Effect of LED lights on the in vitro growth of Pinus pseudostrobus Lindl., plants

Pinus pseudostrobus Lindl. is a species endemic to Mexico and widely used in reforestation programmes, as it highly adapted poor, shallow, limestone soils has high commercial importance. However, necessary preserve this genetic material since trouble due rates of deforestation, land use change, forest fires, so have effective strategies obtain good quality seedlings. Due the properties LED (light emitting diode) lamps for illumination production vitro plants, effects two different lighting systems (LED fluorescent) on an culture were analysed morphological characteristics growth photosynthetic pigment content P. The length root size seedlings affected by type illumination, where red light was most at 30 days evaluation. blue equally 60 seedling development. On other hand, fluorescent better terms number needles first stage, but we found be second stage. For content, highest values with light. results showed that system favours growth, development, under study.
