The question asks to identify the coffee species that is self-pollinating (autogamous). This requires knowledge of the reproductive characteristics of common coffee species.
C) Arabica is the coffee species known for being self-pollinating (autogamous). This characteristic contributes to its genetic stability and makes it easier to cultivate in certain environments without relying heavily on external pollinators.
The question asks for the ideal altitude range for Arabica coffee cultivation. This requires knowledge of the specific environmental requirements for Arabica coffee plants, particularly concerning altitude.
C) 600 to 2000 metres above sea level. Arabica coffee thrives in high-altitude regions, typically between 600 and 2000 metres (2000 to 6500 feet) above sea level. These altitudes provide the cool, subtropical climate, distinct wet and dry seasons, and rich volcanic soils often preferred by the plant, which contribute to its superior quality and flavor.
The question asks about the typical altitude range for Robusta coffee cultivation. To answer this, one needs to recall the environmental requirements for different coffee varieties, specifically Robusta.
Correct Option: A) Sea level to about 800 metres is the typical altitude range for Robusta coffee cultivation. Robusta is a hardier plant that can withstand warmer temperatures and higher humidity, making it suitable for lower elevations.
The question asks to identify the coffee variety typically grown at higher altitudes in India. We need to recall the characteristics and growing conditions of the main coffee types, Arabica and Robusta.
C) Arabica is the coffee variety generally grown at higher altitudes in India due to its preference for cooler temperatures and specific climatic conditions found at elevated regions.
The question asks for the ideal temperature range for Arabica coffee cultivation. This requires knowledge of the specific environmental requirements for this coffee variety.
D) 15°C to 24°C is the ideal temperature range for Arabica coffee cultivation. This range supports optimal growth, flowering, and fruit development, leading to high-quality beans.
The question asks for the ideal temperature range for Robusta coffee cultivation. To answer this, we need to recall the specific agro-climatic requirements for Robusta coffee.
Correct Option: D) 24°C to 30°C is the ideal temperature range for Robusta coffee cultivation. Robusta coffee is more heat-tolerant than Arabica and thrives in warmer, humid environments, typically at lower altitudes.
