Some components of the air‐spora in Jamaican banana plantationsSUMMARY The air in several Jamaican banana plantations was sampled from July 1960 to September 1961 with an automatic volumetric spore trap. In dry weather, many fungi showed typical diurnal periodicity. Group I fungi (Deightoniella, Nigrospora, Cordana, Corynespora, Zygosporium and Zygophiala ) first appeared sho... ... hiện toàn bộ

Maternal effects in progeny of field pansy (Viola arvensis) subjected to different herbicide and nitrogen ratesSummary Observations were made on the effects of reduced rates of herbicide and nitrogen on naturally occurring populations of Viola aruensis. Progeny arising from these plants were grown in a uniform environment and monitored through to maturity. The size and number of reproductive structures produced by the maternal plants were positively correlated with the mater... ... hiện toàn bộ

Genetic basis of yield as viewed from a crop physiologist's perspectiveSummary The 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 NigeriaSummary A 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

THE INFLUENCE OF NOSEMA APIS ON THE LARVAL HONEYBEEIn experiments on the infection of bee larvae with Nosema apis , the parasitic spores did not germinate and infected adults did not result. In hives of bees infected with N. apis about 10–20% of the eggs laid did not complete their development probably because of inadequate care and feeding.

STUDIES ON THE PROPERTIES OF SOIL‐BORNE VIRUSES OF THE TOBACCO‐RATTLE TYPE OCCURRING IN SCOTLANDSoil‐borne viruses of the tobacco‐rattle type occur in sandy and peaty soils in many parts of Scotland, and infect many species of crop and weed plants, often only in the roots. They also occur in potato plants that have diseases of the stem‐mottle type. The viruses can be distinguished from other soil‐borne viruses occurring in Britain by the symptoms they cause in tobacco, C... ... hiện toàn bộ

A rapid technique for analysing diets of invertebrate predators by electrophoresisSUMMARY A technique has been developed for the rapid determination of some species of prey consumed by mites and insects. The method detects prey enzymes within the gut of a predator by polyacrylamide gradient gel electrophoresis and subsequent staining for esterase activity. It is sufficiently sensitive to detect fruit tree red spider mite (Panonychus ulmi) esteras... ... hiện toàn bộ

An analysis of leaf growth in sugar beet.SUMMARY The expansion and persistence of leaves of sugar beet (Beta vulgaris ) were measured in a series of crops grown in five seasons between 1978‐82 to establish how their growth varied between seasons, was affected by certain agronomic treatments and contributed to changes in leaf area index. Thermal time (accumulated temperature above ... ... hiện toàn bộ

Methods for inoculating field crops with mycorrhizal fungiSUMMARY Four methods were compared for inoculating red clover with selected mycorrhizal fungi when sown in a field containing an indigenous mycorrhizal population. The largest amount of mycorrhizal infection (around 65% of root length infected) was obtained by placing inoculum with the seeds in furrows. The inoculum used was standard soil inoculum from stock plant c... ... hiện toàn bộ

Abundant genetic diversity of the wild rice Zizania latifolia in central China revealed by microsatellitesAbstract Wild rice Zizania latifolia is a perennial emergent aquatic plant widely distributed across China. Wild populations of Z. latifolia are important to aquatic ecosystems and are valuable genetic resources for breeding. However, they have been faced with significant habitat losses in recent decades. For 10 ... ... hiện toàn bộ
