Abstract
|
|
|
We investigated the effects of various qualities of light-emitting diode (LED) light sources on the growth and carbohydrate accumulation of grape rootstock ¡®Teleki 5BB¡¯ culturedin vitro. Shoot fresh and dry weights and net photosynthetic rates were increased when plants were exposed to fluorescent lighting (control), red light, or a mixture of blue plus red, but were unaffected by blueonly radiation. Shoot elongation was significantly stimulated by red light whereas the combination of blue and red light was associated with the shortest shoots. However, the number of nodes did not differ among these treatments. Under monochromic blue or red light, sugar content and starch accumulation increased under the mixed-radiation treatment.
