辣椒常见异常种子发芽率试验研究

Study on Germination Rate of Common Unusual Seeds of Hot Pepper

进行辣椒常见异常种子发芽试验研究,结果表明:常见异常辣椒种子的发芽率、始发芽时间、发芽集中整齐度和幼苗生长量均低于正常种子。在24℃的恒温催芽条件下,发芽率依次为正常种子(98.00%)、种皮霉变种子(91.00%)、黑斑种子(5.67%)、不饱满种子(0.33%);正常种子和种皮霉变种子在催芽后第3天开始发芽,第4天处于发芽高峰,高峰日发芽率分别为66.67%和61.00%。黑斑种子和不饱满种子在催芽后第6～8天开始发芽,第7～8天为发芽高峰期,高锋日发芽率分别为3.67%和0.33%;发芽第10天芽长依次为正常种子(35.00 cm)、种皮霉变种子(28.00 cm)、黑斑种子(11.33 cm)、不饱满种子(3.67 cm)。根长依次为种皮霉变种子(66.00 cm)、正常种子(59.33cm)、黑斑种子(10.00 cm)、不饱满种子(6.33 cm)。

The germination rate of common Unusual seeds of hot pepper was studied.The results showed that the germination rate, the beginning germinating time ,the tidy degree of germination and the seedling growth quantity of common unusual hot pepper seeds were lower than those of the normal seeds by the experiment.Under 24 ℃,the germination rates of the normal seeds ,the moldy seeds ,black spot seeds and unsaturated seeds were 98.00% ,91.00% ,5.67% and 0.33% ,respectively ;The normal seeds and the moldy seeds began germinate in the third day after sprouting.The germination rates were 66.67% and 61.00% during the peak.The black spot seeds and unsaturated seeds began to germinate in the 6-8 d after sprouting. The germination rates were respectively 3.67% and 0.33% during the peak, the bud length of the normal seeds, the moldy seeds, black spot seeds and unsaturated seeds were respectively 35.00 cm,28.00 cm, 11.33 cm and 3.67 cm.The root lengths were respectively 59.33 cm, 66.00 cm, 10.00 cm and 6.33 cm in the tenth day.
