Many friends have raised pitcher grass, but few have seen its seeds. Nepenthes is a dioecious plant. In order to produce seeds, it is necessary to have plants of two sexes. However, the number of female pitcher plants is small, so it is rare for them to produce seeds.
Characteristics of the seed of pitcher plant. The fruit of pitcher plant is capsule. The seed is very small and slender, fusiform to filiform. It is about 1cm in length and 1mm in width. It is made of wood. An embryo with a tiny protuberance in the middle. The seeds of pitcher grass are very light and easy to be carried away by the wind, so the seeds of pitcher plant are spread by wind. And its seeds are not rich in nutrient meat, so they are not attractive to animals. The survival time of pitcher seeds is not long, and the germination rate will be greatly reduced after one or two months. Therefore, the seeds of pitcher plants are not generally stored.
Want to know more about the information of pitcher grass (click to enter) the preservation of the seeds of pitcher plants. The seeds of pitcher plants are not resistant to preservation. It is said that some people use refrigerators to refrigerate (4 ℃) pitcher seeds for a year, but others say that they can only keep them for a few weeks at most, and even low temperature will accelerate the death of low-lying pitcher seeds. Therefore, the seeds of pitcher plants are generally not preserved and should be sown immediately after being obtained.
Because the seeds of pitcher grass are very small, it is better to use peat and other fine-grained cultivation media to avoid the seeds falling into the cracks. In order to make the seeds evenly spread on the substrate, the seeds can be mixed with a small amount of sand, and then sprinkled on the substrate. The substrate must be kept moist. At the same time, it also needs high air humidity. You can seal the mouth of the basin with preservative film and poke several holes.
The germination of Nepenthes seeds requires light, so it is helpful to germinate if placed in a bright place; however, it is not allowed to be directly exposed to sunlight, otherwise the high heat caused by strong light will kill the seedlings. Since pitcher can be divided into upland and and lowland pitcher, appropriate temperature should be provided according to the variety. It takes a long time to germinate, about a month. After germination, the air humidity can be reduced gradually, and the hole on the film can be expanded gradually. About half a year to a year later, the seedlings can be transplanted to avoid overcrowding.
