Problem 199 - Objective Biology for NEET

Question

Assertion: Ethylene increases the yield in cucumber. Reason: Ethylene promotes female flower in cucumber.

Step-by-Step Solution

Answer

Yes, Ethylene increases the yield in cucumber because it promotes the production of female flowers, which can turn into fruits, therefore, increasing the yield.

Step 1: Understanding the Role of Ethylene

The first step is understanding the role of Ethylene in plants. Ethylene is a plant hormone that has a variety of functions. It's involved in many growth and development processes, including fruit ripening and flower sex differentiation. In the case of cucumbers, it promotes the production of female flowers.

Step 2: Understanding Yield In Cucumber Plants

The yield of cucumber plants is based on the number of cucumbers that are produced. Female flowers in cucumber plant have the potential to generate fruits. Hence an increased number of female flowers increases the potential yield from a plant.

Step 3: Connecting Ethylene to Yield

Now to tie these facts together: Since initiating female flowers can potentially increase the yield in cucumber, and Ethylene promotes female flowers, it can be deduced that Ethylene increases the yield in cucumber.
