Question

callus formation, which occurs during storage, ______.
a. makes it difficult for the cuttings to root under moist conditions when transplanted outdoors
b. can be an benefit if the cuttings will not be transplanted outdoors until the second season
c. is an advantage when cuttings are placed outdoors for rooting under drying conditions
d. should be monitored and avoided if possible in order for the plant to grow well outside

Explanation:

To solve this, we analyze each option:

• Option a: Callus formation typically aids rooting, so this is incorrect.
• Option b: If cuttings aren’t transplanted until the second season, callus (a mass of undifferentiated cells) can help in developing a stronger root system later, so this is a benefit.
• Option c: Callus helps in moist conditions, not drying ones, so this is incorrect.
• Option d: Callus isn’t something to avoid; it’s part of the natural process for rooting, so this is incorrect.

Answer:

b. can be an benefit if the cuttings will not be transplanted outdoors until the second season
