This study aimed to evaluate the sensory attributes such as aroma, color and texture of kaffir lime leaves in response to various post-harvest treatment. The hedonic test approach was conducted by inviting 70 untrained panelists on seven post-harvest treatments, i.e. (D1) post-sortation fresh leaves, (D2) pre-sortation fresh leaves, (D3) cold-storage leaves, (D4) low temperature-storage leaves, (D5) brown dry leaves, (D6) fresh leaf-flour, and (D7) brown dry leaf-flour. The result showed that most of panelist agreed that aroma was the most important quality attribute that determined the level of preference in kaffir lime leaf products. Among seven tested products, the aroma, color, texture and overall impression of D1 was the most favorite one, while D4, D5, and D7 were assessed as low preference products. This work showed the importance of sortation and cold storage to maintain consumer likeliness. The criteria for sortation were green, clean, pest-disease free, scar free, high uniformity and fresh condition of leaves. Cold-storage at -20oC maintained the color and texture of kaffir lime leaves better than low temperature storage (5oC). To make leaf flour, the use of fresh green leaves was significantly better than brown dry ones. This finding might become the baseline data for the development of kaffir lime leaf product in the future.

Kaffir lime (Citrus hystrix DC) is a less popular citrus species commonly used as a food spice and a source of essential oil. Early studies report the success of preharvest mild shading to increase leaf yield, although there is still limited information on the effect of preharvest shading on the quality of essential oil produced. The aim of this current study is to evaluate the effect of preharvest mild shading factors on the yield, physical characteristics, and metabolite fingerprinting of kaffir lime leaves essential oil (KLLEO). One-year-old kaffir lime trees were sampled in two preharvest treatments, i.e., open sun and mild shading (24% light reduction) at Pasir Kuda experimental field, Bogor, Indonesia. Statistical analysis showed that there was no significant effect of preharvest treatment on yield and physical characteristics (color, specific gravity, and refractive index) of KLLEO. In contrast, there was a metabolite fingerprinting variation of KLLEO as an effect of mild shading. The relative percentage of bergamol, citronellol, caryophyllene oxide, citronellic acid, isopulegol, isopulegyl formate, limonene, linalool, and linalool oxide was increased by mild shading. On the other hand, the main metabolite (citronellal) was significantly reduced by about 10% in shading treatment, as compared to the open-sun ones.

Yellow latex is the main problem in mangosteen agribusiness, because it is one factor lowering the fruit quality. The structure of yellow latex secretory ducts in the flower and fruit as well as in the root, stem and leaf of mangosteen (Garcinia mangostana L.) seedling and the qualitative phytochemistry of yellow latex were studied. The ducts were branched, canal-like type. They were found in the exocarp, mesocarp, endocarp, aril of the fruit, flower, stem, and leaf. In the fruit, the biggest diameter of the secretory ducts was found in the endocarp. There were continuous secretory ducts from fruit stalk to the fruit. Ultrastructural observation showed that the ducts surrounded by specific epithelial cells, which were living cells containing dense cytoplasm with plastid, mitochondria and golgi apparatus organelles. The qualitative test indicated that the yellow latex collected from stem bark, outer part of fruit, young fruit pericarp, mature aril and young aril contained terpenoid, flavonoid and tannin, but not alkaloid, saponin and steroid, except in the young aril containing the steroid. Key words: secretory ducts, yellow latex, endocarp, aril, epithelial cells

The objectives of this experiment were to study the changes of gibberellic acid and total sugar content in flower developmental stages of mangosteen. The result showed that flower development of mangosteen consisted of four stages: induction, differentiation, maturition of flower organs, and anthesis. Floral induction was microscopically characterized by the swelling of the basal structure of the new shoot. It was found that induction stage of mangosteen flowering was characterized by sharp decrease of gibberellic acid (GA3, GA5, GA7) and increase of total sugar content of leaf. On the other hand, it was found that leaf of the non-flowering shoot apices had high gibbrellic acid and low total sugar. Key words: mangosteen, flowering, induction, gibberellic acid

