菠芽种子皮厚壳硬,发芽时间较长,恒温测定发芽率需10天左右,影响正常托收和供种我们进行了变温催芽试验,结果6天左右就完成了。具体做法是: 取大叶菠芽籽490粒,分4次重复,每次处理100粒。将种子在15-20℃(室温)条件下浸种8-24小时,尔后用清水洗干净,稍晾干表面水分,再用消过毒的湿毛巾包好,放在瓷盘里催芽,盖要留出缝隙,以利通气,每天翻动一次,每隔两天用清水冲洗一次。催芽变温的范围是,晚上13-15℃16小时,白天20℃8小时,交替处理。这样24小时后就有少量种子出芽,6昼夜后能发芽的种子基本发芽,即
Sprout seed shell thick hard shell, sprouting time longer, the temperature measured germination rate of about 10 days, affecting the normal collection and supply we conducted a temperature sprout test, the results of about 6 days to complete. Specific approach is: Take big leaf spinach seeds 490, divided into 4 replicates, each processing 100. Soak the seeds at 15-20 ℃ (room temperature) for 8-24 hours, then wash with water, slightly dry the surface moisture, wrapped with sterile wet towel, germination on the porcelain plate, covered Leave a gap to facilitate ventilation, flip once a day, rinse once every two days with water. Germination temperature range is 13-15 ℃ 16 hours at night, 20 ℃ 8 hours during the day, alternating treatment. After 24 hours there is a small amount of seed germination, seed germination can be basically germinated after 6 days and nights, that is
