Study Notes
Types of Dormancy and Seed Factors
- Dormancy due to factors within an embryo is known as endogenous.
- Seed vigor is affected by time of storage, type of seed, and storage environment.
Plant Classification and Characteristics
- Deciduous plants are mostly grown in hilly areas.
- Vine means climbing/trailing plants with a herbaceous stem.
- Monoecious plants have male and female flowers/floral parts on the same plant.
Fruit Types and Development
- True fruits are developed from the ovary.
- Drupe fruits have all the three ovarian layers fused.
- Mango is a drupe fruit.
- Citrus is a special type of berry called hesperidium.
Binomial Nomenclature and Cultivar
- In binomial nomenclature system, the first name is always the generic name.
- Cultivar means cultivated variety.
Vitamin A and Health
- Vitamin A is effective against night blindness.
Statistical Analysis and Research Design
- A test of significance to compare treatment means is applied only if the probability value is less than the set value.
- Significance of data is indicated initially by analysis of variance.
- An outlier is a reading taken from a wrong sample.
- Generally, the number of blocks should not be less than three.
- A researcher can include a new experiment in an experiment that is already in progress using a split-plot design.
- Design selection for an experiment having same treatment combinations is based on the importance of one factor over the other.
Horticultural Practices and Crop Characteristics
- Grafting is commonly practiced in plants of the Cucurbitaceae family.
- Pepper is the most sensitive one to abiotic stresses among certain crops.
- Bitter gourd has the longest shelf life among certain crops.
- Garlic will produce large-sized cloves if exposed to cool weather during the bulb formation stage.
- Most potato genotypes do not form stolon and tubers at day and night temperature higher than 25 & 20 °C.
- Excessive humidity negatively affects flowering and thus affects seed yield.
- Frequent irrigation is required when warm and dry winds prevail.
- Loam soil is relatively fertile but not suitable for root crops.
- Bottle gourd is a short-duration crop and has a shallow root system.
- Yield in tunnel tomato is dependent on vegetative growth of plants before fruit set.
- Clay soils do not require frequent irrigation and fertilizer application but are not suitable for most vegetables.
- Phosphorus is unavailable to plants in highly acidic soils.
