Document Summary
Most plants: c3 (3-carbon) plants c3: rice, wheat, etc. Very wet and hot: rice; root crops (cassava, yam, sweet potato) and bananas/plantains. Lesson 10: asian rice is genetically divided into two subspecies: Japonica: short grain sticky rice, today in china, east asia with chopsticks sticky rice from teriyaki experience. Indica: long grain, non-sticky, today in south asia, eaten by hand (uncle ben"s rice - we eat this one) Lesson 11: in terms of cultivation, there are two major types of rice: upland rice (seeds planted in soil) and paddy rice (seedlings transplanted into water) Paddy rice has aerenchyma (holes in stems and roots which allow oxygen to travel to roots so they don"t drown) Advantages of paddy rice: water suppresses weeds, early start in nursery so shorter season, also associated with a water fern/bacteria that makes nitrogen fertilizer, supports fish communities (as a protein source)
