Some Physiological Studies on Ornamental Ipomora Batatas as a Groundcover Species
The morphological development and some physiological aspects were studied on two cultivars of sweet potato which are normally used as an ornamental plant. Among the studies under taken were those on the botanical characteristics of the plants, effects of shade and fertilizer and nutrient uptake....

| description |
The morphological development and some physiological aspects were
studied on two cultivars of sweet potato which are normally used as an
ornamental plant. Among the studies under taken were those on the
botanical characteristics of the plants, effects of shade and
fertilizer and nutrient uptake. The cultivar examined were Imelda and
an unnamed 'variegated' type.
The effects of shading and fertilizer levels showed growth of the
'variegated' cultivar were severely reduced in heavy shading (70% and
80%). Increasing shade levels increased leaf area ratio (LAR) and
leaf area to leaf weight (LALW), but decreased dry matter production,
visible quality, chlorophyll content and elemental composition in the
leaf tissue. However, fertilizer levels were less effective than shade
in altering the parameters above. As shade level sincreased, the
content of nitrogen, phosphorus, potassium, calcium and magnesium in the leaves increased. |
