Abstract:
Taking dwarf-type zucchini (Cucurbita pepo L.) seedlings as the test materials and artificial lighting as the research method,six different light quality combinations were set up in an artificial climate incubator for light treatment,the effects of seedling photosynthesis and growth characteristics of different light quality combinations on zucchini were studied,in order to obtain the best combination of light quality for growing zucchini seedlings and improve the quality of seedlings.The results showed that,under the light quality combination of 140 μmol?m-2?s-1 for red light,112 μmol?m-2?s-1 for blue light,and 28 μmol?m-2?s-1 for yellow light,the net photosynthetic rate,chlorophyll content,and strong seedling index of the seedlings were significantly higher than those of the control.The seedlings had dark green leaves,thick stems,and dwarf plants.They also had obvious advantages in raising seedlings.
