What does diploid watermelon triploid quadruple mean?

The chromosomes in the cells of an organism are multiplied, that is, each chromosome has one or more chromosomes that are identical in morphological structure and genetically identical to it. Any biological individual that contains two sets of chromosomes in a somatic cell is called diploid and can be represented by 2n; Any biological individual with three sets of chromosomes in somatic cells is called triploid, which can be represented by 3n; Any biological individual that contains four sets of chromosomes in a somatic cell is called tetraploid and can be represented by 4n. The vast majority of organisms are diploid, and there are also polyploid.

Ordinary watermelons are diploid, only after treatment does tetraploid watermelon appear, tetraploid watermelon and diploid watermelon hybridization, so that the genetic genes of watermelon appear only three sets of chromosomes, and the genetic material appears chaotic, resulting in non-fruiting, only triploid seedless watermelon appears.

Triploidy

Watermelon is a triploid plant. The cultivation process of seedless watermelon: 1. Treatment of ordinary watermelon with colchicine makes the chromosomes of diploid watermelon plants tetraploid (4n 44).

2. Use the 4ploid watermelon plant as the female parent (demasculated during flowering) and the diploid watermelon plant as the male parent (take its pollen to give the 4ploid pistil) for crossing, so that the triploid seeds can be produced on the 4ploid watermelon plant.

Hello dear! Thank you for your patience, according to your problem description: triploid watermelon refers to its chromosome number is triploid, that is, its nucleus contains 3 sets of chromosomes.

Compared with diploid ordinary watermelon, triploid watermelon has the following characteristics:1Sweeter :

The flesh of triploid watermelon is more delicate, crisp and less fibrous. 3.High nutritional value:

Triploid watermelon is rich in a variety of nutrients, such as vitamin C, carotene, lycopene, etc., which are beneficial to human health. 4.Lower yields:

Because triploid watermelons need to consume a lot of energy and nutrients in the process of growth and development, their growth rate is slower and the yield is lower due to empty sales. 5.**Higher:

Due to the long growth cycle and low yield, triploid watermelon** is generally much higher than ordinary watermelon.

Hello! We're glad to answer your questions! <>

2. Larger body size: triploid watermelons are generally larger than diploid watermelons, and the average fruit weight can reach more than 20 kilograms. 3. Higher nutritional value:

Triploid watermelon pulp contains more vitamin C, vitamin B1, B2, B6, as well as minerals such as potassium, magnesium, calcium, etc., which are beneficial to the human body. <>

4. Thin skin and few seeds: triploid watermelon has relatively thin skin and fewer grains, making it easy to eat. 5.

Long growth cycle: Triploid watermelons have a relatively long growth cycle due to the higher number of chromosomes and take longer to mature.

Triploid seedless watermelon is a medium-late maturing variety with a full growth period of 108 days and a fruit development period of 34 days. The plant growth is stable and the branching is average; The main vine is about 280 cm long, and the main whole thickness is about centimeters, and the internodes are about 9cm long; The leaves are medium-large, and the palmate leaves are carved and lobed; The first female flower is born around 10 nodes, and the female flowers are spaced 5-6 nodes apart; It is easier to sit on melons, and the average weight of a single melon is about 8 kilograms; The fruit shape is high and round, the green skin is covered with large and wide green flower strips, and the spacing of the bands is narrow and uniform; The flesh is bright red, fine and crisp, and it feels good; Thick skin, hard and tough, good storage and transportation resistance; The seeds are ovate, Y-shaped, light brown, with deep grooves on the surface, colored, and the 1000-grain weight is 65g, and the left and right parts are slightly dark brown.
