    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.