Propagation of mangosteen is challenging for many reasons, including limited seed set, slow rate of seedling growth, and difficulty with root formations. The objective of this research was to find the best combination of medium and plant growth regulator for in vitro growth and rooting of mangosteeen seed. Various types of explant (a whole seed; seed divided into 2, 3, and 4 cross sections; seed divided into 2, 3, and 4 longitudinal sections) were treated with five concentrations of benzyl amino purine (BAP; 0, 2.5, 5, 7.5, 10 mg/L) for shoot induction in ½ Nitrogen (N) Murashige and Skoog (MS) medium. The shoots were rooted on MS and woody plant medium (WPM) media with several combinations of indole butyric acid (IBA) and naphtalene acetic acid (NAA). Treatments for root induction were applied as follows: (i) low dose, given during induction of rooting, (ii) soaking the base of the shoots in medium treated with a high dose of auxin for 5 days, and then growing the shoots in MS ½ N with 1 mg/L NAA + 1 mg/L BAP medium. Our result show that BAP positively affected mangosteen bud growth. The best medium for mangosteen shoot regeneration was found to be MS ½ N + 5 mg/L BAP. This medium induced the highest number of shoots from the seed explant cut into four cross sections. We found the best medium to induce in vitro rooting of mangosteen shoot was MS ½ N + 3 mg/L indole butiric acid (IBA) + 4 mg/L NAA medium. Some treatment negatively affected growth. Soaking the mangosteen shoot base in a medium with an overly high dose of auxin seemed to disrupt and inhibit growth of the mangosteen shoot.

Growth of mangosteen essentially depends on its root system. Therefore, it needs technology to obtain stringer mangosteen root system. The use of Agrobacterium rhizogenes bacterium is an alternative. The objectives of this experiment were : 1) to find the effective strain of A. rhizogenes bacterium for inoculation of mangosteen seedling root, 2) to find the best inoculation method for inducing mangosteen seedling root. The materials used in this experiment were ; mangosteen fruit and A. rhizogenes collection from Puslit Biotechnology LIPI Cibinong-Bogor. The experiment was arranged in completely randomized design with two factorial treatments. The first factor : 11 strains A. rhizogenes (ATCC-15834, ATCC-8196, R-1000, 07-20001, A4, A4-J, 509, 510, 511, MAFF 01-1724, and control), the second factor : 2 inoculation methods (cutting and dipping). The results showed that A. rhizogenes of ATCC-15834, 509, 07-20001, A4, and R-1000 increased stem diameter, plant height, leaf number, lateral and tertiary root number, better than ATCC-8196, MAFF 01-1724, 510, 511, A4-J, and control. Cutting root method of inoculation resulted in higher live plant percentage compared to dipping root method. Key words : Agrobacterium rhizogenes, Garcinia mangostana, inoculation

A number of Trichosanthes species has been reported as a source of bioactive protein associated with defense mechanisms such as chitinase. Chitinase and peroxidase of crude protein extracted from leaves, roots, in vitro calli and shoots of T. tricuspidata had been analysed. Calli were induced on MS medium containing combinations of 1 µM NAA + 1 µM BA (K1), 2 µM NAA + 2 µM BA (K2), 3 µM NAA + 3 µM BA (K3), or 4 µM NAA + 4 µM BA (K4). Shoots were cultured in MS with 1 mg/l of BA, while leaves and roots were harvested from six-month old plants grown on the field. Results of the experiment suggested that K1-K4 medium could be used to induce calli although weight of calli from all medium composition was not significantly different (0.19-0.31 g/explant/4 weeks). Calli from K1 medium had the highest of total crude protein content (3.24 mg/ml). The highest of chitinase activity was found in in vitro shoots (6.51 mM pNP/hour/mg protein) and the highest peroxidase activity was in the plant roots (0.25 ∆ 420/minute/mg protein). Key words: in vitro calli, shoots, crude protein, chitinase and peroxidase activities
