“…The high genetic similarities among the spesies show the presence of some associations in the evolutionary processes in Dacrycarpus and Podocarpus (Figure 3). The relationship between Dacrycarpus and Podocarpus has evaluated by the low rates of nucleotide substitution within sequences, suggesting that trnL (UAA) intron suitable for phylogenetic studies [14].…”

The conservation of Jamuju Dacrycarpus imbricatus in Java Island has been considered important. One of the the limitation of such program is related to the viability data on the genetic diversity of species target. The aim of study was to determine genetic variation of D. imbricatus in Bromo Tengger Semeru National Park (BTS-NP), East Java based on trnL (UAA) intron region. DNA sample was collected from several D. imbricatus seedling population in BTS-NP in East Java. DNA was isolated and amplified using PCR. Genetic variation was estimated using trnL (UAA) intron sequences. This study confirm that D. imbricatus in BTN-SP has low genetic diversity. Based on the phylogenetic tree, D. imbricatus population from BTN-SP is closely related to D. imbricatus from Sabah-Malaysia and HainanChina with 100 % similarity value. These data implies that population and habitat management of D. imbricatus in BTN-SP should be designed to enhance the population survival in the future.

“…Dodder species are very difficult to visually differentiate, and some taxonomy is controversial (Stefanovic et al 2007). Recent and ongoing genetic work with dodder populations on Massachusetts cranberry bogs suggests that multiple species are present (Kim et al 2004;K. Ghantous, unpublished data).…”

Dodder seeds are physically dormant because of hard seed coats and do not readily germinate without scarification. Reliable methods of scarification for small lots of dodder seed are needed to facilitate laboratory, greenhouse, and field research projects. Dodder seed was scarified for varying times using a handheld rotary tool at the 10,000 rpm setting with a conical grinding-stone bit attached. Percentage of germination and weight change of seeds were assessed using scarification times between 0 and 4 min at 0.5-min increments. Mean seed weight loss and mean number of germinated seeds increased quadratically as scarification time increased. Scarifying for 2.5 min was judged the shortest time with maximal germination. Another study evaluated the effect of seed number (100 to 400 seeds sample−1) on the efficacy of rotary tool scarification when scarification time was held constant at 2.5 min. Percentage of germination decreased linearly as seed batch size increased. The handheld rotary tool provides consistent and repeatable scarification of dodder seed with germination rates greater than 80%.
