Sapstain fungi on <Emphasis Type="Italic">Pinus radiata</Emphasis> logs – from New Zealand Forest to export in Japan

Supply of clear, unstained logs from an export country is important economically as well as in reducing the biosecurity risk to an importing country such as Japan. Although conditions found within the holds of ships containing logs are thought to be ideal for rapid colonization of sapstain fungi, no research has been conducted. Research-focussed log export trials were designed to determine the extent of sapstain colonisation at specific points in the processing of logs from harvesting to arrival at the export destination. Two trials were established, in the austral summer and winter, in which mature Pinus radiata logs were harvested in New Zealand and shipped to export ports in Japan. Data loggers placed above and below deck of the ships recorded microclimatic conditions. Nine species of sapstain fungi were isolated from logs during the summer trial; the most common species isolated were Ophiostoma floccosum, Ophiostoma querci, and Ophiostoma setosum. In contrast, ten sapstain species were detected during the winter trial, with Sphaeropsis sapinea, O. querci, O. floccosum, and O. setosum most commonly isolated. This research was the first successful attempt at measuring visual sapstain development and isolating sapstain fungi from the time of harvesting to arrival at an export destination.

8个豇豆新品系的比较试验

以之豇28-2为对照,对8个新选豇豆品系的早熟性、农艺性状、抗病性和产量进行了试验比较,试验结果表明,品系2-13-8和5-10-7熟性较早,后期翻花能力强,采收期长,荚长、荚粗和单荚质量有较大优势,田间对枯萎病、疫病、病毒病等表现出较强抗性,前期产量和总产量高,667 m2产量分别达3206.05、3294.98 kg/667 m2,与对照差异分别达显著和极显著水平,因此,2-13-8和5-10-7可作为长沙地区的优良早熟豇豆新品系进行深入研究。
