The two fruits most afraid of being fat are pitaya and lemon. Pitaya is very common in our daily life, especially the red pitaya, which has very high nutritional value and very low calorie. It is also a good helper to lose weight and can quietly reduce the weight to double digits.

Morphological characteristics of pitaya

Pitaya is a perennial climbing succulent plant. The plant has no main roots, and its lateral roots are widely distributed in shallow soil. At the same time, there are many aerial roots that can climb and grow. Rhizomes are dark green, stout, 7 meters long, 65,438+00 ~ 65,438+02 cm thick, flat with 3 sides and wavy sides. Climbing roots grow on stem nodes and have three growth edges, so they can climb on other plants. Each stem node has three ribs.

There are a large number of multi-bud and mixed bud primordia in buds, which can be extracted into leaf buds and flower buds. In the early stage of flower bud development, it can be transformed into leaf bud under suitable temperature conditions, and the apical tissue of vigorous branches can also be extracted into flower bud under suitable conditions.

Due to long-term growth in tropical desert areas, its leaves have degenerated, and the photosynthetic function is borne by the stem. There are a lot of parenchyma cells filled with viscous liquid inside the stem, which is beneficial to absorb as much water as possible in rainy season.
