Hypocotyl - an overview | ScienceDirect Topics
网页The hypocotyl is the next organ after the radicle to emerge from the seed (Fig. 2). This pre-emergence phase is critical to enable the seedling to reach sunlight to commence photosynthesis. Canola exhibits epigeal germination, which restricts the sowing of seed to depths not exceeding the maximal length of the hypocotyl (Rebetzke et al., 2007).

网页The hypocotyl is the part of a seedling that connects the cotyledons (seed leaves) to the root system, serving as a crucial transitional zone during germination and early growth. It plays an essential role in the development of the plant, as it elongates to push the cotyledons above the soil, allowing for better light exposure and photosynthesis.
