摘要
本文对1985年12月至1986年3月期间7次在四川省西昌地区所采云南松种子的品质和活力进行了研究。结果表明:2月上旬以后采集的种子比较成熟,出种率和发芽率高,抗逆性强,耐贮性好,活力高;2月上旬至3月上旬为西昌地区云南松种子最适宜的采种期;球果含水量可作为确定采种期的指标之一。在本研究的采种期内,种子中脂肪和可溶性糖含量变化不明显。
The quality of Yunnan pine seeds from cones harvested at seven dates from December, 1985 to March, 1936 in Xichang region, Sichuan Province has been studied. It was found that seeds from cones harvested before early February not only were lower in germination percent, germination energy and seed vigour expressed as emergence percent, simplified vigour index and seedling vigour classes, but also deteriorated more rapidly during storage, compared with seeds from cones harvested after that time. It was confirmed that harvesting period for Yunnan pine seed in the region is from early February to early March. 18%?3%, moisture content of cones could be used as an index of their collection season. Contents of lipids and soluble sugars of seed harvested freom December to March were not changed apparently.
