Secretory Duct Structure and Phytochemistry Compounds of Yellow Latex in Mangosteen Fruit DORLY DORLY; SOEKISMAN TJITROSEMITO; ROEDHY POERWANTO; JULIARNI JULIARNI

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

Changes of Gibberellin and Total Sugar Content in Flower Developmental Stages of Mangosteen I NYOMAN RAI; ROEDHY POERWANTO; LATIFAH KOSIM DARUSMAN; BAMBANG SAPTA PURWOKO

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

In Vitro Growth and Rooting of Mangosteen (Garcinia mangostana L.) on Medium with Different Concentrations of Plant Growth Regulator FAUZIYAH HARAHAP; ROEDHY POERWANTO; . SUHARSONO; CICIK SURIANI; SUCI RAHAYU

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.
