Venus is the second planet from the sun and is the brightest object in the night sky after the Moon. It is often referred to as the Earth's sister planet due to its similar size, mass, and composition. The name Venus is derived from the Roman goddess of love and beauty, Venus.
Venus has been known to humans since ancient times, and it has been revered and revered in many cultures throughout history. In Roman mythology, Venus was the goddess of love, beauty, and fertility. She was also known as the protector of gardens and the guardian of travelers. The Romans believed that Venus was the mother of the Roman people, and she was often depicted as a beautiful woman with long flowing hair and a crown of flowers.
The Romans named the planet Venus after their goddess because of its bright appearance in the sky. Venus is the brightest planet in the solar system and is often visible in the early morning or late evening hours. It is also known as the "Morning Star" or the "Evening Star" due to its appearance in the sky at different times of the day.
In addition to its bright appearance, Venus is also known for its unique surface features and characteristics. It has a thick, toxic atmosphere made up of mostly carbon dioxide and nitrogen, with clouds of sulfuric acid. Venus also has the hottest surface temperatures of any planet in the solar system, reaching up to 864 degrees Fahrenheit (462 degrees Celsius).
Overall, the name Venus reflects the planet's bright appearance in the sky and its association with the Roman goddess of love and beauty. It is a fitting name for a planet that has captivated and fascinated humans for centuries.
When this procedure happens, the seeds are said to undergo sprouting procedure. L -1 EDTA , a atividade da α-amilase das sementes tratadas com B. Hence, the area of starch agar that represents the absence of starch is bigger and the concentration of brick-red precipitate is lower indicating the presence of small amount glucose. Transfer the seeds including the plumule and radicle into the howitzer. Do not use an Oxford Academic personal account.
Part 2 Determination of amylase activity in germinating barley by measuring the
Subtilis QM3, 10 8 CFU. Figure 3 Effect of B. Ensure the volume of each drop is approximately equal for each well. Mitigative effect of Bacillus subtilis QM3 on root morphology and resistance enzyme activity of wheat root under lead stress. In rice Oryza sativa , this difference was correlated with the level of incorporation of 35S-methionine into 25-60% ammonium sulphate precipitable material that was rich in amylase proteins.
Institutional account management For librarians and administrators, your personal account also provides access to institutional account management. The Plant Cell, v. Measure and record the length of radicle and plumule by utilizing the swayer. Copyright 1995, 1999 Academic Press Get help with access Institutional access Access to content on Oxford Academic is often provided through institutional subscriptions and purchases. Journal of Ecology, v. If you believe you should have access to that content, please contact your librarian.
Similarly, α-amylase activity of co-treated group 2 mmol. Put a spoonful of sand and 10 ml of distilled water into the mortar. Signed in but can't access content Oxford Academic is home to a wide variety of products. This authentication occurs automatically, and it is not possible to sign out of an IP authenticated account. QUANTITATIVE DATA Plate A boiled green bean seeds Home plate B soaked green bean seeds Plate C dried green beans seeds Change in length of the radicle, centimeter A± 0. Open Life Sciences, v. In vivo synthesis and turnover of α-amylase in attached and detached cotyledons of Vigna mungo seeds.
Release and activity of bound β-amylase in a germinating barley grain. The seeds were collected at different germination stages 0, 12, 24, 36, 48, 60 and 72 h for determination of α-amylase activity. Hypothesis: The higher the amylase activity, the higher the rate of seed sprouting which is indicated by the higher alterations in length of plumule and radicle. These changes are different from those of germinating seeds of many other plants, but similar to the germinating seeds of alfalfa, which belongs to the same tribe Trifolieae as clover. Then, the supernatant was discarded, and the cells were washed by sterile water three and resuspended in sterile water adjusting to OD 600 of 0.
Imbibition procedure causes the release of growing works gibberelin which stimulates the synthesis of amylase. Figure 1 Grain morphology and water content changes during seed germination. Journal of Plant Physiology, v. Now that you are familiar with the colour change reaction that occurs when starch and iodine are mixed together, you are ready to start your experiment. Bot Mag Tokyo 105, 167—170 1992. INVESTIGATING THE AMYLASE ACTIVITY OF GREEN BEAN SEEDS. Journal of Ecology, v.
Grind the mixture utilizing the stamp until it becomes watery mixture. Seeds: physiology of development and germination. Boil 5 green bean seeds. The outgrowth of plumule and radicle indicate that the seeds have germinated. Imbibition process causes the release of growth plant gibberelin which stimulates the synthesis of amylase. L -1 EDTA , α-amylase activity of seeds treated by B. In contrast, β-amylase activity was present in all seed stocks capable of 99 % germination, although the level was lower in seeds that grew slowly when germinated.
It indicates that the inhibition has been alleviated. Plant Physiology and Biochemistry, v. Amylase activity is affected by many factors such as temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators. The germination rate was calculated by continuously recording the number of germinated seeds for 72 h. The homogenate was collected in a centrifuge tube and centrifuged for 30 min at 10000 r. Em comparação com o grupo inibidor 10 mmol. Note the colour changes and record the data obtained.
Determination of amylase activity from germinated Syzygium cumini seed (jamun)
Text Preview Amylase is an enzyme found in the germinating seeds. Studying of the promotion mechanism of Bacillus subtilis QM3 on wheat seed germination based on β-amylase. Plant Signaling and Behavior, v. A taxa de germinação e a atividade de α-amilase de sementes de trigo foram significativamente aumentadas após a germinação com Bacillus subtilis QM3 neste estudo. Open Access Library Journal, v. At different germination times, the number and brightness of bands in Group B were different from those in the control group. All questions and space for answers are provided at the end of these prac notes.
Some societies use Oxford Academic personal accounts to provide access to their members. Advances in Microbiology, v. In order to explore the increase of germination rate of wheat seeds was related to α-amylase under the action of B. Thus, the seed weight increased quickly during the first 12 h of imbibition Phase 1 , after which the seed weight increases slowly from 12 to 24 h. Nitrate controls testa rupture and water content during release of physiological dormancy in seeds of Sisymbrium officinale L.
