings   which    ultimately    negative     affected    oil    palm    productivity.
