Newhall navel orange seedlings with or without thorns

I don't know, you can check it out.

Navel orange saplings are generally thornless. Navel orange is a mutated orange that, unlike ordinary oranges, loses the barbed properties inherited from grapefruit, so it usually has no barbs, and navel oranges also have no seeds, and are formed by combining ripe fruits and immature small fruits, and are mainly propagated by cuttings.

1. No

Navel orange saplings are usually thornless. Orange is a new variety of citrus in the family Rutaceae that was bred by crossing citrus and grapefruit, so it inherits the characteristics of thorny branches from pomelo, but navel orange is a mutated orange variety that does not inherit this characteristic of pomelo itself.

2. Plant characteristics

The orange tree belongs to the small tree or shrub of the citrus genus of the Rutaceae family, its branches generally have thick and long spines, the petioles have short hairs, relatively loose, and the leaves are obovate or oval in length about 2-3 cm, while the navel orange is a subspecies, which is characterized by a small unripe fruit embedded in a large ripe fruit.

3. Reproduction method

Navel orange was first a mutated orange tree that appeared due to accident in 1820, which had no seeds, so it could only be propagated by cuttings, so in general, all navel orange varieties that have not been artificially improved have the same traits as the original navel orange.

4. Planting conditions

Navel oranges are not much different from oranges in terms of planting conditions and maintenance conditions, both are suitable for growth and development in a relatively warm and humid environment, but they can also tolerate a certain amount of cold, it is best to stabilize between 15-35 degrees Celsius, ensure sufficient light, watering and fertilizing moderately, navel oranges can grow healthily.

Yes, Newhall navel oranges are native to the United States, and are derived from the buds of Washington navel oranges in Duarte, California, USA, and were introduced in China in 1978. Newhall grows vigorously, with an open crown or a round head. The treetops are short and dense with dark leaves, which bear fruit slightly later than the Ponna and Robertson navel oranges.

The fruit is oblong or short oval, orange-red, beautiful, and weighs 250 350 grams in a single fruit, and weighs up to 750 grams. The fruit shape index was mostly around, and the Newhall (No. 2) introduced from Spain was slightly longer than the Newhall (2 8) introduced from the United States, and the fruit shape was slightly earlier.

The top of the fruit is slightly convex, with an umbilicus, and most of them are closed. The skin is smooth, the skin is centimeters thick, it is difficult to peel off, and it has a clear fragrance.

Your question should be why Newhall navel oranges don't bloom. The reason is that unreasonable fertilization causes excessive vegetative growth, inhibits reproductive growth, and leads to no differentiation in the flower bud differentiation stage of navel orange.

Newhall navel oranges are native to the United States and are derived from the buds of Washington navel oranges in Duarte, California, USA. It was introduced in China in 1978 and is widely cultivated in Chongqing, Jiangxi, Sichuan, Hubei, Hunan, Guangxi and other provinces, municipalities and autonomous regions. Newhall navel orange is a fresh-selling variety with beautiful appearance, excellent flesh quality and good commerciality.

Newhall grows vigorously, with an open crown or a round head. The treetops are short and dense, with dark leaves, and they bear fruit slightly later than the Ponnavel and Robertson navels.
