Embodiment Construction

[0022] 1. Embodiment 1 "Jaguar No. 3" is a lawn type tall fescue variety with high heat resistance. Select high-quality "Jaguar No. 3" seeds and sow them in pots equipped with ordinary sand, clay and nutrient soil (volume ratio 1:3:3), and cultivate them at room temperature for 18 days. , the nighttime temperature is 30±0.5°C, and the light quantum is 150 μmol m -2 the s -1 , cultivated in an artificial climate box with a relative humidity of 70% for 3 days. No nutrients were applied during cultivation. Spray a small amount of water the next day before the seeds emerge, water the plants once every other day when they are cultivated at room temperature after emergence, and water once a day when they are under high temperature stress. Randomly collect and weigh 0.1 g of healthy leaves cultivated under normal temperature and high temperature stress, wipe off the surface dirt, cut them into pieces, put them in a mortar, add a small amount of quartz sand and grind them into a ho...

Abstract

The invention relates to a method for fast identifying the meadow type high fescue heat-proof quality in the field of cool quaternary type meadow resistance identifying biology technology. It puts the best seed of the meadow type high fescue species in the basin with the sand, clay and nutritious soil (the volume ratio is 1:3:3), and breeds it for 18 days at normal temperature, wherein part plant moves to the artificial climate case with the temperature of 35+ / -0.5 deg. in daytime and the temperature of 30+ / -0.5 deg. in dark time with the optical photon 150-200 mumolm<-2> s<-1> and the percentage humidity 65-70% for three days. It adds non-nutrients during the breeding course. It separately collects the meadow type high fescue health leaf at normal temperature and the high temperature and measures the chlorophyll a and b content of unit weight of the leaf tissue.

Description

1. Technical field [0001] The invention belongs to the technical field of cold-season turfgrass resistance identification biotechnology, and in particular relates to a new method for quickly identifying the heat resistance of turfgrass tall fescue. 2. Background technology [0002] Lawn-type tall fescue (Festuca arundinacea) is a perennial herb of the genus Festuca in the Gramineae family. It grows in clusters, has well-developed fibrous roots, strong plants, and has wide adaptability. The best grass species (Xu Sheng et al., 2004). Continuously improving varieties through breeding, the current turf-type tall fescue is cold-resistant, heat-resistant, trampling-resistant, and disease-resistant, acid-resistant, salt-alkali-resistant, drought-resistant, water-logging resistant, light-loving and shade-tolerant, resistant to pruning, and has a long green period. , management is convenient, and the cost of building flats is low, so it is widely used in urban greening, football fi...
