Horticulture: What Do You Know About Pomology? Trivia Quiz

The correct answer is "A and C both". The availability of darkness and etiolation both contribute to rooting in layering. Darkness helps promote root growth by stimulating the production of auxins, which are hormones that encourage root development. Etiolation, on the other hand, refers to the process of plants growing in low light conditions, causing elongated and weak stems. This condition can make it easier for plants to root in layering, as the stems are more flexible and can be easily bent and buried in the soil to promote root growth.

All the above options (glycerol, dimethyl sulphoxide, and DMSO) are commonly used as cryoprotectants. Cryoprotectants are substances that are added to cells or tissues to protect them from damage during freezing and thawing processes. Glycerol, dimethyl sulphoxide, and DMSO are all known for their ability to prevent ice crystal formation and maintain the integrity of cells and tissues during cryopreservation. Therefore, all of these options can be considered as commonly used cryoprotectants.

High-density planting refers to a planting technique where plants are grown at a higher density than traditional methods. This technique allows for increased productivity and efficient use of land. The given answer states that high-density planting was first established in Apple in England. This suggests that England was one of the pioneers in adopting this technique for apple cultivation. However, without further context or information, it is difficult to provide a more specific explanation.

Benzaldehyde is the correct answer because it is a volatile compound commonly found in almonds. It is responsible for the distinct aroma and flavor of almonds.

The term "markers assisted selection" was first used by Beckmann and Soller. This means that both options A and C are correct.

Post set fruit drop is a major problem in mangoes. This means that after the fruit has initially set on the tree, it may drop prematurely before reaching maturity. This can be caused by various factors such as environmental conditions, nutrient deficiencies, pests, diseases, or hormonal imbalances. Understanding and addressing these factors is important in order to prevent or minimize fruit drop and ensure a successful mango harvest.

The yellow-green color of avocado is due to the presence of lutein and zeaxanthin. These are two types of carotenoid pigments that are responsible for the yellow coloration in many fruits and vegetables. Lutein and zeaxanthin are also known for their antioxidant properties and their potential benefits for eye health. Therefore, the presence of these pigments in avocados not only contributes to their vibrant color but also adds to their nutritional value.

The two arm kniffin system is used in passion fruit training. In this system, two main arms are trained along a wire, with the fruiting canes growing vertically from these arms. This allows for better distribution of sunlight and air circulation, promoting healthy growth and fruit production. The two arm kniffin system is commonly used in vine crops like passion fruit to maximize yield and manage plant growth effectively.

Smudging is a technique used in horticulture to induce off-season flowering. It involves the burning of certain materials, such as sulfur or chemicals, to create smoke. The smoke produced by smudging contains compounds that can stimulate the plants' hormonal system, triggering the process of flowering even when it is not the natural flowering season. This technique is commonly used in commercial agriculture to extend the availability of certain crops or to produce flowers out of season for decorative purposes.

Cleavage polyembryony is a type of asexual reproduction where multiple embryos are formed from a single fertilized egg. This phenomenon is found in coconut plants. In coconut, the fertilized egg divides into multiple embryos, each of which develops into a new individual. This process results in the production of multiple offspring from a single parent plant.

The term 'Organic' was first used by Northbourne.

The correct answer is "Accessory tissue." In an apple, the fruit flesh develops from the accessory tissue. This tissue is responsible for the formation of the edible part of the fruit, which surrounds the seeds. The accessory tissue is derived from the ovary wall and undergoes changes during fruit development, resulting in the juicy and fleshy texture of the apple.

ISO 9000 is a set of international standards that focuses on quality management. It provides guidelines and criteria for organizations to ensure that their products and services consistently meet customer requirements and enhance customer satisfaction. ISO 9000 emphasizes the importance of implementing quality management systems, continuous improvement, and customer focus. Therefore, the correct answer is quality management.

Gregarious flowering refers to the phenomenon where multiple flowers bloom together in a cluster or group. Among the given options, apple trees are known to exhibit gregarious flowering. This means that multiple apple blossoms will bloom together on the same branch or tree, creating a visually stunning display. Quince, pear, and peach trees may also have clusters of flowers, but apple trees are particularly known for their gregarious flowering habit.

Peach is an amenable fruit crop for meadow orcharding because it is well-suited to growing in open, sunny areas with good air circulation. Meadow orcharding involves planting fruit trees in grassy meadows, and peaches thrive in this type of environment. They require full sun to produce sweet and juicy fruits, and the open space allows for better pollination and reduces the risk of diseases. Additionally, peaches have a shallow root system that benefits from the well-drained soil typically found in meadows. Overall, peach is a suitable choice for meadow orcharding due to its adaptability to the specific conditions of this cultivation method.

Endogenous dormancy refers to the type of dormancy that is inherent within the seed or bud itself. In the case of grapes, they exhibit endogenous dormancy, which means that the dormancy period is regulated by internal factors within the grape seeds or buds. This dormancy helps protect the seeds or buds from germinating or growing prematurely, allowing them to survive unfavorable conditions until the right environmental cues trigger their growth and development.

Hypogeal germination is a type of seed germination where the cotyledons remain below the ground after germination. In the case of a peach, the cotyledons stay underground while the stem and leaves emerge above the soil surface. This type of germination allows the seedling to establish a strong root system before exposing the photosynthetic organs to the external environment.

Mandarins are a type of citrus fruit that typically flowers three times a year. This means that they have multiple blooming periods throughout the year, allowing for a more continuous harvest. This is in contrast to other citrus fruits like grapefruits and lemons, which typically have one or two flowering periods per year. Therefore, mandarins are the correct answer as they are known for their ability to flower three times in a year.
