[#678] Indicator plant for fluoride pollution is
Correct Answer

(B) Gladiolus

Explanation

Solution: The indicator plant for fluoride pollution is Gladiolus . The most widely used fluoride bioindicator is Gladiolus. This plant is showing typical fluoride injury. Varieties differ enormously in sensitivity and cultivation also seems to affect response. The use of Gladiolus plants was an effective biomonitoring technique for assessing the impact of atmospheric fluoride concentrations near a small-scale, poorly managed brick kiln in South Asia.

[#679] Chandra Shankara is a cross berween
Correct Answer

(D) COD × WCT

Explanation

Solution: Chandra Shankara is a cross between COD × WCT . Chandrasankara (COD × WCT) is a hybrid coconut variety. Hybrids are the intervarietal crosses of two morphological forms of coconut. They show earliness in flowering and give increased yield, higher quantity and better quality of copra and oil when compared to the parents.

[#680] Which fruit follows a double sigmoid curve
Correct Answer

(B) Fig

Explanation

Solution: Fruit follows a double sigmoid curve in Fig . A double-sigmoidal curve will generally need at least six parameters, two midpoints and slopes parameters each, a maximum value and an asymptotic final value after decay. An S-shaped or sigmoid curve is obtained upon plotting the total growth of a plant against a particular time interval. The double sigmoid growth curve of the fig shows the progression in fruit diameter and ethylene evolution during the three phases of fruit growth.
