diverse members of the Cucurbitaceae family come from every corner of the world, but they have been in Southern gardens so long they feel like natives. They have 7 interbreeding and ever-changing species in 3 genera. The genus Cucurbita includes four of them. Cucurbita pepo is the pumpkin, which we know in many variations — the pumpkin, summer squash, cushaws, and gourds. C. maxima, C. mixta, and C. moshuta are true squash, although we know them as winter squash. The genus Cucumis includes cucumbers
the squash family (sometimes referred to as “winter squash”), pumpkins (Cucurbita pepo) are thought to have originated in North America. The oldest evidence of pumpkin seeds, found in Mexico, dated from 7000–5500 BCE. Pumpkins are not actually a vegetable but are more accurately a type of botanical berry or pepo. The word “pumpkin” derives from the Greek pepon, which translates to “large melon”. The giant pumpkins (Cucurbita maxima) grown in South America can exceed one tonne in weight. While mainly
Introduction Pollination and Pollinators Pollination, the transfer of pollen from one flower to another, is a keystone process in both human-managed and natural terrestrial ecosystems. Pollination is one of the most important mechanisms in the maintenance and promotion of biodiversity and, in general, life on Earth. It is an ecosystem process that has evolved over millions of years to benefit both flowering plants and pollinators. Pollination is critical for food production and human livelihood and
catalytic activity of hematin for dye degradation. 92% color removal was noticed for 75 mg l_1 solutions. They presented their results using Doehlert array. They noticed hematin as an effective azo dye removing agent. Boucherit et al. (2013) used Cucurbita pepo (courgette) peroxidase to decolorize Direct Yellow (DY106) and azo dyes. They also noticed the effect of temperature, pH, concentration of H2O2 and enzyme on degradation. The decolourization of DY106 was verified by UV-Vis analysis.
Science that deals with study of materials or any particles that is so small and measured in nanometer scale is called “Nanoscience”. Study about very small particles and its chemical and physical changes at nanoscale is not an easy business. Nanotechnology studies the big picture of those small particles, manipulates them to advance new devices and materials. The name “nanotechnology” was created in year 1974 (Nowack & Bucheli, 2007). But the concept of manipulating Nano particles has been around
