Hoagland nutrient solution promotes the growth of cucumber seedlings under light-emitting diode light

Abstract

Light-emitting diode (LED), as an efficient, energy-saving light source, has been widely used in artificial light plant production systems. It is confirmed that the combination of red and blue LED lights shows good performance on plant growth and development. Based on the hydroponic culture system in plant production factory, selection of a suitable nutrient solution for specific crop would be very important. In this study, four different widely used nutrient solutions (Hoagland, Garden-style, Yamasaki, and SCAU) were tested in perlite culture cucumber seedlings during 40-day growth under 2:1 ratio of LED lights with 12 h photoperiod at 100 ± 5 μmol m −2 s −1 irradiance. The plant growth, morphology, pigments, biomass, photosynthetic characteristics, and nitrogen (N), phosphorus (P), and potassium (K) content were measured. Cucumber seedlings treated with formula SCAU showed weak appearance, less biomass, and reduced photosynthetic activity compared with those supplied with Hoagland. However, the differences between formulae Garden-style and Yamasaki were not obvious, but both of them showed significantly higher plant height, leaf area, total leaf number, and shoot N content compared to SCAU. It is concluded that formula Hoagland shows better performance regarding cucumber seedling growth under LED light.

“…The sterilized seeds were soaked in water at 30°C for 2 d and then germinated for 3 d at 28°C. Seedlings were grown in Hoagland's culture solution as described previously (Li and Cheng, 2015 ). Plants were cultured in a growth chamber at 28°C under a 14 h light/10 h dark photoperiod.…”

Interaction of light quality and fertility on biomass, shoot pigmentation and xanthophyll cycle flux in Chinese kale

“…The nutrient solution developed by Hoagland and Arnon was recently compared with other nutrient solutions for cucumber under LED lighting . The Hoagland's nutreint solution produced greater biomass, higher Chl pigment concentrations and higher shoot tissue %N, %P and %K in cucumber.…”

“…The nutrient solution developed by Hoagland and Arnon was recently compared with other nutrient solutions for cucumber under LED lighting. 24,36 The Hoagland's nutreint solution produced greater biomass, higher Chl pigment concentrations and higher shoot tissue %N, %P and %K in cucumber. Shoot tissue FM, shoot tissue DM and Chl pigments for kale in the present study were significantly greater under half-strength fertility levels (Tables 1 and 2).…”
