Effect of population sources and clones to growth variation of Shorea leprosula Miq shoot cuttings

Abstract

Vegetative propagation has an important role in production of high quality planting stocks. Through vegetative propagation, the genetic potential of a mother tree will totally be inherited to the off-springs.This study aimed to determine the effects of population sources and clones on growth variation of Shorea leprosula Miq shoot cuttings. Randomized Complete Block Design (RCBD) was used as an experimental design; which consists of two factors, i.e population sources (Muara Wahau, Berau, Kenangan, Ketapang and Carita) and clones (40 clones). In this study clone was nested in the population. The results showed that the clones and population sources influenced the rooting percentage, height growth, number of root, length of root and number of leaves of S. leprosula shoot cuttings. Rooting percentage of clones ranged between 66.7 – 100.0% (2 groups difference), height growth ranged between 2.60 – 6.80 cm (6 groups difference), number of root ranged between 2.1 – 5.7 (9 groups difference), length of root ranged between 4.3 – 15.8 cm (8 groups difference) and number of leaves ranged between 1.17 – 3.57 (5 groups difference).

Leaf morphological traits of nine major tropical trees of Shorea species (Dipterocarpaceae)

“…S. leprosula is widely spread and generalist species (Ng et al 2020). However, when compared to other Dipterocarp species, S. leprosula is categorized as a fast-growing Shorea species (Mashudi 2017;Ngatiman and Fajri 2018). S. leprosula is one of the priority target species to be mass planted in the national program called Intensive Silviculture System (SILIN) with diameter growth ranging from 1.15 to 2.20 cm/year on various experimental sites (Naiem et al 2014;Pamoengkas and Prasetia 2014).…”
