Assertion & Reason +4 −1

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).

Assertion (A) : The primary cause of graft incompatibility in interspecific Cucurbita sp is the occurrence of hormonal imbalances between auxin and ethylene, in the root system followed by tissue disintegration

Reason (R) : The basipetal flow of excess auxin at graft union block the formation of ethylene, consequently leading to cellular juvenility.
