The embryogenic calli induced from the mature embryos of forty - five genotypes of sweet corn varieties were treated as materials to analyze the relationship between plant regeneration and callus induction rate , callus proliferation and bud points 摘要以45种基因型甜玉米的成熟胚为外植体材料，分析出愈率、愈伤组织增殖量、芽点数与植株再生的关系。
Another study on children and adult hypochondria suggests that the melatonin levels of psychiatric patients are lower than those of healthy people . the origin of melatonin melatonin exists in small quantities in many plant species , including oats , sweet corn , rice , ginger , tomatoes , bananas and barley 褪黑激素普遍存于地球上的各种生物体内，食物当中含量较多的有燕麦甜玉米米姜蕃茄香蕉大麦等，但是它们的含量的百分比均不高。
The number of japanese black bears caught feasting in fields of sweet corn , apples and other crops has jumped this year , with the animals increasingly undisturbed by hunters , whose ranks are dwindling as the population ages 日本黑熊在甜玉米地苹果地及种植其它种类农作物的土地中“大吃大喝”的情景如今已经变得越来越频繁，由于该国人口老龄化趋势的进一步加剧，日本猎人的数量也在日渐减少，从而使得黑熊能比以往更少地受到来自猎枪的威胁。

In this paper , the resistance of sweet corn varieties to asian corn borer ( acb ) ( ostrinia nubilalis ) were evaluated by means of host experimental population life table and natural population life table ; the order of their resistibility is as follows : s2 > y3 > h1 > y1 > c20 摘要利用亚洲玉米螟实验种群生命表和自然种群生命表方法评价甜玉米品种对亚洲玉米螟的抗虫性，结果得出亚洲玉米螟对不同甜玉米品种的抗性大小依次为：穗甜2号>奥甜2号>华1 >奥甜1号>超甜20 。
