Abstract: Coconut palm is of great social and economic importance for millions of people in the tropics and subtropics. Drought is one of the main environmental factors that limit coconut productivity. In this review, physiological and morphological data are presented in an integrated perspective to provide a holistic view of the behavior of coconut trees facing water deficit under both field and controlled conditions. Great capacity to produce homorhizic roots capable of searching continuously for water and nutrients a… Show more

“…The few ecophysiology studies conducted to investigate palms describe tolerant species to drought stress Gomes and Prado 2007;Suresh et al 2012;Medeiros et al 2015). There are many palm species with economic importance, such as Elaeis guineensis or oil palm (Suresh et al 2012), Cocos nucifera or coconut palm (Gomes and Prado 2007), Bactris gasipaes or peach palm and Acrocomia aculeata or macaw palm (Pires et al 2013), most of them found in tropical rain forests.…”

“…The physio-biochemical responses of oil palm seedlings under either mannitol or PEG-induced isoosmotic stress have not been reported previously. In the Arecaceae family, ecophysiological expression in coconut palms, including membrane lipid composition (Repellin et al, 1997), photosynthetic ability and growth performance under water deficit stress, using PEG solution, has been investigated (Gomes and Prado, 2007;Gomes et al, 2008). Also, we have investigated the physio-biochemical responses of oil palm seedlings grown under PEG-induced water deficit (Cha-um et al, 2010b).…”

“…Thus, increasing root absorption capacity per surface unit to favor the partitioning of assimilates towards this organ is a tolerance response to water deficit (Ryser, 2006;Polanía et al, 2009), mainly in oil palm ). However, under severe water deficit conditions, the 'U1937' hybrid decreased its overall water potential, as an active response to the accumulation of reducing and total sugars in leaf cells (decrease in osmotic potential), which allowed the plants to maintain their flow of water through the roots and reduce its loss through the stomatal chamber, a response that some authors consider as an indicator of growth or survival (tolerance) to water deficit (Handa et al, 1983;Gomes and Prado, 2007;López et al, 2009). This type of osmotic adjustment under water deficit conditions has been reported in leaves and in other organs of sorghum, rice, potatoes, corn, wheat (Silva et al, 2007), pine (López et al, 2009), and oil palm .…”

“…Finally, taking into account that tolerance to water deficit certainly integrates several traits such as photosynthetic rate, distribution of assimilates among vegetative (roots and bulb reserves) and reproductive organs (bunches), stomatal regulation, rigidity of cellular membrane structures (lipids and proteins), and osmotic adjustment (Cornaire et al, 1994;Silva et al, 2007;Jaleel et al, 2009), these results allow establishing two genotype/environment tolerance relationships that do not rule out hybrids, but place them according to the soil water potential and their best ecophysiological response in terms of high photosynthetic rates, low leaf respiration rate, water potential adjustment, and water use efficiency, as Gomes and Prado (2007) did when working with coconut (Cocus nucifera). Therefore, the relationships are: adequate soil moisture conditions (field capacity) with a tolerance of 'U1859'>'U1937'='U1914'>'U1273'; and moderate and severe water deficit conditions with a tolerance of 'U1937'>'U1914' >'U1859'>'U1273'.…”
