Application of NAA and 2,4-D has been used to make the pineapple plant produce fruits throughout the year. This is because these hormones help in inducing flowering in the plant.
Explanation:
Pineapple is a tropical fruit that is native to South America. Under natural conditions, pineapple plants are difficult to blossom, and they only produce fruits once a year. This is because the plant requires specific environmental conditions, such as long days and warm temperatures, to initiate flowering.
To overcome this limitation, plant hormones such as NAA (naphthaleneacetic acid) and 2,4-D (2,4-dichlorophenoxyacetic acid) are used. These hormones are synthetic versions of the natural plant hormone auxin, which controls plant growth and development.
The application of NAA and 2,4-D helps in inducing flowering in the pineapple plant by promoting the growth of the floral meristem. This leads to the production of more flowers, which eventually develop into fruits. The use of these hormones allows the plant to produce fruits throughout the year, irrespective of the environmental conditions.
Conclusion:
The application of NAA and 2,4-D has been used to make the pineapple plant produce fruits throughout the year. These hormones help in inducing flowering in the plant, leading to the production of more fruits. This has helped in increasing the yield of pineapple crops and making them available throughout the year.
