Through indoor window culture and dark culture, the creeping bentgrass 1 and its dwarf lines 16 13-0 1, 16 13-02 and/kloc-0 were obtained. 16 14-3, 3603, 3605-2, plant height, root length, leaf length, tiller number, biomass, leaf survival days, leaf yellowing rate, leaf senescence index and other indicators were measured, and compared with natural light culture materials, so as to carry out lawn quality, indoor application of grass blankets and grass seed classification of grass blankets. The results showed that under indoor window culture and dark culture conditions, creeping bentgrass showed a trend of virtual length, with longer leaves, shorter roots and fewer tillers. Leaves pale, yellow and aging; Biomass reduction, etc. The dwarf lines 16 13-02, 16 13-4, 16 13-5 and 3603 cultivated in the window were compared with the creeping bentgrass variety Xuan Yue/kloc. Dwarf lines 16 13-02, 16 13-4, 16 13-5, 3603 were compared with creeping bentgrass variety Xuan Yue/kloc. The dwarf creeping bentgrass strain 16 13-02 has the advantages of slow indoor growth, strong plant vitality, high lawn and carpet quality, and shows the best indoor carpet application potential.
Key words: shade tolerance of grass blanket of creeping bentgrass dwarf strain
Evaluation of shade tolerance of bentgrass stolonifera dwarf lines: Xuan Yue 1 and bentgrass stolonifera new dwarf lines 16 13-0 1, 1 6/kloc. The results of 3-02 and 65438 showed that under indoor window cultivation and indoor dark conditions, creeping bentgrass showed an overgrowth trend, with the length of leaves increased, the length of roots shortened, the number of tillers decreased, the leaves turned pale and yellow, the leaves aged and the biomass decreased. Compared with Xuan Yue 1, the dwarf strains of bentgrass planted by indoor windows 16 13-02, 16 13-4,1610. Compared with Xuan Yue 1, the dwarfing lines of bentgrass 16 13-4, 16 13-5, 3603 and 3605-2 have higher plant height and biological characteristics. The dwarf line 16 13-02 of creeping bentgrass grows slowly and has strong viability when cultivated indoors. It has also become a kind of high-quality grass carpet, showing the best potential of indoor application of grass carpet.
