Questions and Answers

What is the difference between lateral bud and compound bud in grapevine?

  • Compound bud is the first bud formed in the leaf axil during a specific season while lateral bud is not.
  • Compound bud has a primary bud and two secondary buds while lateral bud does not. (correct)
  • Lateral bud is formed in the leaf axil during a specific season while compound bud is not.
  • Lateral bud bears grapes while compound bud does not.

    • What is the effect of cytokinin on the formation of inflorescence primordia in grapevine?

  • Cytokinin has no effect on the formation of inflorescence primordia.
  • Cytokinin reduces the number of inflorescence primordia per bud.
  • Cytokinin is not necessary for the formation of inflorescence primordia.
  • Cytokinin increases the number of inflorescence primordia per bud. (correct)

    • What is a bearer shoot in grapevine?

  • A two-year-old shoot on one-year-old wood.
  • A one-year-old shoot on one-year-old wood.
  • A two-year-old shoot on two-year-old wood.
  • A one-year-old shoot on two-year-old wood. (correct)

    • What are anlagen and what is their role in the development of inflorescence primordia?

    <p>Anlagen are undifferentiated primordial tissue that can give rise to either bunch primordia or tendril primordia. Their role is to develop inflorescence primordia during the second phase of bud development.</p> Signup and view all the answers

    What is a bearer shoot and why are the basal buds of wine grape cultivars normally fertile enough to prune the shoots to short bearers?

    <p>A bearer shoot is a one-year-old shoot on two-year-old wood. The basal buds of wine grape cultivars are normally fertile enough to prune the shoots to short bearers because bud fertility (expressed as number of inflorescence primordia per bud) increases from the basal part of the shoot to the middle, and then decreases from the middle to the apical part of the shoot.</p> Signup and view all the answers
