“…The generalized pollen morphology of all the species in the genus Globba are monad, radial symmetry, apolar, and inaperturate, which is similar to that of most genera in Zingiberaceae [9][10][11][12][13][14][15]20 . The medium sized pollen grains are the most dominant and are found in 18 taxa of Globba in this study.…”

“…The pollen morphology of Zingiberaceae has been studied by various researchers. They have used many characteristics of the pollen grains for identifying the species of plants, i.e., shape, size, symmetry, and polar aperture [9][10][11][12][13][14][15] , and for classification at the generic and sectional levels 16 . The pollen morphology of the genus Globba has been studied by various researchers [17][18][19] .…”

Pollen morphology was investigated in 22 taxa of the genus Globba (Zingiberaceae) from Thailand by means of light microscopy and scanning electron microscopy. The pollen grains of all taxa examined are monad, radially symmetric, apolar, and inaperturate. The sizes of the pollen grains are medium and large. The pollen grains have various shapes: oblate-spheroidal, spheroidal, and prolate-spheroidal. The exine ornamentation is short-echinate with psilate between the spine, short-echinate with rugulate between the spine, and psilate. The two types of spine apex are blunt and sharp. Palynological data has not been useful at the specific level. The leaf anatomy of 26 taxa was investigated by epidermal peeling and transverse sections of the leaves. The results indicate that the significant leaf anatomical characteristics for species identification are types of stomata, types of trichome, number of rows in intercostal regions, position of hypodermis, shape of midrib, types of vascular system, shape of midrib and leaf margins in transverse sections, and cell inclusion. Based on these anatomical characteristics, an identification key for Globba at the species level is given for the first time.

“…Pollen color was visually classified based on hydrated pollen which were examined under light microscope (LM). Samples were not acetolyzed based on the reports of Liang (1988) and Saensouk et al (2009) that members of the Zingiberaceae are mostly not resistant to acetolysis due to their very thin exine and thick intine wall. For the other pollen morphological features such as shape, aperture and ornamentation, they were classified following the criteria of Liang (1988), Liang (1990), Theilade et al (1993), Saensouk et al (2009), and Chen & Xia (2011).…”

The pollen viability and pollen tube growth of Etlingera dalican and Etlingera philippinensis (Zingiberaceae) were examined from fresh samples under the light microscope (LM) and scanning electron microscope (SEM). Pollen measurements were 68-75μm (E. dalican) and 60-65μm (E. philippinensis), having spheroidal shape for hydrated pollen and irregularly-shape for dry pollen for both species. E. dalican pollen has greenish-yellow color while that of E. philippinensis is greenish. Both species had inaperturate pollen but differ in their ornamentation which is gemmate in E. dalican while psilate in E. philippinensis. E. dalican has 88.56% pollen viability while E. philippinensis has only 40.69%. The rate of pollen tube growth was faster (17.75 μm per day) in E. dalican than E. philippinensis (8.17 μm per day). The possible pollinators observed for the two species were butterflies of the genus Catopsilia, ants and flies. Additional information on the inflorescence and flower description of the two species are herein presented.

“…Besarnya nilai proporsi keragaman menunjukan rendahnya tingkat keragaman antar aksesi yang diamati (Suketi et al, 2012). Hal ini diduga karena tanaman genus Curcuma tidak dapat membentuk biji/steril (Saensouk et al, 2015), dengan demikian perbanyakan tanaman seperti ini dilakukan secara vegetatif menggunakan rimpang. Tanaman yang membiak secara vegetatif memiliki tingkat keragaman yang rendah.…”

Curcuma aeruginosa Roxb. or black turmeric belongs to the family Zingiberaceae is one of the important medicinal plant that is widely distributed in Southeast Asia, including in Indonesia. This plant has been used by the people especially as raw material for medicine and cosmetics industries. However, the development of black turmeric is still constrained by the availability of germplasm collection and improved varieties. The objective of this study was to determine the vegetative morphological characters and phylogenetic relationship among 10 accessions of black turmeric and 3 accessions of genus Curcuma in Indonesia. Data was collected for 15 morphological quantitative characters of black turmeric at the Experimental Garden at Sukamantri IPB based on UPOV and PPVFRA descriptors. The result of principal component analysis has determined three principal components with the proportion of diversity 73.94%. Cluster analysis three clusters accession of black turmeric, namely cluster 1 consisted of accession Cianjur, Malang, Rimbo, and Kendal; cluster 2 consisted of accession Bogor, turmeric (Curcuma longa L.), java turmeric (Curcuma xanthorrhiza Roxb.), Liwa, Natar, white turmeric (Curcuma zedoaria Roscoe.); cluster 3 consisted of accession Cirebon, Kuningan 1, and Kuningan 2.
