Abstract

Nepenthes gymnamphora is an endemic pitcher plant species in Java Island and one of the plant collections of Baturraden Botanical Garden. N. gymnamphora is a dioecious plant and its sex cannot be differed in vegetative development. Conservation efforts can be carried out more efficiently when sex identification is performed earlier thus leading to effective development of particular sexes. Random Amplified Polymorphic DNA (RAPD) technique is one molecular approach that can be employed in early identification of N. gymnamphora sex. The aims of this study are to assess whether there is difference of RAPD patterns between male and female N. gymnamphora and to find out how the difference is. Explorative method was applied to this study involving five N. gymnamphora individuals of Baturaden Botanical Garden collection of different sexes as samples. Genomic DNAs were extracted from youngest leaves of the five samples (two males, two females and one individual of unknown sex) and then used as templates to amplify RAPD markers. Five random primers were used in the amplification, i.e. OPK-16, OPP-15, OPA-15, OPP-08, and OPD-20. Two primers, i.e. OPP-08 (5’-ACATCGCCA-3’) and OPD-20 (5’-ACTTCGGCCAC-3’), produced RAPD bands of approximately 300 bp in males and sexually unknown individual. These bands did not appear in females, so that it can be presumably related to sex determination genes in N. gymnamphora. Primer OPP-08 also produced RAPD bands of approximately 250 bp in females individual. These bands did not appear in males, so it can be presumably related to sex determination genes in N. gymnamphora.

Abstract

Nepenthes sp. has a characteristic in the form of a modified leaf tip into a pitcher. Nepenthes mirabilis (Lour.) Druce in its original habitat is widely hunted for sale. Propagation of N. mirabilis in nature has very little success rate, to overcome this it is necessary to propagate it by means of in vitro culture and use young leaf explants to form callus. Growth regulators such as Auxins (NAA) and Cytokinins (TDZ) can stimulate callus growth. Auxins can stimulate callus formation by stimulating cell expansion and cytokinins can stimulate the cell division process. The purpose of this study was to determine the effect of NAA and TDZ in inducing N. mirabilis callus and to determine the interaction between NAA and TDZ in inducing N. mirabilis callus. The experimental design used was a factorial CRD pattern, with two factors, namely NAA and TDZ. NAA consists of four levels, namely, 0 mg / L (N0); 0.5 mg / L (N1), 1 mg / L (N2) and 1.5 mg / L (N3). TDZ also consists of four levels, namely 0 mg / L (T0); 1 mg / L (T1); 2 mg / L (T2) and 3 mg / L (T3). Each treatment was repeated three times. The results showed that the addition of NAA and TDZ had an effect on callus induction of N. mirabilis. The TDZ concentration of 1 mg / L (T1) stimulated callus induction, especially the percentage of callus formation and callus diameter. Meanwhile, NAA 1 mg / L (N2) boosted the percentage of N. mirabilis callus formation.

Abstract

Nepenthes adrianii is an endemic species of Mount Slamet. The existence of this species has begun to be threatened. This situation encourages efforts to conserve N. adrianii, which is through propagation using stem cuttings of N. adrianii. In order for the propagation of stem cuttings to grow properly, it is necessary to add growth hormone (ZPT) from the auxin group such as NAA (Napthalene Acetic Acid). This research has been conducted to study the effect of NAA and its effective consentration for the growth of N. adrianiistem cuttings. This research was conducted using experimental methods. The experimental design used was a Randomized Completely Block Design (RCBD). The block in this study is total leaves per cuttings. Block 1 is the leafless cuttings, block 2 is cuttings with one leaf, block 3 is cuttings with two leaves, and block 4 is cuttings with three leaves. The NAA concentrations in this study are 0, 5, 10, 15, 20, and 25 ppm. There are a total of 24 experimental units. The variable observed was the growth of N. adrianii stem cuttings. Parameters observed in this study are days taken for sprouting, number of shoots, number of leaves, leaf length, and leaf width. The results were analyzed using Variety Analysis and then analyzed with Tukey's test at the test level of 0.05 at the time of significant treatment. The results showed that the application of NAA did not affect the growth of the stem cuttings of N. adrianii. The best concentration of NAA could not be determined because there was no effect of NAA on the growth of N. adrianii stem cuttings.
