Studies on the shade-tolerant or shade-loving ground cover plants

Abstract

Landscape architects grow different types of plants usually in the shade of trees or in the northern side of buildings in order to create shady sourroundings.There are many terminologies such as “Heliophytes. Helio-Sciophytes, Sciophytes”; “Light plants, Shade plants, Shade-tolerant plants” etc., which signiby different types of plants grown in varied ecological light intensity. These plants, especilly plants for landscaping have not been studied in detail.In this experiment a search has been made to Find out shade-tolerant or shade-loving plants.Twelve species of ground cover plants (Table 5) were grown in a desingned experimental plot (Fig. 1).From the present expermental data (Table 6, Fig 2), twelve species of ground cover plants have been classified into four groups as follows:I High-grade-sun-loving plants, designated as “High-grade-sun-loving plants”. These plants cannot grow at all in the slight shade.For example, Tifton 328 Bermuda grass, Manila grass (HIMEKORAISHBA), st. Augastingrass.II Sun-loving plants, designated as “Sun-loving and slight-shade-tolerant plants”. These plants can grow in the slight shade.For example, Kentucky 31 fescue, Orchard grass.III Slight-shade-loving plants, designated as “Slightshade-loving plants”. These plants cannot grow in the dense shade.For example, Dichondra repens (AOIGOKE), Dichondra micranta (Dichondra), Ranunclus repens (HAIKIMPOGE), Sedum Makinoi (MARUBAMANNENGUSA), Sedum lineare (ONOMANNENGUSA).IV Slight-shade-loving plants, designated as “Slightshade-loving and danse-shade-tolerants plants”. these plants can grow in the dense shade.For example, Japanese spurge (FUKKISO), Reinekia carnea (KICHIJOSO).
