Study on seed anatomy of Sungkai (Peronema canescens Jack); a viability perspective

Abstract

Sungkai (Peronema canescens Jack) is a member of Verbenaceae family. It has been registered on the National Industrial Timber Estate Programme. Its large-scale propagation was usuallly carried out by vegetative or stem cuttings, therefore it had significant limitation. Due to the low germination rate, so the generative propagation was not yet a prime target. Fruits as well as flower biology remain open so intensive study. Beside the case of low germination rate, the purity test on the whole fruits resulted in an assumption on three categories, i.e. (i) low percentage of fruits containing full seeded segment, (ii) fruits posses a splitting mechanism into separate half-seeded fruit, (iii) morphologically difficult to recognize a full-seeded fruit.

Annual Tree-Ring Curve-Fitting for Graphing the Growth Curve and Determining the Increment and Cutting Cycle Period of Sungkai (Peronema canescens)

“…People living in villages also commonly plant Sungkai for shade trees, live fences, and decorative plants in gardens, backyards, and urban forests. Although its growth is slightly slower than other fast-growing species (i.e., Acacia mangium, Albizia falcataria, and Eucalyptus grandis), Sungkai offers several significant benefits [7] such as (1) vegetative propagation by stem cutting [8] can complement its generative seedling regeneration [9]; therefore, it does not depend on the flowering and fruiting season; (2) its tenacity enables planting in a wide range of environmental condition; (3) most parts of the tree (leaves, bark, root, and wood) are traditionally useful for medicine, pharmacology, and as phytoconstituents [10][11][12]; and (4) its timber is high quality and luxurious.…”
