STUDIES ON THE IMPORTANCE OF WILD BEET AS A SOURCE OF PATHOGENS FOR THE SUGAR‐BEET CROPAnnals of Applied Biology - Tập 48 Số 4 - Trang 771-779 - 1960
Adrian Gibbs
Beet yellows virus, beet mosaic virus, rust (Uromyces betae (Pers) Lév.), and downy mildew (Peronospora schachtii Fuckel.) were found to be common in wild beet (Beta vulgaris s.‐sp. maritima L.) growing on the foreshores of south Wales and southern England. The virus diseases were mo...... hiện toàn bộ
AN AUTOMATIC VOLUMETRIC SPORE TRAPAnnals of Applied Biology - Tập 39 Số 2 - Trang 257-265 - 1952
J. M. Hirst
A suction trap has been made in which the spores entering a narrow orifice, directed into the wind, are impacted on a Vaseline‐coated microscope slide moved across the orifice at 2 mm./hr. Estimates of spore content of the air can be made, with higher efficiency than by previous traps, at different times of day and thus be more closely correlated with variations in weather.... hiện toàn bộ
Genotype to phenotype: a technological challengeAnnals of Applied Biology - Tập 142 Số 1 - Trang 33-39 - 2003
Ian Wilson, Gary Barker, Keith J. Edwards
SummaryOur ability to ascribe protein function from primary DNA sequence or to predict the wide‐ranging effects of up or down regulating a single gene is still almost non‐existent. While the acquisition of raw genomic data proceeds apace, our capacity for converting this information into useful knowledge is limited. Within the next few years this “gap” will no doub...... hiện toàn bộ
Genetic basis of yield as viewed from a crop physiologist's perspectiveAnnals of Applied Biology - Tập 142 Số 2 - Trang 117-128 - 2003
Gustavo A. Slafer
SummaryThe final yield of a crop is the product of growth during the growing season and a number of developmental processes occurring throughout the life cycle of a crop, with most genes influencing the final outcome to a degree. However, recent advances in molecular biology have developed the potential to identify and map many genes or QTLs related to various impo...... hiện toàn bộ
Isolation, characterisation and identification of a potyvirus from Dioscorea alata L. (water yam) in NigeriaAnnals of Applied Biology - Tập 134 Số 1 - Trang 65-71 - 1999
B. O. Odu, J. Hughes, S. A. Shoyinka, L. N. Dongo
SummaryA yam potyvirus was isolated from Dioscorea alata samples collected in Nigeria. The virus was not transmissible mechanically but was transmitted by Aphis craccivora to four cowpea cultivars (Ife Brown, IT84S‐2114, IT82E‐10 and TVu2657), and from which it could be mechanically transmitted between the cowpe...... hiện toàn bộ
Resource distribution and the trade‐off between seed number and seed weight: a comparison across crop speciesAnnals of Applied Biology - Tập 156 Số 1 - Trang 91-102 - 2010
Brenda L. Gambín, Lucas Borrás
In grain crops, total sink capacity is usually analysed in terms of two components, seed number and individual seed weight. Seed number and potential individual seed weight are established at a similar timing, around the flowering period, and seed weight at maturity is highly correlated with the potential established earlier. It is known that, within a species, available resources during t...... hiện toàn bộ
Phenolic compounds in peach (Prunus persica) cultivars at harvest and during fruit maturationAnnals of Applied Biology - Tập 153 Số 1 - Trang 11-23 - 2008
Carlo Andreotti, Daniela Ravaglia, Alessandro Ragaini, G. Costa
AbstractSix peach and six nectarine cultivars were evaluated for the phenolic content in their pulp and peel tissues. Chlorogenic acid, catechin, epicatechin, rutin and cyanidin‐3‐glucoside were detected as the main phenolic compounds of ripened fruits. The concentration was always higher in peel tissue, with average values ranging from 1 to 8 mg g−1... hiện toàn bộ
Food security: the challenge of increasing wheat yield and the importance of not compromising food safetyAnnals of Applied Biology - Tập 164 Số 3 - Trang 354-372 - 2014
Tanya Y. Curtis, Nigel G. Halford
AbstractCurrent wheat yield and consumption is considered in the context of the historical development of wheat, from early domestication through to modern plant breeding, the Green Revolution and wheat's place as one of the world's most productive and important crops in the 21st Century. The need for further improvement in the yield potential of wheat in order to ...... hiện toàn bộ
Deficit irrigation in grapevine improves water‐use efficiency while controlling vigour and production qualityAnnals of Applied Biology - Tập 150 Số 2 - Trang 237-252 - 2007
M. M. Chaves, T. P. dos Santos, C. R. de Souza, M.F. Ortuño, M. L. Rodrigues, Carlos M. Lopes, João Marôco, J. S. Pereira
AbstractGrapevine irrigation is becoming an important practice to guarantee wine quality or even plant survival in regions affected by seasonal drought. Nevertheless, irrigation has to be controlled to optimise source to sink balance and avoid excessive vigour. The results we present here in two grapevine varieties (Moscatel and Castelão) during 3 years, indicate t...... hiện toàn bộ
