Plant Growth and Photosynthesis Response to Low Potassium Conditions in Three Lettuce (<i>Lactuca sativa</i>) Types

Abstract: Chronic kidney disease has become a major public health problem worldwide. The aim of this study was to investigate the differences in plant growth and photosynthesis among three lettuce (Lactuca sativa) types with different morphological characteristics under low potassium conditions, providing information for improving the method of low-potassium lettuce culture. Lettuce was hydroponically grown in half-strength Enshi formula nutrient solution containing 4, 2, or 1 me·L In green leaf lettuce, reductions in b… Show more

“…Hypocotyl length, stem diameter, leaf area, and dry matter are the important factors in seedling quality [11,27,28]. The hypocotyl morphology of the cucumber scion affected the survival rate and growth after grafting [29].…”

“…The hypocotyl morphology of the cucumber scion affected the survival rate and growth after grafting [29]. Growth analysis including compactness, LAI, and LAR are used to understand the inherent differences in the response in plants under environmental stress conditions and can be used as important parameters to determine seedling quality [11,27,28]. A seedling with high plant compactness (i.e., high dry weight and short plant height) is considered as a high quality seedling [30,31].…”

“…The measured results are comparable with Fazilah et al [92], who found observed canopy cover of 33% and biomass yields of 0.22 ton ha −1 for lettuce under similar tropical conditions. Zhang et al [93] found higher measured biomass for lettuce with a range of 0.33 to 0.63 ton ha −1 under lower temperatures of 20-25 • C. Thus, high day temperatures above 23 • C often limit lettuce production [94]. Optimum growth for lettuce occurs between 15-20 • C [12].…”

“…In relation to the production of Brassica oleracea seedlings, Zhang et al [43] have demonstrated that although it depends on a relationship with other nutrients, the enrichment of substrate with K provides more vigorous seedlings. However, there is little research to verify if investment in seedling production is offset by the final productivity of plant in the field.…”
