Qothrunnada Sungkar, Tatik Chikmawati & Nina Ratna Djuita. 2017. Leaf Anatomy of Rambutan (Nephelium lappaceum L.) and Its Relatives. Floribunda 5(6): 192–199. — Rambutan belongs to the Sapindaceae family that has closely related to longan and lychee. The observation on leaf anatomy of rambutan, longan, and lychee was conducted to provide information about leaf anatomy of Sapindaceae’s members. The anatomical features of leaf paradermal and transversal sections were examinated on four varieties of rambutan namely binjai, rapiah, sikoneng, and aceh lengkeng; and two closely related families, longan and lychee. All rambutan cultivars and lychee had the same stomata type: cyclocytic, while stomata in longan was surrounded by six subsidiary cells. Epidermal cells of rambutan and lychee leaves have polygonal shape with flat side, whereas epidermal cell of longan has polygonal shapes with notched. Based on transversal sections, rambutan, longan, and lychee have bifacial type, but they are differed in the number of palisade layer and the shape of palisade cellls. Leaf anatomical characters could be used to distinguish between rambutan and its closed relatives, longan and lychee; but it could not be used to differentiate among rambutan’s cultivars.Keywords: longan, lychee, rambutan, Sapindaceae, stomata type.Qothrunnada Sungkar, Tatik Chikmawati & Nina Ratna Djuita. 2017. Anatomi Daun Rambutan (Nephelium lappaceum L.) dan Kerabatnya. Floribunda 5(6): 192–199. — Rambutan merupakan tumbuhan yang termasuk ke dalam suku Sapindaceae dan masih berkerabat dekat dengan lengkeng dan leci. Pengamatan tentang anatomi daun Sapindaceae masih jarang dilakukan, sehingga penelitian ini perlu dilakukan untuk memberikan informasi mengenai anatomi daun beberapa anggota Sapindaceae. Pengamatan ciri anatomi dari sayatan paradermal dan transversal dilakukan terhadap empat kultivar rambutan yaitu rambutan binjai, rapiah, sikoneng, dan aceh lengkeng, serta dua kerabat dekatnya yaitu lengkeng dan leci. Hasil sayatan paradermal memperlihatkan bahwa stomata tidak ditemukan di permukaan atas daun rambutan, lengkeng, dan leci. Stomata pada daun rambutan dan leci adalah stomata dengan tipe siklositik, sedangkan stomata pada lengkeng dikelilingi oleh enam sel tetangga. Epidermis pada daun rambutan dan leci berbentuk poligonal dengan sisi rata, sedangkan sel epidermis pada daun lengkeng berbentuk poligonal dengan sisi berlekuk. Sayatan transversal memperlihatkan bahwa daun rambutan, lengkeng, dan leci bertipe bifasial. Ketiga jenis berbeda pada jumlah lapisan palisade dan bentuk sel palisade. Ciri anatomi daun dapat digunakan untuk membedakan rambutan dari kerabat dekatnya, leci dan lengkeng; tetapi tidak dapat digunakan untuk membedakan antara kultivar rambutan.Kata kunci: lengkeng, leci, rambutan, Sapindaceae, tipe stomata.

Nina Ratna Djuita, Alex Hartana, Tatik Chikmawati, Dorly. 2020. Genetic Diversity of Pulasan [Nephelium ramboutan-ake (Labill.) Leenh.] of Java Based on SSR and ISSR Markers. Floribunda 6(4): 117–126. — Pulasan is one of the potential local fruits to be developed. This study aimed to analyze the genetic diversity of pulasan of Java using Simple Sequence Repeat (SSR) and Inter Simple Sequence Repeat (ISSR) markers and to obtain information whether primers of the markers could be used to distinguish male and her-maphrodite plants. The results showed that two primers in the SSR markers and seven primers in the ISSR markers produced polymorphic bands. The genomic DNA of the pulasan amplified with SSR markers produced bands 140–500 bp, while those from the ISSR markers were 150–1500 bp. The population of pulasan in Babakan Madang has the highest genetic diversity, while that of Patean is the lowest. Genetic variation of pulasan based on SSR and ISSR markers in the population and among populations have different compositions. Variation in the population is 72% while among the population is 28%. Primers of LML Y6 and LML Y12 from SSR markers and primers of ISSR 2, 3, 4, 5, 6, 8, 9 cannot be used to distinguish male and hermaphrodite pulasan plants.

Recent more intensive explorations and collections of hornworts in Mt. Slamet indicated that six species can be recognized, namely Anthoceros punctatus, Folioceros fuciformis, Phaeoceros carolinianus, P. exiguus, Dendroceros difficilis, and Megaceros flagellaris. Since originally only one species D. difficilis was recorded from this area, this means that five species represent new records for the area, whereas P. exiguus is not only a new record for Java, but it is also a new record for Malesia.

