Embodiment Construction

[0027] The invention provides a method for in vitro germination culture of bellflower pollen to measure pollen viability. On the basis of determining the in vitro germination culture system of bellflower pollen, the bellflower pollen is cultured in vitro, and the germination rate of pollen and the number of pollen tubes are measured. Growth conditions, reliable and effective determination of bellflower pollen vigor. The present invention will be described in further detail below in conjunction with the accompanying drawings, which are explanations rather than limitations of the present invention.

[0028] 1. Collection of bellflower pollen

[0029]Platycodon pollen was collected from the 2-year-old platycodon group in the medicinal botanical garden of Shangluo Xiangju Pharmaceutical Company in Shaanxi in mid-July 2008. The collection method is: select robust plants with normal development and no pest damage, and collect them at the flowering stage from 7:00 to 8 am in the morn...

Abstract

The invention discloses an in-vitro pollen germination liquid medium of balloon flower (platycodon grandiflorum (Jacq.) A. DC) and a method using same to determine the pollen viability thereof, particularly a method for reliably and effectively determining the pollen viability of the balloon flower through the in-vitro pollen culture of the balloon flower after the in-vitro pollen germination culture system is determined. The in-vitro pollen germination liquid medium is characterized by using distilled water as the solvent with the pH value being 5.8, wherein, the distilled water comprises the following components: ME3, BK, 100g / L sucrose and 150g / L PEG (polyethylene glycol). The method comprises the following steps: evenly scattering the pollen over the in-vitro pollen germination liquidmedium, and culturing at a constant temperature (30 DEG C) under the lighting condition; in-vitro culturing for 1.5h and determining the pollen germination rate and the pollen tube lengths which reflect the pollen viability, particularly, counting the pollen germination rate by the pollen germination standard that the pollen tube length is larger than the pollen particle diameter, and measuring and averaging the pollen tube lengths, wherein, the pollen germination rate reflects the proportion of the viable pollen, and the growth condition of the pollen tube of the in-vitro cultured pollen reflects the physiological condition of the pollen particles.

Description

technical field [0001] The invention belongs to the technical field of measuring plant pollen vigor, and in particular relates to a liquid culture medium for in vitro germination of bellflower pollen, and a method for measuring pollen vigor based on the liquid medium by utilizing the in vitro germination culture of bellflower pollen. Background technique [0002] Campanulaceae (Platycodon grandiflorum (Jacq.) A.DC) belongs to Campanulaceae, Platycodon genus, is a perennial dicotyledonous herbaceous plant, and is a plant with both medicine, food and ornamental functions. The root of Campanulaceae can be used as medicine, and its main active ingredient is saponin, which has a wide range of pharmacological activities such as antitussive, anti-inflammatory, lowering blood pressure, lowering blood sugar, weight loss, anti-tumor, and improving human immunity. Platycodon grandiflora tender seedlings and roots can be eaten. It is a common vegetable in Northeast my country and East A...
