Abstract

Effects of red and blue LEDs on in vitro growth and microtuberization of potato single-node cuttings

Highlights

Potato (Solanum tuberosum L.) is the third most important food crop after rice and wheat in the world in terms of human consumption according to International Potato Center[1]
Where MTTC indicates the reduction value of TTC, FW indicates the fresh weight of root and T indicates the reaction time
Potato plantlets grown in vitro and radish plants grown under pure red light have sufficient IAA to sustain stem elongation growth, while the opposite was found for those grown under pure blue light[6,31]

Summary

Introduction

Potato (Solanum tuberosum L.) is the third most important food crop after rice and wheat in the world in terms of human consumption according to International Potato Center[1]. This crop is vulnerable to virus infection when field propagated using potato tubers from. Light is a crucial environmental factor that influences the in vitro growth and development of potato plantlets[3], because they are strongly affected by the light spectrum[4]. It was reported that potato plantlets grown in vitro under red light were weak and slim with small leaves while those under blue light were short and sturdy with well-developed leaves[6]. The addition of green LEDs to the combination of red and blue LEDs lights promoted potato plantlet growth[10]
