Effects of different shading treatments on agronomic traits of 10 germplasm resources of Ophiopogon
The experiment took 10 germplasm resources of Ophiopogon bodinieri from different regions as research objects,and studied the effects of shading on agronomic traits,photosynthetic characteristics,stomata and leaf anatomy through different shading treatments.The membership function method was used.Combined with field experiments,the shade resistance differences between germplasm materials were comprehensively compared.and preliminary screening of suitable shade tolerance for planting in Chengdu was made resources Ophio-pogon bodinieri.The results are as follows:The plant height of the test material varies with the shade of the plant,and the plant height in-dex will increase in the appropriate shade;the materials with strong shade resistance,SAG-OJ-19002,SAG-OJ-19004,SAG-SY-19005,SAG-DZ-19007,SAG-XJ-19008,SAG-BQ-19010,The ramets of these varieties of also increase with time;the leaf length and leaf width of the test material increase with the increase of shading time;its water content(LWC)also increases with the in-crease of shading time.
