Step 1: Understanding the Concept:
Different fruit crop cultivars are grown for specific culinary and processing uses based on their chemical composition, such as sugar and starch content.
Similarly, fruit crops differ in their tolerance to environmental stresses like soil salinity, which affects water absorption and ion toxicity.
Step 2: Detailed Explanation:
Let us analyze each statement individually:
1. Statement I describes the Nendran banana.
Nendran is a popular French Plantain cultivar grown extensively in Kerala, India.
It is characterized by large, firm, and starchy fruits.
Because of its high starch content and low sugar-to-starch ratio when unripe, it is the primary cultivar used to make traditional banana chips.
Thus, Statement I is correct.
2. Statement II describes salt tolerance in grapes and ber.
Ber (Ziziphus mauritiana) is an extremely hardy, drought-tolerant fruit crop that can grow in arid, saline, and alkaline soils.
In contrast, grapes (Vitis vinifera) are highly sensitive to salinity, particularly to chloride and sodium ion toxicity, which can cause leaf burn and reduce yields.
Therefore, ber is significantly more salt-tolerant than grapes, making Statement II incorrect.
Therefore, Statement I is correct, and Statement II is incorrect.
Step 3: Final Answer
Statement I is correct, but Statement II is incorrect.
