Problems solved by technology

The research of domestic scholars is also only by using some known effective germination stimulators and haustorium inducers of root parasitic plant seeds, such as plant hormones (gibberellins, auxins, cytokinins, etc.) Allergens, p-benzoquinone, etc.) stimulate the germination of Cistanche seeds, but an effective method that can improve the seed germination and inoculation rate in the large-scale production and planting of Cistanche has not been found yet.
[0008] In order to solve the contradiction between the growing market demand and the reduction of wild Cistanche resources, domestic scholars have carried out a lot of research work on the artificial planting of Cistanche. generally low rate

Embodiment 1

[0036] Embodiment 1, screening the higher Cistanche seeds of maturity and vigor

[0037] 1. The distribution of seed diameter in different parts of the inflorescence

[0038] The mature inflorescence of Cistanche deserticola is equally divided into upper, middle and lower parts (from the top of the inflorescence down to 1 / 3 of the length of the inflorescence, recorded as the upper part of the inflorescence, and from the bottom of the upper part of the inflorescence down to 1 / 3 of the length of the inflorescence. / 3, recorded as the middle part of the inflorescence, starting from the bottom of the middle part of the inflorescence down to the bottom of the inflorescence, recorded as the lower part of the inflorescence), and then set them with three sections of white nylon mesh bags (the mesh size is greater than 70, to prevent the seeds from falling to the ground). Live in the upper part of the inflorescence, the middle part of the inflorescence, and the lower part of the inflores...

Abstract

The invention discloses a method for screening cistanche seeds. The invention discloses a method for collecting seeds of Cistanche deserticola, which comprises the following steps: collecting seeds with a diameter of 0.6-1.0 mm from seeds in the middle of the inflorescence and / or in the lower part of the mature inflorescence of the cistanche deserticola. The invention effectively solves the problems of poor seed quality and low germination rate in the large-scale planting process of Cistanche deserticola.

Description

technical field [0001] The invention relates to a method for screening cistanche seeds, belonging to the field of biotechnology. Background technique [0002] Cistanche deserticola (Cistanche deserticola Y.C.Ma) is a perennial holoparasitic herbaceous plant belonging to the family Orobanchaceae of the genus Cistanche. The classification of the genus Cistanche has not been unified in my country, and many scholars often divide the species and varieties of Cistanche according to the morphological differences of Cistanche in different places of origin and in different growth environment conditions. In the 69th volume of "Flora of China", the genus Cistanche in my country was identified as five species and one variety, namely Cistanche, Cistanche (C.sinensisG.Beck), Cistanche salsa [C.salsa (C.A.Mey. G.Beck], Cistanche deserticola [C.tubulalosa (Schenk) Winht] and Cistanche deserticola in Lanzhou (C.lanzhouensisZ.Y.Zhang), the suspected species is Cistanche deserticola mongolica ...
