小麦种子贮藏特性及技术要点 总被引:2,自引:0,他引:2
种子是有生命的有机体,贮藏条件的优劣和贮藏期间管理的好坏,直接影响着种子质量。所以,种子贮藏是搞好种子生产和营销的关键,是实现种子产业化的重要环节。小麦种子收获时正逢高温、多湿气候,即使经过充分干燥,人库后如管理不当,仍易吸湿回潮、生虫、发热、霉变,贮藏较为困难,因此,必须引起高度重视。 相似文献

不同贮藏年限和贮藏方法对党参种子发芽的影响 总被引:1,自引:0,他引:1
通过对不同贮藏年限、贮藏方法党参种子发芽率、发芽势进行测定与分析,结果表明,贮藏1年的党参种子与新采收的种子相比,发芽率降低50.85%,发芽势降低40.21%,贮藏3年以上的种子发芽率不足10%,发芽势不足5%,在生产上基本无种用价值。在常温条件下用布袋或麻袋贮藏党参种子可减缓生活力的降低,适用于生产中的种子贮藏。 相似文献

Strong seedlings are essential for high yield. To explore the foundation of strong seedlings, we investigated various factors influencing the conversion and distribution of seed storage reserves during seedling establishment in maize inbred lines. Three maize inbred lines were used to explore the effects of seed size, seed vigor, illumination duration, temperature, water content, and salt concentration of the seedling medium on the utilization of seed storage reserves during seedling establishment. The results showed that the conversion rate of small seeds was 3.69 to 17.71% higher than that of large seeds. Moreover, prolonged illumination time was conducive to the formation of strong seedlings. However, low temperature, drought stress and salt stress reduced the conversion rate of seed storage reserves and increased the root/shoot ratio. These results could be used to guide field management during seedling emergence and develop improved germplasm with a high conversion rate of seed storage reserves. 相似文献

A major challenge for the management of gene banks is the maintenance of good seed health in the collections. Large germplasm collections 10 000 accessions often have been acquired from different sources over a range of dates, may differ in germination at time of deposition in the gene bank, and may have genetic differences in seed longevity. The major storage variables affecting seed longevity are temperature and seed moisture content. Two varieties of each pea(Pisum sativus L.), lentil(Lens culinaris Medikus subsp. culinaris), and chickpea(Cicer arietinum L.), were stored at three temperatures; 40, 20, and 2°C, each with three seed moisture levels of 10.9–13.8%(high), 7.9–10.3%(medium), and 7–7.8%(low), in the Australian Temperate Field Crops Collection gene bank. Seed longevity at a given storage period was estimated by the corresponding germination percentage for each treatment. This paper is an interim report on seed viability decline in the first seven years of this seed longevity study, in which viability decline towards zero was almost completed in the three seed moisture treatments at 40°C and the 20°C high seed moisture treatment, but had not declined in the other treatments. Seed longevity positively responded to a reduction in temperature and then to a reduction in seed moisture. The number of days in storage for seed germination decline to 85%(p85), and to 50%(p50) for mean seed viability, are reported by storage/varietal treatment. Both p85 and p50 showed significant inverse linear responses with seed moisture at 40°C for pea and lentil varieties, with intra-specific variation for pea. This long term trial aims to provide informed timing of seed regeneration for accessions in a gene bank. 相似文献
