Twenty-one open pollinated populations of peach rootstock seedlings were evaluated for their response to infection by the root lesion nematode, Pratylenchus penetrans, over a period of 98 days. Nematode-infected peach seedling populations were shorter in plant height and had less shoot weight but more dry root weight than nematode-free controls. Rootstock differences were demonstrated for nemat...

Sixty rhizosphere soil samples of apple seedlings and rootstock were collected from six nurseries of Khuzdar and Kalat districts of Balochistan. Six different plant nematodes were found associated with the seedlings and rootstock. The most predominant nematode was Xiphinema americanum, whereas the nematode found from a single locality was Tylenchus butteus. A matrix of similarities with respect...

BACKGROUND Olfactory stimulation is an often overlooked method of environmental enrichment for cats in captivity. The best known example of olfactory enrichment is the use of catnip, a plant that can cause an apparently euphoric reaction in domestic cats and most of the Pantherinae. It has long been known that some domestic cats and most tigers do not respond to catnip. Although many anecdotes ...

Differencing between green cover and grape canopy is a challenge for vigour status evaluation in viticulture. This paper presents the acquisition methodology of very high-resolution images (4 cm), using a Sensefly Swinglet CAM unmanned aerial vehicle (UAV) and their processing to construct a 3D digital surface model (DSM) for the creation of precise digital terrain models (DTM). The DTM was obt...

Systemic activity of the neonicotinoids clothianidin, dinotefuran, and thiamethoxam and the anthranilic diamide chlorantraniliprole was tested against adult black vine weevils, Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae), on Astilbe, Euonymus, Heuchera, Rhododendron, Sedum, and Taxus. Insecticide treatments were applied to the soilless substrate of containerized plants. Bioassays wer...

The reproducible quality of phytopharmaceuticals--herbal medicines--is an essential prerequisite for good efficacy and tolerability in the treatment of functional disorders. In clinical trials and scientific investigations, standardized assessments (i.e., validated, internationally recognized and accepted scales) provide the basis for establishing clinical efficacy and tolerability. Extracts (e...

The objective of this study was to compare the growth of three Leucadendrons (Proteaceae) cultivars (`Safari Sunset', `Orot' and `Meir') fertigated with three levels of P. The plants were grown in tuff (pyroclastic material, characterized by high porosity) in 10 l pots and fertigated daily. The experiment included control treatment (plants irrigated with tap water) and three levels of P (0, 10 ...

Introduction: Squirting cucumber, Ecballium elaterium (L.) A. Rich. (Cucurbitaceae), is a wild medicinal plant found abundantly in the Mediterranean region. It has been utilized as a rootstock for many cucurbitaceous crops, mainly attributed to its resistance to abiotic as well as biotic stress (2). Important pharmacological uses (1, 9) are attributed to the bitter principles, cucurbitacins (5)...
