1.文冠果国家标准中文冠果种子生活力测定方法规定“用浓硫酸浸泡3小时,洗净,再用40℃温水浸种2日”即可剥开种皮取胚。但多次试验结果证明:文冠果用试剂门市部出售的浓硫酸浸泡(浓度95～98％),最多浸泡2小时,外壳即变红、蚀烂、胚萎缩而死亡。如果浸泡时间过短,则种壳依旧很坚硬,适宜的浸泡时间不好掌握。通过多次反复试验,摸索出一种简便易行、花钱少,而又能保证生活力及测定结果准确性的方法。具体做法是;用45～60℃温水浸泡3～4天,每天换水两次,待种粒泡胀后,用牙轻轻咬破一点种皮,或用小刀挑破一个小口,
1. The Chinese crown of the national standard Chinese crown fruit seed vitality determination of the provisions of “soaked with concentrated sulfuric acid for 3 hours, washed, and then 40 ℃ warm water soaked 2 days” can be stripped seed coat embryo. But many times the test results show that: the text of the fruit of the store sales of concentrated sulfuric acid reagent soaked (concentration 95-98%), up to 2 hours soaking, the shell becomes red, corroded, embryo atrophy and death. If the soaking time is too short, the shell is still very hard, suitable for soaking time is not good grasp. Through repeated trial and error, we have explored a simple and easy way to spend less money while ensuring vitality and measuring the accuracy of results. The specific approach is: soak 45 ~ 60 ℃ warm water for 3 to 4 days, changing the water twice a day until the seeds swollen, the teeth gently bite a little skin, or use a knife to pick up a small mouth,
