| damage by tibraca limbativentris stål (pentatomidae) to upland rice cultivated in amazon rainforest region (brazil) at different growth stages. | in this study, we evaluated the damage caused in the field by tibraca limbativentris stål adults at different levels of infestation (0, 1, 2, and 4 stink bugs) per three rice plants during three growth stages (v8, v13, and r4 stages) of upland rice cultivated in southwestern of pará state, amazon rainforest region, brazil. heading time (panicle exertion) was affected by t. limbativentris infestations mainly in the vegetative stage and the whiteheads percentage in treatments ranged from 18.2 to 3 ... | 2017 | 27558273 |
| dark septate endophyte decreases stress on rice plants. | abiotic stress is one of the major limiting factors for plant development and productivity, which makes it important to identify microorganisms capable of increasing plant tolerance to stress. dark septate endophytes can be symbionts of plants. in the present study, we evaluated the ability of dark septate endophytes isolates to reduce the effects of water stress in the rice varieties nipponbare and piauí. the experiments were performed under gnotobiotic conditions, and the water stress was indu ... | 2017 | 28089614 |
| evidence for mid-holocene rice domestication in the americas. | the development of agriculture is one of humankind's most pivotal achievements. questions about plant domestication and the origins of agriculture have engaged scholars for well over a century, with implications for understanding its legacy on global subsistence strategies, plant distribution, population health and the global methane budget. rice is one of the most important crops to be domesticated globally, with both asia (oryza sativa l.) and africa (oryza glaberrima steud.) discussed as prim ... | 2017 | 28993622 |
