Peduncle<\/strong><\/h3>\n\n\n\nThe peduncle, or stem, is the part of the pumpkin that one may use to pick it up from their neighborhood pumpkin patch. From an anatomical standpoint, the peduncle links the pumpkin to the vines.<\/p>\n\n\n\nA pumpkin's peduncle links the pumpkin to its vines.<\/figcaption><\/figure>\n\n\n\nA giant pumpkin\u2019s peduncle is a critical part of an oversized pumpkin. \u201cYou want to have sufficient length on that,\u201d said Huber. Otherwise, if the peduncle is not long, or sturdy enough, it may lead to stem stress, where the pumpkin breaks itself off of its own vine. <\/p>\n\n\n\n
The peduncle to the fruit is propped up above the ground to prevent vine stress, so that the vine is elevated to account for the future growth of the fruit, Huber said.<\/p>\n\n\n\n
The Pumpkin<\/strong><\/h3>\n\n\n\nThe pumpkin, or the fruit on the plant, can be described as a \u201csink,\u201d Hernandez said. The pumpkin will store nutrients and water from other parts of the plant, such as the leaves. <\/p>\n\n\n\n
If there are multiple \u201csinks\u201d on a plant, the food and water will be distributed somewhat evenly across these multiple pumpkins. However, if there is only one pumpkin, or very few in a patch, it can absorb these nutrients and grow large. <\/p>\n\n\n\nHuber's pumpkin weighed 196 pounds and placed ninth at the Great Pumpkin and Watermelon Weigh-Off. <\/figcaption><\/figure>\n\n\n\nBecause of this, growing a great pumpkin requires navigating this source-sink relationship, Huber said. Strategies may include cutting off new fruits to help the one pumpkin amass nutrients. This can be especially important because a pumpkin can grow 50 pounds per day at the peak of its growth, said Huber. <\/p>\n\n\n\n
But more nutrients and water is not always better, Huber said. <\/p>\n\n\n\n
If a pumpkin receives too much water, it can split. A grower may intentionally leave extra pumpkins in the patch temporarily as a reservoir to absorb this extra water, especially if they know a storm is coming. <\/p>\n\n\n\n
What does it feel like when the pumpkin splits for the grower? \u201cIt\u2019s devastating,\u201d Huber said. \u201cIt can be a stressful hobby.\u201d<\/p>\n\n\n\n
Leaves<\/h3>\n\n\n\n When one imagines a pumpkin, she may think of rows of orderly pumpkins at the neighborhood pumpkin patch. But these picture-perfect pumpkins lack a valuable asset: their leaves. <\/p>\n\n\n\nLeaves function as important \"sources\" for the pumpkin, which is the \"sink.\"<\/figcaption><\/figure>\n\n\n\nA giant pumpkin is surrounded by leaves that it works in tandem with to fuel its growth. These leaves, shaped almost like a martini glass, emerge from vines that run throughout the patch. The pumpkin\u2019s leaves are \u201csources\u201d because this is the spot where the plants generate \u201cfood harvested from the sun\u201d (i.e., photosynthesis), said Hernandez. <\/p>\n\n\n\n
When the chloroplasts in these leaves create glucose, the leaves then diverts this energy to a sink (e.g., the pumpkin) for storage. This energy is vital for the pumpkin to absorb to grow large. <\/p>\n\n\n\n
Vines and Roots<\/h3>\n\n\n\n Surrounding this pumpkin aboveground are its vines. The pumpkin has one main vine, and then smaller vines that branch off of it, similar to backroads branching off of a major highway. <\/p>\n\n\n\n
If one could peer below ground near the pumpkin, they would see an extensive root system. These roots and vines operate in tandem, said Huber. Vines can provide support for a pumpkin and help stabilize it in its spot. <\/p>\n\n\n\n
If a storm comes along, the pumpkin is less apt to be displaced if its vines are holding it in place. Besides support, the leaves on the vine each try to form a root, Huber said. <\/p>\n\n\n\nVines surround the giant pumpkin and provide it with support.<\/figcaption><\/figure>\n\n\n\nThese roots are critical for transporting needed nutrients to the pumpkin from underground. To facilitate the pumpkin\u2019s growth, growers will bury the vine, Huber said. By packing dirt on top of the vine, the root may be more likely to form. The goal is to form a \u201cgiant root system\u201d to facilitate the growth of this \u201cgiant plant,\u201d Huber said. <\/p>\n"},"excerpt":{"rendered":"
