This list of the North American vegetable cultivars was developed using the database of cultivars registered with the American Seed Trade Association, as well as published descriptions from scientific journals and seed catalogs. Assistant editors responsible for each crop were instructed to obtain as much information as possible about the cultivars available to North American growers. The crop ...

Triacylglycerols from plants, familiar to most people as vegetable oils, supply 25% of dietary calories to the developed world and are increasingly a source for renewable biomaterials and fuels. Demand for vegetable oils will double by 2030, which can be met only by increased oil production. Triacylglycerol synthesis is accomplished through the coordinate action of multiple pathways in multiple...

Recently published research has identified that the use of a ‘wine-like’ 15% ethanol extraction method when analysing grape tannins provides a strong indication of tannin concentration that is likely to result when those grapes are made into wine. The AWRI has developed a rapid and practical method for determining extractable tannins in red grapes, which involves gentle crushing of grapes by ha...

The MW profiles of proanthocyanidin polymers (condensed tannins) from 32 samples representing a wide range of plant tissues of many different species have been obtained by gel permeation chromatography of the peracetate derivatives. The tannins vary widely in MW, with Al. values for the peracetates in the range 1600-5500. The MW profiles vary greatly from those with narrow, rather smooth distri...

Shallots (Allium cepa) and garlic sativum) are kind of the plants that widely planted distributed in Indonesia. The tropical climate fertile soil Indonesia make shallots easy to grow only by cultivating seeds or bulbs. type vegetable forming a small bulb-like shape which can be used flavor food (spices seasoning); lower cholesterol; overcome acnes, inflammation; acting as antioxidants, antimicr...

Ziziphus mauritiana Lam. is an important medicinal plant belonging to the family Rhamnaceae. Preliminary phytochemical screening of the leaf extract of Ziziphus mauritiana revealed presence of different types of secondary metabolites such as glycosides, tannins, phenols and saponins. The methanol leaf extracts of Ziziphus mauritiana showed significant activity against Staphylococcus aureusand E...

To date, it remains unclear how herbivore-induced changes in plant primary and secondary metabolites impact above-ground and below-ground herbivore interactions. Here, we report effects of above-ground (adult) and below-ground (larval) feeding by Bikasha collaris on nitrogen and secondary chemicals in shoots and roots of Triadica sebifera to explain reciprocal above-ground and below-ground inse...
