The objective of these studies was to assess the degree to which bean leaf beetle, Cerotoma trifurcata (Forster), will feed on cucurbits. In 2003, we documented an infestation of C. trifurcata in a commercial pumpkin field near Rosemount, MN, USA. To evaluate C. trifurcata feeding on cucurbits, we conducted laboratory no-choice and choice test feeding studies. In the laboratory, C. trifurcata f...

predicting seed viability would be extremely beneficial to seed producers and the prediction of seed viability depends on understanding the quantitative relationships between seed longevity, seed moisture content and storage temperature. thus, the objective of this investigation was to quantify relationship between temperatures, seed moisture and seed deterioration and determination seed viabil...

The chito-oligosaccharide-specific lectin from pumpkin (Cucurbita maxima) phloem exudate has been purified to homogeneity by affinity chromatography on chitin. After SDS/PAGE in the presence of 2-mercaptoethanol, the pumpkin phloem lectin yielded a single band corresponding to a molecular mass of 23.7 kDa, whereas ESI-MS (electrospray ionization MS) gave the molecular masses of the subunit as 2...

In the Directed Feedback Vertex Set (DFVS) problem, we are given a digraph D on n vertices and a positive integer k and the objective is to check whether there exists a set of vertices S of size at most k such that F = D−S is a directed acyclic digraph. In a recent paper, Mnich and van Leeuwen [STACS 2016 ] considered the kernelization complexity of DFVS with an additional restriction on F , na...

BACKGROUND Plant seeds have gained interest for their health benefits due to their fatty acid content. The objective of this study was to determine the effects of dietary consumption of milled sesame/pumpkin/flax seed mixture on glycemic control, serum lipids, phospholipid fatty acid status, and inflammatory factors in patients on hemodialysis. METHODS Thirty patients with well nutrition stat...

A unique A/T-rich sequence (5'-AAAAAGTAAAAA-GTAAAAAAGTAAAAAG-3), referred to as the AGTA repeat, is found in the silencer region of the pumpkin ascorbate oxidase gene. A cDNA for protein (AOBP) that binds to the AGTA repeat was isolated from pumpkin by the southwestern method. The AOBP protein has a new class of zinc/DNA-binding domain named Dof/MOA domain that is highly conserved in many plant...

Recent declines in managed honey bee, Apis mellifera L., colonies have increased interest in the current and potential contribution of wild bee populations to the pollination of agricultural crops. Because wild bees often live in agricultural fields, their population density and contribution to crop pollination may be influenced by farming practices, especially those used to reduce the populati...

Twelve pumpkin cultivars (Cucurbita maxima D.), cultivated in Iowa, were studied for their seed oil content, fatty acid composition, and tocopherol content. Oil content ranged from 10.9 to 30.9%. Total unsaturated fatty acid content ranged from 73.1 to 80.5%. The predominant fatty acids present were linoleic, oleic, palmitic, and stearic. Significant differences were observed among the cultivar...

in order to investigate the effect of pruning and potassium nutrition on pumpkin grain yield and quality, a factorial experiment based on complete block design with four replications was carried out in nooshar village of ardabil province, ardabil, iran, in 2007. experimental factors include potassium nutrition in three level (0, 75 and 150 kg/ha from potassium sulfate) and stem pruning (without...

Field survey of the cucurbit crops revealed a high incidence of Cucumber green mottle mosaic virus (CGMMV) in Khyber Pakhtunkhwa Province (KPK), Pakistan. Among the seven districts surveyed, average percent incidence of CGMMV was recorded up to 58.1% in district Nowshera, followed by 51.1% in district Charsada, 40.5% in district Swabi and 37.3% in district Mardan. In Swat and Dir districts aver...
