The date palm bunch fading disorder/disease is one of the greatest challenges faced by date palm growers. In the present study, the effect of appropriate orchard management on some qualitative and quantitative features of date palm bunch was studied. For this purpose, two orchards of cv ‘Kabkab’ with a history of previous incidence were selected in two districts of Bushehr province; Tangestan a...
The propagation of palms for agricultural and ornamental purposes is accomplished typically by seeds. The few exceptions are certain cultivars of Phoenix dactylifera and some ornamental palms such as Rhapis spp., which propagate by vegetative (division) and tissue culture. Because of slow, irregular germination in most species, seed propagation may be a challenge. New palm species are being int...
G lobally, vegetable oils are harvested from a handful of oil crops at an annual rate exceeding 100 million tons (1). Most oils are used for human or animal consumption, although a minor fraction is derivatized to oleochemicals. More recently, an increasing amount of vegetable oil is being diverted to the production of biodiesel [i.e., fatty acid (FA) methylesters], and is an attractive feedsto...
Background: In Algeria, date palm is currently confronted to the Bayoud disease. Biotechnological tools such as protoplasts fusion can appear as an alternative to ensure rapid multiplication and improvement of this species. Objectives: Callogenesis induction in protoplasts isolated from embryogenic callus of three date palm cultivars. Materials and Methods: Some factors influencing the isolatio...
The agouti (Dasyprocta punctata) meticulously defleshes Astrocaryum standleyanum palm seeds before scatter hoarding. On Barro Colorado Island, Panama, we experimentally tested three hypotheses on how this behaviour could reduce seed predation to the mutual benefit of the tree and the rodent. The first and established hypothesis – that defleshing reduces seed predation by bruchid beetles by inte...
Hydroponics culture have many advantages such as increased yield, health and uniform product, conservation of water and land , better protect , control of environmental pollution and reduce of workers for cultivation. So in recently years, usage of organic and inorganic substrates obtained more important for greenhouse owners and researchers. The aim of this study was Effects of culture substra...
Date palm, phoenix dactylifera l. (arecales: arecaeae) is the most important crop of the arabian Peninsula. the Kingdom of Saudi arabia is among the top 3 date producing countries of the world estimated to have over 400 date palm cultivars of which 25 are important and yield 1.3 million tons of dates annually. the red palm weevil (RPW) Rhynchophorus ferrugineus (olivier) (Coleoptera: Curculioni...
Local extinctions have cascading effects on ecosystem functions, yet little is known about the potential for the rapid evolutionary change of species in human-modified scenarios. We show that the functional extinction of large-gape seed dispersers in the Brazilian Atlantic forest is associated with the consistent reduction of the seed size of a keystone palm species. Among 22 palm populations, ...
