The aim of this work is to chemically characterize olive tree prunings and use the material in hydrothermal and combustion processes. The influence of the hydrothermal treatment conditions, with and without acid catalyst, of the main fraction of olive tree prunings (stems with a diameter > 1 cm) (temperature 150 to 190oC, time 0 to 20 minutes after reaching the operation temperature, liquid/sol...

Almond [Prunus dulcis (Mill.) D.A. Webb] is one of the most important cultivated fruit trees in Iran. Late frost in spring is a key limiting factor for almond productivity given that almond trees flower early in the spring in comparison with other temperate fruit trees. To decrease frost injury in “Mamaei” cultivar, this study was carried out in factorial randomized complete block design (CRBD)...

Crown porosity influences radiation interception, air movement through the fruit orchard, spray penetration, and harvesting operation in fruit crops. The aim of the present study was to develop an accurate and reliable methodology based on transmitted radiation measurements to assess the porosity of traditional olive trees under different pruning treatments. Transmitted radiation was employed a...

A comparison between heavily and lightly browsed Scots pine (Pinus sylvestris) trees revealed that the yield of volatile leaf oil and tree height were highly significantly different. Higher volatile oil yield was positively correlated with lightly browsed trees, and lower oil yield correlated with heavily browsed trees. Tree height was negatively correlated with terpenoid yield, indicating youn...

Allergy is becoming a major disease burden globally. Pollens are considered as the main component of aeroallergens that lead to rhinitis and asthma. Due to the lack of a comprehensive investigation on most allergic pollens of trees in the Middle East, the present study aimed to conduct a comprehensive literature review on this topic. The main goal of the study was to provide a checklist for all...

The application of nutrient solutions to the foliage plants is an alternative means fertilise crops. Foliar fertilisation used overcome disadvantages soil applications. Variable plant responses these foliar spray have often been described in literature. However, knowledge about penetration mechanisms, role a leaf-applied inorganic or organic solution, and results obtained by its still limited. ...

BACKGROUND Grasses and olive trees are the most common sources of allergenic pollen worldwide. Although they share some allergens, there are few studies analyzing the in vitro cross-reactivity between them. The aim was to define the cross-reactivity between Olea europaea and Phleum pratense using well-characterized sera of allergic children from Madrid, Spain. METHODS 66 patients (mean age 10...
