概括
由非洲奴隶后裔种植的马龙大米的土地种类,在传统农业系统中种植时,可以产生远高于以前假定的产量. 这项研究强调了在本土农业环境中评估陆地品种对于准确的绩效评估的重要性.
科学领域:
- 农业科学 农业科学
- 民族植物学 民族植物学
- 农作物科学 农作物科学
背景情况:
- 传统的大米土地品种往往是选择超出高产量的特征,如抗压力和成熟时间.
- 苏里南和法属圭亚那的Maroon社区保留了独特的非洲大米土地种的多样性,历史上与他们的逃亡和定居联系在一起.
- 之前对马龙大米的低产量 (700-1000公斤/公) 的假设在传统农业系统中缺乏经验验验证.
研究的目的:
- 在传统的农业条件下,研究马龙的实际产量表现.
- 在相同的传统农业环境下,将Maroon陆地品种的产量与商业品种进行比较.
- 评估马大米在陆地品种类别中的成熟时间和变异性.
主要方法:
- 实地研究涉及28种Maroon大米和两个商业品种的生长和收获.
- 试验在三个不同的地点在传统的Maroon农民田里进行.
- 采用传统的农业方法,不使用农业化学品或机械.
主要成果:
- 在农民管理的田地里,米的土地种类的产量高达2600公斤/公 (平均1665公斤/公).
- 商业品种在同一个领域的产量明显较低 (625-1205公斤/公),部分原因是鸟类的掠食.
- 成熟时间从110天到183天不等,短期,中期和长期成熟类别之间有相当大的重叠.
结论:
- 棕大米的土地种类在传统农业系统中表现出相当大的产量潜力.
- 这些陆地品种的表现与传统的养殖方法和环境密切相关,这些传统的养殖方法和环境是它们的发展和选择.
- 准确评估Maroon大米需要在传统的Maroon农业系统中进行评估,挑战关于其生产力的先前假设.

Trihybrid Crosses
Some of Mendel’s crosses examined three pairs of contrasting characteristics. Such a cross is called a trihybrid cross. A trihybrid cross is a combination of three individual monohybrid crosses. For example, plant height (tall vs. short), seed shape (round vs. wrinkled), and seed color (yellow vs. green).
The F1 generation plants of a trihybrid cross are heterozygous for all three traits and produce eight gametes. Upon self-fertilization, these gametes have an equal...
