Crescimento e desenvolvimento do feijoeiro e sua relação com a temperatura a partir dos graus-dias

Summary

Wellington Carvalho, a first-year high school student and scholarship recipient at UFLA, conducted a research project on the phenological development of bean plants (feijoeiro) and their response to temperature variations. His study included comparing plant growth under different temperature conditions, observing how beans grew rapidly during the vegetative phase but stabilized after flowering. He found that beans took longer to complete their lifecycle in colder temperatures. Wellington expressed gratitude to UFLA, CAPES, FAPEMIG, CNPq, and key contributors like Elber and his mentor Paulo for their support in completing the project.

Takeaways

• 😀 Wellington Carvalho is a first-year high school student and a scholarship recipient at UFLA, conducting research on the phenological development of beans.
• 🌱 The project aims to study the growth stages of bean plants, from germination to pod production, and how temperature affects these stages.
• 🌡️ Two trials were conducted: one in warm conditions and one in colder conditions, comparing plant growth and development in different temperatures.
• 📊 The first trial showed that beans grew rapidly during the vegetative phase but slowed down once flowering began, with no significant increase in height or root growth after that.
• 🌾 The second trial, conducted in cooler conditions, also showed rapid growth in the vegetative phase, but the plants took longer to complete their reproductive cycle due to the cold temperature.
• ⚖️ Data collected included dry mass (without water) and fresh mass (with water), measured throughout the plant's life cycle to track growth changes.
• 🌸 In both trials, plant growth stabilized after flowering, with no new leaves or root growth observed after the reproductive phase began.
• ❄️ Temperature had a clear impact on the time taken for the plants to enter the reproductive phase, with cold conditions delaying pod production.
• 🔬 Wellington acknowledges the support of UFLA, CAPES, FAPEMIG, and CNPq for enabling his scientific research and the funding of his project.
• 🙏 Special thanks are given to Elber, who helped with the practical aspects of the project, and to Paulo, the project mentor, for guidance and research support.

Q & A

What was the main focus of Wellington Carvalho's project?

The main focus of Wellington Carvalho's project was the phenological development of the common bean plant (feijoeiro) and its relationship with temperature.

What specific stages of the bean plant's growth were studied in the project?

The project focused on the stages of the bean plant's development, from germination to the production of pods and the plant's death.

What method did Wellington use to track the plant's growth?

Wellington tracked the plant's growth by weighing the mass of the beans with and without water and placing them in an incubator to complete the growth cycle.

What did the first graph show regarding the growth of the bean plant?

The first graph showed that the bean plant grew rapidly during the vegetative phase, with vigorous growth of roots, stems, and leaves, but growth slowed during the flowering phase, with no new roots, leaves, or height increase.

What was the focus of the second experiment Wellington conducted?

The second experiment focused on planting bean seeds in 45 pots during a colder season, to compare the growth patterns with the first experiment.

How did the growth of the bean plants differ in the second experiment?

In the second experiment, the bean plants exhibited similar growth patterns as the first experiment, but the cold weather delayed the plants' transition into the reproductive phase, causing a longer time to complete the cycle.

What did Wellington conclude about the impact of temperature on the bean plant's growth?

Wellington concluded that temperature plays a significant role in the bean plant's growth cycle, with warmer temperatures resulting in faster growth and quicker completion of the cycle, while colder temperatures caused delays in the reproductive phase.

What were the two main variables Wellington measured during his project?

Wellington measured the dry mass of the beans without water and the fresh mass with water to track the plant's growth.

Who assisted Wellington in completing his project?

Wellington received help from Elber, who assisted with the practical aspects of the project, and Paulo, his advisor, who proposed and guided the project.

Which organizations supported Wellington's project?

Wellington's project was supported by UFLA, CAPES, FAPEMIG, and CNPQ, which are research institutions that provided funding and opportunities.