Pulasan is an androdioecious plant that has both male and hermaphrodite flowers on separate plants. The objectives of this study were to obtain data about the anatomical structure of pulasan flower and to investigate whether the pistil and the stamens of pulasan flower reach maturity at different times. The anatomical observation was done on compound flowers taken from three male trees and three hermaphrodite trees. Two compound flowers that still in buds, about to bloom and fully bloom were picked from each tree. Flowers were observed in a cross and longitudinal section. The results showed that the sepals of pulasan flower comprised of the uniseriate epidermis and multilayered polyhedral parenchymal cells. Stamen development started from the anther followed by the formation of the filament. The pollen of hermaphrodite pulasan flowers reached maturation earlier than the pistil. The pistil development started from the expansion of meristem cells in the center of the flower and ends with the warp of the stigma.

Ibna Hayati, Alex Hartana, Nina Ratna Djuita & Nunik Sri Ariyanti. 2022. Morphological Variation of Kedondong (Spondias dulcis Parkinson) in Central Part of Sumatra. Floribunda 6(8): 315–323 — Kedondong (Spondias dulcis Parkinson), is widely cultivated in the tropics and reported possibly native plant from Malesia and Pacific. Since a long time several regions in Indonesia has been known as producing area. Around 60s, Sumatra has reputable kedondong from sabang which has sweet flavour and large size. However information on the morphological variation of kedondong germplasm is still limited. The objective of this study was to describe and grouped morphological variation of kedondong germplasm in central part of Sumatra. The specimens were explored and collected from Riau, West Sumatra, and Jambi. Fifty morphological characters were observed and scored for grouping analysis using UPGMA methods. Some characteristics of kedondong from central part of Sumatra are very varied. The kedondong specimens in the cluster analysis grouped into two main groups A and B based on the color of the mature fruit, but these characteristics may not qualify to be used as standard criteria for evaluating cultivated variety because within the group there are still variations in other characters, such as size and shape of the fruits. However based on fruit type, sweet kedondong tends to has oblong type.

The red list of the International Union for the Conservation of Nature and Natural Resources (IUCN) reported Castanopsis argentea as an endangered species. Studies about autecology on its natural habitat become important to perform species conservation. This study aimed to analyze the population structure, distribution pattern, and environmental factors that influence the presence of C. argentea in the Telaga Warna Nature Reserve. Data was collected in September 2020 by making 21 plots with a single plot. The purposive sampling method was used based on C. argentea representatives to determine plot location. Measurement of environmental factors, including soil sampling was carried out on each plot. Population structure was analyzed based on plant density, and Morisita index determined the distribution pattern. Environmental data were analyzed using PCA with Minitab 19 programs. Our field observation showed that C. argentea seedling has the highest density (1071 ind/ha) and decreased in the mature phase. C. argentea was found to have a clumped distribution pattern with an Id value of 1.03. PCA analysis showed differences in environmental factors that were thought to influence the presence of C. argentea individuals in four growth phases. The highest population structure of C. argentea was found in the growth phase of seedlings and saplings at an altitude of 1400 m asl. The spread population distribution of C. argentea was clumped. The influences of environmental variables on the existence of C. argentea were Mg, Ca, CEC, pH, and soil moisture.

Pulasan (Nephelium ramboutan-ake (Labill.) Leenh) fruit is highly similar to rambutan rapiah (Nephelium lappaceum) fruit with ovate shape, sweet and sour fresh taste, but it has a thick rind. The diversity of pulasan is little informed including in Bogor. The objective of this study was to analyze the genetic diversity of pulasan from Bogor revealed by microsatellite marker. The DNA of 63 individuals from 10 populations of pulasan were extracted using CTAB method and amplified using two primer sets, LMLY6 (GA)9(CA)2(GA)4 dan LMLY12 (CT)11. DNA amplification product was visualized and arranged in a matrix of binary data then analyzed the value of the number of different alleles (Na), the number of effective alleles (Ne), Shannon information index (I), heterozygosity (He), and the percentage of polymorphism (PLP). The results of the analysis showed the highest genetic diversity was found in North Bogor (He=0.313). The genetic diversity within a population (61%) was higher than that among populations (39%). A dendrogram was constructed using the Unweighted Pair Group Method with arithmetic Mean (UPGMA). The similarity index ranged from 52 to 100% that means there are close relationships among individuals. Cluster analyses grouped some individuals originated from different locations in the same group. The levels of heterozygosity within a population was determined by the history of each individual in a population.
