While this SNP did not explain all of the difference in detection between people, it provides support for the theory that genetic differences occur in olfactory receptors that lead people to be unable to smell these odorous compounds. Asparagus – a delicious green vegetable known for its tender spears – is one of the most flavorsome veggies to eat, and also extremely nutrient dense. A scale leaf is always present at the point of branching of the tendril. It is fleshy, non-green underground stem. [55] Small-scale studies noted that the "asparagus urine" odour was not produced by all individuals and estimates as to the proportion of the population who are excretors (reporting a noticeable asparagus urine odour after eating asparagus) has ranged from about 40%[56] to as high as 79%. Figure \(\PageIndex{1}\): Stem modifications: Stem modifications enable plants to thrive in a variety of environments. Certain compounds in asparagus are metabolized to yield ammonia and various sulfur-containing degradation products, including various thiols and thioesters,[67] which give urine a characteristic smell. Creepers . The weak sub-aerial stems are modified into following four types: It is a creeping stem with long internodes, running horizontally on the soil surface. Example: Asparagus, Ruscus.

Snyder, Harry. The various aerial modifications are as follows: Stem or its branches get modified into green thread like leafless structures called tendrils which are meant for climbing. Such a branch is known as the cladophyll. Asparagus was also corrupted in some places to "sparrow grass"; indeed, John Walker wrote in 1791 that "Sparrowgrass is so general that asparagus has an air of stiffness and pedantry". [18], Only young asparagus shoots are commonly eaten: once the buds start to open ("ferning out"), the shoots quickly turn woody.[19].
