The effects of shade levels and additional calcium nitrate on the morphology of Cyrtandrabracheia B.L. Burt / Siti Maslizah Abdul Rahman …[et al.]

The effects of different shade levels and additional calcium nitrate [Ca(NO3)2] were tested for morphology of Cyrtandrabracheia. Mature C bracheia plants were collected and the healthy leaves (2nd-3rd leaf from top) were chosen for propagation. After five months (3-4 leaf stage), homogenous new pl...

Mature C bracheia plants were collected and the healthy leaves (2nd-3rd leaf from top) were chosen for propagation. After five months (3-4 leaf stage), homogenous new plants were selected as plantlets and grown into 1.5 L pots with peat moss: perlite (50:50) and irrigation was provided three times per day.

In addition, 86% shade with additional [Ca(NO3)2]. had increased the leaf SPAD value. Higher leaf SPAD value comes with darker leaves, which is a preferred trait for foliage plants.
