Abstract:
... A pectic polysaccharide (WAP) was isolated from squash and identified as a homogalacturonan with a molecular mass of 83.2 kDa by GPC, monosaccharide composition analysis, FT-IR and NMR spectra. Sulfation modification of WAP was carried out and a sulfated derivative (SWAP) was obtained with a substitution degree of 1.81. The NMR spectrum indicated that the sulfation modification mainly occurred at ...

Abstract:
... In common narratives of emergency food assistance, donors likely believe their efforts directly manifest as people consuming their donated food. For example, a person donating canned lima beans during a canned food drive may visualise someone eventually eating those lima beans. However, cultural and socio-economic barriers often exist that prevent people from accessing and consuming the donated fo ...

Hybrid incompatibility and F₁ hybrid dysgenesis in the interspecific hybridization between pumpkin (Cucurbita moschata Duch.) and winter squash (Cucurbita maxima Duch.) have been previously noted. For this reason, it is difficult to obtain F₂ generations due to F₁ sterility. However, back-crossing and add-crossing can be utilized to overcome these incompatibility barriers in interspecific hybridiz ...

The yield of many agricultural crops depends on pollination services provided by wild and managed bees, many of which are experiencing declines due to factors such as reductions in floral resources. Thus, improving pollinator habitat on farmlands using management strategies like planting wildflower strips is vital for wild bee conservation and sustainable crop pollination. Yet, few studies have ex ...
