African oil palm (Elaeis guineensis) is an important oil crop grown in tropical region and sensitive to low temperature along with high tolerance to salt and drought stresses. Since the WRKY transcription factor family plays central roles in the regulation of plant stress tolerance, 95 genes belonging to the WRKY family were identified and characterized in oil palm genome. Gene structure analys...
In this paper, we propose a vision based palm tracking method with three inherently connected components: i) an offline palm detector that locates all possible palm-like objects; ii) a SURF-based tracking module that identifies the tracked palm’s location using historical information; iii) an adaptive skin color model and a patch similarity calculation module. The outputs from the last componen...
The product ion of crude palm oil and palm kernel is a complex problem due to the inf luence of processing variables and environmental factors. These processing variables inf luence the amount of crude palm oil and palm kernel losses during processing. Instead of mathematical model, fuzzy logic approach provides a simpler and easier mechanism to describe the relat ionships between the processin...
ZTsing 325-mesh tantalum powder as a contrast medium, it is possible to take high-resolution “radiodermatographs” of man and infra-human primates that combine the advantages of postero-anterior hand radiographs and conventional paper palm-and-finger prints. The radiodermatographs are particularly useful in relating creases, triradii and fingertip ridge patterns to differences in the proportions...
We quantitatively studied the excitatory receptive fields of 297 neurons recorded from the forelimb infragranular somatosensory cortex of the rat while touch stimuli were applied to discrete locations on the forelimbs. Receptive fields were highly heterogeneous, but they were regulated, on average, by an underlying spatio-temporal structure. We found the following. (i) Neurons responded with de...
Peach palm (Bactris gasipaes Kunth) was commercially introduced in São Paulo the 1980s, as an alternative for heart-of-palm production, being currently main species cultivated this purpose. Phenological studies on fowering/fruiting, addition to contributing breeding program, can provide subsidies seed production technology. The objective of research evaluate reproductive phenology peach palm, r...
Rhynchophorus ferrugineus (Olivier) (Coleoptera: Dryophthoridae) larvae are cryptic, internal tissue-feeding pests of palm trees that are difficult to detect; consequently, infestations may remain hidden until they are widespread in an orchard. Infested trees and propagable offshoots that develop from axillary buds on the trunk frequently are transported inadvertently to previously uninfested a...
Oil palm supplies >30% of world vegetable oil production1. Plantation expansion is occurring throughout the tropics, predominantly in Indonesia, where forests with heterogeneous carbon stocks undergo high conversion rates2–4. Quantifying oil palm’s contribution to global carbon budgets therefore requires refined spatio-temporal assessments of land cover converted to plantations5,6. Here, we rep...
date palm spider mite is one of the major pests of date palm in khuzestan.this pest damages fruits in orchards. in the present study responses of 30 native date palm cultivars of khuzestan were evaluated by assessment of pest infestation severity and fruit damage characteristics. based on the responses, cultivars were clustered into four groups as very highly infested cultivars including liloei...
BACKGROUND A green approach to synthesize nanomaterials using biotemplates has been subjected to intense research due to several advantages. Palm olein as a biotemplate offers the benefits of eco-friendliness, low-cost and scale-up for large scale production. Therefore, the effect of palm olein on morphology and surface properties of ZnO nanostructures were investigated. RESULTS The results i...
