The use of engineered nanomaterials has increased as a result of their positive impact on many sectors of the economy, including agriculture. Silver nanoparticles (AgNPs) are now used to enhance seed germination, plant growth, and photosynthetic quantum efficiency and as antimicrobial agents to control plant diseases. In this study, we examined the effect of AgNP dosage on the seed germination ...

Previous research indicates that the Nanchoc Valley in northern Peru was an important locus of early and middle Holocene human settlement, and that between 9200 and 5500 (14)C yr B.P. the valley inhabitants adopted major crop plants such as squash (Cucurbita moschata), peanuts (Arachis sp.), and cotton (Gossypium barbadense). We report here an examination of starch grains preserved in the calcu...

Pumpkin (Cucurbita spp.) has received considerable attention in recent years because of the nutritional and health-protective value of seed oil. The nutritional composition of pumpkin native to central Italy, locally known as "Berrettina" (Cucurbita maxima L.), was evaluated. In particular, the lipid fraction of seed oil was characterized, and the triacylglycerol (TAG) was thoroughly studied by...

Cucurbitaceae, Cucurbita maxima, Tracer Experiments, Potash Fusion, Sporopollenin The results of tracer experiments performed with anthers of Tulipa cv. Apeldoorn have already shown that a high level of incorporation into the sporopollenin fraction was achieved, when [14C]phenylalanine was applicated as a precursor. In order to investigate whether the substantial incorporation of [14C]phenylala...

The objective of this study was to develop a cereal-pulse complementary food fortified with different concentrations of pumpkin powder (Cucurbita moschata), and to analyse its sensory and physic-chemical parameters. Fresh pumpkins(Cucurbita moschata) were procured from the market and dehydrated and powdered in the laboratory. Sorghum (Sorghum vulgare) and whole green gram (Vigna radiate) were g...

In the study, two commercial Cucurbita maxima×Cucurbita moschata hybrid (Nun9075 and TZ148), Lagenaria spp. (Argentario) one local genotype (3335) Citrullus amarus (PI 296341) were used as rootstocks. The male female parents of watermelon hybrids (187×125 11×162) scions. Ungrafted plants formed control group also each parent was grafted on itself. Male for pollen measurements. Fruit weight, fru...

La polinización es de suma importancia para la agricultura, y son los insectos unos más importantes polinizadores. Las plantas atraen aseguran visita polinizadores a través sus flores. Sin embargo éstas también pueden atraer otro tipo visitantes, por tanto, el conocer rasgos florales que influyen en las visitas clave cultivos, podría conducir mejoras rendimiento. Se compararon atributos flores ...

cercosporoid fungi including the genus cercospora and other morphologically similar genera are associated with leaf spot symptoms on various host plants. in this research three taxa including passalora cucurbiticola (on cucurbita sp.), p. bolleana (on ficus carica), and pseudocercosporella capsellae (on capsella bursa-pastoris, sinapis arvensis) were identified. among these, p. cucurbiticola an...
