Potential for Ribes Cultivation in North America
Fruit from black, red and white currants, and gooseberries (Ribes L.) were grown commercially in North America at the beginning of the 20th Century. However, when white pine blister rust (WPBR) (Cronartium ribicola J. C. Fisch.) was introduced into the new world, their cultivation was discontinued. About 825,000 t (908,000 tons) of Ribes fruit are produced worldwide, almost entirely in Europe. ...

متن کامل/?-Carboline Alkaloids from Ribes nigrum L
From Ribes nigrum L. two ß-carboline alkaloids (deshydroxymethyl flazin (1) and flazin methyl ether (2)) could be isolated in minute amounts. The structure elucidation is described. The two compounds are present in the freshly pressed juice, but they are also formed during storage of the juice by condensation of tryptophane with ascorbic acid or its degradation products. This could be shown by ...
متن کاملAntiproliferative Properties of Embelia Ribes
Embelia ribes is a threatened woody shrub belonging to the family Myrsinaceae, which is sparsely distributed in the moist deciduous forests of the Western Ghats in India. The previous reports showed the effect of Embelin in methylcholanthrene induced fibrosarcoma in albino rats besides enhancing their survival time. Embelin provided a good support for the chemopreventive effect against Nnitroso...
متن کاملChilling requirement of Ribes cultivars
It is usually thought that adequate winter chill is required for the full flowering of many temperate woody species. This paper investigates the sensitivity of blackcurrant bud burst and flowering to natural weather fluctuations in a temperate maritime climate, and compares a range of chill models that have been proposed for assessing the accumulation of winter chill. Bud break for four contras...
