６５个菠菜品种的性型表现：植株群体雌雄比约为１∶１。就单个品种而言，有１／３的品种雌雄之比不符合１∶１。对４个品种进行了不同播期、氮肥条件下雌雄比观察，发现潍坊尖叶的性型表现仅受遗传因子控制，而其他３个品种的性型既受遗传因子控制，也受环境因子影响。短日照、低温、氮肥多的情况下，雌株率高；长日照、高温、氮肥少的情况下，雄株率高
The performance of 65 varieties of spinach: plant population male to female ratio of about 1: 1. For a single breed, one third of the breeds do not fit the ratio of 1: 1. Four sows were sowed at different sowing dates, and the ratio of male and female under nitrogen fertilizer was observed. The results showed that the sexual performance of the tip leaves of Weifang was controlled only by genetic factors, while the other three varieties were controlled by both genetic factors and environmental factors . Under the conditions of short sunshine, low temperature and large amount of nitrogen fertilizer, the female plant rate is high. In the case of long sunshine, high temperature and low nitrogen fertilizer, the male plant rate is high
