Techniques in environmental physiology of oil palm 3:evaporation
Penggunaan kaedah ymg murah dan mudahalih bagi menyukat penyejatan air dari permukaan tanah dan perpeluhan dari pelepah dihuraikan. Contoh sukatan diberi bagi menunjukkan bagaimana penyejatan berubah bergantung kepada sinaran suria, waktu dan kedudukan daun dalam rimbunan dahan.
Adaptation to Light Environment by Leaves of Oil Palm (Elaeis guineensis)
Pertukaran gas daun dan sifat morfologi bagi pokok sawit muda yang tumbuh di kawasan yang terdedah kepada matahari dan kawasan yang ternaung dibandingkan. Daun-daun pokok yang tumbuh di tempat naung didapati mempunyai luas permukaan yang lebih berbanding daun di tempat terdedah, tetapi mempunyai berat kering per unit yang lebih rendah. Ketumpatan stomata, konduktans maksimum, kecekapan […]
Water defisit and irrigation in oil palm: a review of recent studies and findings
The role of water deficit in oil palm is discussed in this paper. Factors such as evapotranspiration, relative humidity and vapour pressure deficit affect the carbon assimilation process and oil palm growth in general. Various irrigation techniques have been tried to overcome this water deficit and some of the results are discussed. Abstrak: Peranan defisit […]
Some observations on the effects of high water tables and flooding on oil palm, and a preliminary model of oil palm water balance and use in the presence of a high water table
High water tables, indicating impeded drainage, are known to reduce yields although quantitative information is somewhat sparse. However, complete flooding can cause death of young palms as well as reduce the yield of older ones. Uncertainties exist as to how effectively oil palm roots function when in saturated soil, both in terms of absorbing water, […]
