authority(Heywood, 1978; Keil & Walters, 1988). The classification scheme for broccoli and indeed all of the other brassicas is clear and straightforward until one reaches the species level. At that point the addition of numerous subspecies, varieties, and cultivars results in a rather complex and confusing arrangement of-the taxa in question. For example, the scientific name for broccoli, Brassica oleracea (L.), is also shared by cabbage, Chinese cabbage, cauliflower, collards, brussels sprouts, kale, kohlrabi
The Economics of Human Exploration and Migration Somewhere between insatiable curiosity and voracious appetite for the accumulation of wealth lies the motivation for human travel. These two goalposts through which every explorer, merchant and conquistador to roam this planet sailed do not paint the idealized portrait of natural human character, but they nonetheless do accurately depict the aims of those ambitious enough to change the world and therefore merit a place in the halls of history
Evaluation of Fungicide Control of Sclerotinia Stem Rot on Canola (SSR) Yin Chen Description of disease affecting crop Sclerotinia stem rot (SSR) is caused by fungus named sclerotinia sclerotiorum (Lib.) de Bary. It is a common disease in oilseed rape (Brassica napus) field. In Sweden, S. sclerotiorum can cause 60% yield reduction in infected fields (Nordin, 1992). SSR is a major disease of canola in North Dakota. The incidence ranged from 7-19% in North Dakota from 1991 to 1993. ( Lamey, 1995). It occurs
The red cabbage, scientific name: Brassica oleracea var. capitata f. rubra, is also known as purple cabbage. The cabbage is known by this name due to its dark red/purple leaves. It can be found in China, Northern Europe and throughout America. The red cabbage needs sufficient humidity and fertilised soil for it to grow. Red cabbages are planted in spring and harvested in the autumn. This plant changes colour according to the pH level of the soil; the plant contains a pigment flavin (anthocyanins)
At some point in time, human populations decided to settle down and harvest their own food instead of searching for it in the woods. In modern times, people tend to view this as a great advancement or revolution. Why would people want to search for food daily and forage for tubers or berries when they could just head to the supermarket or their own backyard? Scientist have determined, however, that this development brought many negative effects to the human population. The societies who adopted agriculture
