ABSTRACTSomatic cell manipulation of Artemisia annua L. was conducted by induction of polyploid plants with Colchicine and Oryzalin in order to increase level of artemisinin. Polyploid plantlets were multiplied on MS medium without plant growth regulators. After acclimation processes, plants were grown in the field for agronomic performance observation. Survival rate of plantlets was recorded. Agronomic performance of plants was observed by recording height of plants, number of branches, leaf biomass, stomatal characteristics, and artemisinin content. The results showed that survival rate of the plantlets from Colchicine and Oryzalin treatments were ranging from 13.40 to 33.33% and 11.11 to 41.67%, respectively. Growth rates of plant height and plant branching were not significantly different between diploid and tetraploid plant both from Colchicine and Oryzalin treatments, except to triploid plants from Colchicine treatment. Averages of plant height from Colchicine and Oryzalin treatments were ranging from 10.0 to 220.0 cm and from 35.0 to 186.0 cm, respectively. The averages number of branches per plant of polyploid plants from Colchicine and Oryzalin treatments were ranging from 3 to 66 and from 11 to 63, respectively. Averages of dry leaves biomass between diploid and tetraploid plant from Colchicine and Oryzalin treatments were also not significantly different. They were ranging from 12 to 64 g/plant and from 11 to 62 g/plant, respectively. However, tetraploid clones have bigger size of stomata and produced more artemisinin than the diploids.Keywords: Artemisia annua L, Colchicine, Oryzalin, Polyploids, Acclimation, Agronomic performance

The experiment was conducted from June to October 2009, at Cibodas Botanical Garden. The design used in the experiment was completely randomized block with two treatments and three replicates. The first factor was four kinds of planting media (sand + husk (2:1), sand + compost (1:1), husk + compost (1:1), compost). The second factor was three kinds of fertilizers (growmore, gandasil D, hyponex) and one treatment without fertilizer (control). The results of experiment show no interaction in almost all parameters between planting media and compound fertilizers. Statistically, all parameters observed show significance (? = 0,05 and ? = 0,01) at various media. Based on the study, the best media were compost and sand + compost (1:1). These media were recommended for R. pyrifolius seedling growth.Keywords : Rubus pyrifolius, planting media, fertilizers

Artemisia annua L. is known as one of the plants producing artemisinin, i.e. active compound that is used for anti-malaria theraphy. This plant has potency to be cultivated in Indonesia through seedlings and cuttings. The objective ofÂ this study was to compare growth and biomass allocation of plants from seedlings and cuttings. The experiment was set usingÂ Completely Randomize Design with one factor. The factor is type of plant propagation which cutted plant derived from three different ages of mother plants (1.5, 2, and 2.5 months after planting) and seedlings as control. The result showed that growth and biomass alleviation of the cuttings plants are more rapid than the seedlings. However, the cutting plants were flowering earlier than the seedling. At three months after planted, more than 70% of the cutting plants population have flowered. It is implied that the plants from cutting will loss about 70% of its yield potency than the seedling. On the other hand, there was no significant effects of the ages of mother plants on growth and biomass of the cutted plant (p>0.05). Therefore, seedlings were more effective than cutted plant on A. annua cultivation.Â Keywords: artemisia annua L., biomass allocation, cuttings, growth, seedlings.Â

Most artemisinin is extracted from an annual herb Artemisia annua L. but the cultivation in Indonesia is limited bythe low yield of the artemisin incontent that is not economically beneficial to industry. Improvement on cultivatedvarieties and cultivation techniques is therefore needed. This work aims to improve the cultivation techniques byevaluating the application effects of NPK, manure, and VAM on the artemisinin yield of A. annua. The experimentwas set using a Split Split Plot Design involving three factors. First factor was the application of four dosages ofNPK (0 kg ha-1 as a control; 40:40:40 kg ha-1; 80:80:80 kg ha-1; and 120:120:120 kg ha-1). Second factor wasmanure addition (using 0 ton ha-1 and 150 tons ha-1). Third factor wasthe application of mycorrhiza (0 g plant-1and15 g plant-1). The experiment was divided into three different groups based on the seed sources (Bandung, Cibodas,and Tawangmangu plants) using similar treatments. The results showed that the plant growth (Relative GrowthRates/RGR of plant heights and number of branches), leaf yield, and total plant biomass were much affected byNPK. The addition of manure has less significant effect on those parameters. Only VAM seems to influence theartemisinin content. The highest artemisinin yield (5 kg ha-1) was relatively low when compared to the productionin USA, China, and Brazil. However the result shows that a low fertilizer input of 40:40:40 kg NPK ha-1 and aninoculation of VAM were recommended for cultivating A. annua resulting a significantly high yield of artemisinin.Keywords: Artemisia annua L., Artemisinin content, NPK, Manure, VAM, Plant Growth, Biomass

Syzygium is a genus of Myrtaceae with 1,236 species. The functional traits of each species vary. The purpose of this study was to determine the variation in the functional traits of Syzygium leaves found in the lowlands and highlands. In this study, Syzygium leaves were collected from the Bogor Botanical Garden (lowland) for 27 species, while from the Cibodas Botanical Garden (highland) for 35 species. Ten parameters were measured, including leaf Fresh Weight (FW), leaf Dry Weight (DW), Leaf Area s(LA), Specific Leaf Area (SLA), Leaf Dry Matter Content (LDMC), Specific Leaf Weight (SLW), Chlorophyll Content (CC), Stomatal Density (SD), Stomatal Length (SL), and Stomatal Width (SW). Based on the results of the study, a diversity of functional traits in Syzygium species was observed in the lowlands and highlands. The results also indicated that the elevation influences variations in functional traits. Most of the leaf traits were found to be higher in the lowland species. Phenotypic plasticity of parameters was observed within the species found in both lowland and highland locations

Rhododendron multicolor Miq. exhibits distinctive morphoanatomical characteristics and various bioactive compounds with medicinal and horticultural potential. Numerous studies indicated Rhododendron species are widely utilized as medicinal and ornamental plants, owing to their diverse phytochemical profiles and distinctive morphoanatomical characteristics. However, comprehensive studies of the morphoanatomy and leaves metabolite profile of R. multicolor are still limited globally, as well as its minimal utilization by local communities, highlighting a significant knowledge gap. Therefore, this study aimed to analyze the morphology, paradermal anatomy, and metabolite profile of young leaves and mature leaves of R. multicolor. Morphoanatomy characteristics were analyzed descriptively, anatomical features were analyzed using specific formulas, and metabolite profiling was analyzed using qualitative phytochemicals and gas chromatography-mass spectrometry (GC-MS). The result shows that R. multicolor is a shrubby plant characterized by funnel-shaped flowers in a vibrant red hue, along with narrowly elliptic, scaly leaves. The scales are stellate lobed irregularly with lower density than stomata; the epidermis is polygonal to irregular that has a higher density compared to stomata. The results of the qualitative phytochemical test of Rhododendron multicolor are that it contains phenols, flavonoids, Mayer alkaloids, Bouchardat alkaloids, Dragendorf alkaloids, tannins, and saponins. Based on GC-MS analysis of young leaves and mature leaves of R. multicolor, a total of 31 metabolite compounds from 21 compound groups were identified, with the major compound being squalene from the terpenoid group, which has the potential to be an antioxidant, anticancer, antibacterial, antifungal, antitumor, and cardioprotective.
