Super big pumpkin weighs more than 821 kg

Pumpkin by Chris Stevens weighing over 821,2428kg is being performed by NewYork botanical garden staff. Scientists think they can explain why this pumpkin can grow to a giant size without cracking.

The researchers successfully simulated the mathematical model of the stress tolerance limit of this pumpkin.

In its existence and development cycle, the giant pumpkin fruit will be affected by stresses greater than normal, ie the force acting on the surface of an area unit in the direction that will make it a giant pumpkin grow bigger.

' The weight of pumpkins creates tensile stress, pulls out cells and speeds up growth, ' says David Hu, a mechanical engineer working at The Georgia Institute of Technology, Atlanta, USA. He and his colleagues have published research results in a Peer-reviewed journal Science.

This study is not merely a reference to the story of a giant pumpkin weighing nearly 821,2428kg (more than 821kg), which was recorded in the Guinness Book of World Records in October 2010, but also aimed at wider problems in plant survival and development, such as how tissues cope with stress, according to David Hu.

All of the giant pumpkins come from a single variety, The Atlantic Giant seed, which lasts and grows until its harvest lasts longer than normal pumpkin varieties. At first it has a round shape, but when it reaches a weight of about 99,792kg (more than 99 kg), it starts flattening its shape by weight, to eventually become a giant pumpkin.

The question for scientists is why with such a huge size that zucchini is not cracked, David Hu's team put ordinary squash in the laboratory to measure maximum stress. that it tolerates before it breaks. The researchers then simulated a mathematical model of the stress tolerance limits of these fruits. David Hu said that it is the resin of pumpkin or a certain deformation mechanism that helps this giant pumpkin distribute evenly so it can grow up to 22.68 kg (more than 22kg) each the day without breaking.

Experts working at the New York Botanical Garden, where the world's largest pumpkin cut last weekend, said they hoped to harvest a pumpkin weighing about 907.2kg in a few years. half.

Pumpkins can withstand great stress before they are cracked. A kind of internal coping mechanism has allowed pumpkins to grow to huge sizes, according to scientists.
