A comparative study of the research on the different light quality color bell pepper (purple elegant red Indah and yellow Opel ) seedling quality , developmental characteristics and photosynthetic characteristics . The results show that : 1 under different light quality , white and yellow cultivate strong sprout effect is better, other light quality followed by blue, red and green . Green light plant height than white 26.2% and 28.6% , respectively , and blue , respectively 14.7% and 14.3% lower than the white , green and red stem elongation significant role in promoting the Blu-ray on seedling dwarf role ; stem diameter smaller white light , yellow and blue , followed by green and red light . Compare different treatments of dry matter , white favor dry matter formation , followed by yellow and red dry matter accumulation , a very significant difference between green and blue light under the minimum varieties , the composite light than monochromatic effect better . As can be seen from the seedling index seedlings robust high under the white and yellow , blue and red under quite green seedlings significantly leggy . No significant differences between the varieties . Blue and white under the free amino acids in the highest , and green and yellow , followed by red lowest . The higher the content of free amino acids to provide a basis for a higher protein synthesis . Varieties between red Indah content highest , followed by yellow Opel purple elegant minimum. Green , three varieties of root activity equivalent were lower , the green light is not conducive to the development of plant roots , is not conducive to the absorption of plant nutrients ; yellow and white root activity , the plant grows stout , Blu-ray followed red light weakest . White light has the highest content of soluble proteins , Blu-ray Secondly , less red and yellow , the green light under the minimum , the green light under the total enzyme activity is very low, is not conducive to the growth of plants . Red Indah content between varieties higher , followed by yellow Opel , purple elegant minimum . 2 the same light quality the color the sweet pepper Chl.a content of different varieties and Chl.a / Chl.b differences significant ; under blue Chl.a Chl.b Chl total The existing of chlorophyll a / Chl.b values highest , white and yellow handle , followed by the low , red , green, minimum . Different light quality , Chl.b content than Chl.a stable, Blu-ray the synthesized Chl.a than Chl.b amount , purple elegant and red Indah blue Chl.a content
