Abstract
The study was conducted in pots to determine the effect of different shade levels (open field condition, 35%, 50%, 75% and 90%) on growth and development of Peace lily (Spathiphyllum cochlearispathum (Liebm.) Engl.) during 2018-19 under the subtropical region of Ludhiana, India. The optimum shade level on vegetative growth and quality production was evaluated at quarterly intervals for plant growth. Shade nets not only secure plants from high light intensities but also increase the vegetative growth, quality and vase life of cut foliage of Spathiphyllum. Plants which were grown under open field conditions were severely affected during both the extremes. Plants grown under 75% shade level showed best vegetative parameters such as plant spread, leaf length, No. of leaves per plant, leaf thickness, petiole girth, fresh and dry weight of leaves and flower parameters such as No. of flowers per plant, flower stalk diameter when compared to other treatments. Plant height, leaf breadth, chlorophyll content of leaves, flower stalk length, spathe length, spathe breadth and vase life was increased with increase in shade levels and seen highest under 90% shade level but these were at par with 75% shade level. So it can be concluded that Spathiphyllum plants don‘t survive under open field conditions and require 75% shade for their optimum growth and development.
