Question

C:N ratio concept for flower bud initiation was suggested by Kraus and Kraybill (1918) in which of the following crop ?

• A. Potato
• B. Tobacco
• C. Onion
• D. Tomato

Hint:

Kraus and Kraybill's work (1918) is a classic milestone in plant physiology.
Always associate their names and the C:N ratio concept with the Tomato crop.

Answer 1

The Correct Option is D

The concept of the Carbon to Nitrogen (C:N) ratio for flower bud initiation was suggested by Kraus and Kraybill (1918) in the crop Tomato. Let's understand this in more detail:

1. Significance of C:N Ratio: The C:N ratio is a crucial factor in plant development, especially in the initiation of flowering. A balanced C:N ratio often leads to successful flower bud initiation, as the appropriate levels of carbon and nitrogen are vital for plant growth and development.
2. Kraus and Kraybill's Contribution: In 1918, researchers Kraus and Kraybill studied the effects of nutrient balance on plant growth and development. They concluded that the C:N ratio played a vital role in flower bud initiation, especially in tomatoes.
3. Analysis of Options:
   • Potato: The primary research by Kraus and Kraybill was not focused on potatoes.
   • Tobacco: Although nutrient balance is essential for tobacco, this study did not highlight tobacco in relation to C:N ratios for flowering.
   • Onion: Onions were also not the focus of the original study by Kraus and Kraybill.
   • Tomato: This was the crop specifically studied by Kraus and Kraybill to establish the relationship between the C:N ratio and flower bud initiation.
   The research findings highlighted the role of nutrient management in tomato cultivation and how adjusting the C:N ratio could promote healthy flower development.
4. Conclusion: Based on the historical research by Kraus and Kraybill, the correct answer to the question is Tomato. This research has been fundamental in understanding the importance of nutrient ratios in horticultural practices.
