Various champaca plants in Indonesia have not been studied as one of Indonesia's biodiversity that can be used as excellent genetic resources (germplasm). The objective of the study was to determine the genetic diversity of champaca in Bali. The results revealed that 12 (twelve) champaca accession morphologically was characterized. All of accessions obtained from cultivation centers champaca in Bali. Based on the characteristic was observed by morphological characters i.e.: (a) Cempaka Putih Wilis (b) Cempaka Putih Pateh, (c) Cempaka Putih Patemon, (d) Cempaka Putih Sibang, (e) Cempaka Kuning Muda Petemon, (f) Cempaka Kuning Kecil Patemon, (g) Cempaka Kuning Besar Patemon, (h) (i) Cempaka Kuning Kecil Sibang, (j) Cempaka Kuning Tua Sibang, (k) Cempaka Kuning Muda Sibang, and (l) Cempaka Kuning Punah Sibang. Morphologically, champaca in Bali can be grouped into 4 clusters and therefore, and based on RAPD analysis champaca in Bali could be grouped into 5 clusters.

  • Magnolias in Thailand
    sssssa $2 MAOssOLIA Magnolias in Thalland- a growerss point of view Thlnokom Komkns To ordinary Thai people who are just interested in plants, Magnoliaceae is known as a group of scented flowering trees and shrubs called "Champee" or "Champs" which are the common names for the similar and widely cultivated Magnolia x alba (white flowered) and Magnolia champaca (orange flowered). When gmwn near houses, these trees can perfume the whole compound during the flowering sea- son. Most magnolia enthusiasts, including me, must admit that in the beginning, we may not care so much for these local cultivated magnolias as they are not very spectacular and there are so many other fragrant flowering trees to choose from instead. However, as I learned more about magnolias, I became increasingly at- tracted by their beauty, especially of the exotic temperate magnolias that were aro- matic, as well. That these temperate magnolias are closely related to our Champee and Champa (which were formerly c)asstfied in the genus Michelia) made me even happier since these and our local magnolias can be grafted together. Such grafting helps us grow the temperate cultivars here in the tropics and lights up our hope that someday we may develop a hybrid with heat tolerance as well as beauty. That The author, Thinokom Komkns (right), in his garden/nursery wah Hans Nooteboom. 22 ~ sAetaoLIA issue 81 is how serious growers, like myself, became interested in all magnolias available to us. I would need to write a whole book if I were to discuss each individual cul- tivar, so I would prefer to group my magnolias in my own way and discuss each group from my point of view as a grower —hrst with my local magnolias and lat- er with the imported exotics.

  • Magnolia 'Mon Champa'
    ISSUE 86 MAGNOLIA Magnolia 'Mon Cham/a' My Ultimate Yellow Magnolia 5orho Suesotcha I am just a magnolia enthusiast without any background in botany or horticul- ture living in the tropical country of Thailand. My location is approximately goo miles (48o kilometers) north of Bangkok. It's a typical lowland, elevation 6Soft (zoom), with a not-so-hunud tropical climate where it is too warm for most of the magnificent colorful temperate magnolias. This limits my ability to grow any more than a few species and cultivars of both local (especially the hill spe- cies) as well as the exotics (including a few subgenus Yn lani a cultiva rs). Thus, I have concluded that if I want more diversification in my collection, I will have to attempt to create hybrids among my own tropical species and culti vers and/ or with the exotics. So, I began to get serious about this about four years ago and now I'm beginning to see some results. By luck, the first one that has flowered is very encouraging: a yellow hybrid of which I am rather proud and consider to be an ultimate yellow. It's a cross be- tween Mngnalia liliifi rn var. liliifcra (known locally as Montha) and (Mngnalin champaca (known locally as Champs). Unlike, most of the temperate yellow magnolia cultivars that obtain their creamy or pale-yellow pigmentation from M. ncnminnln, the yellow in this new hybrid is a bright or golden yellow. My magnolia friends who have more botanical background than I would not expect that I could make this cross and they themselves probably would have never attempted it.

M. champaca belonging to family Magnoliaceae is an evergreen tree mainly cultivated in Indian gardens and near temples for its fragrant flowers and handsome foliage. Its highly distributed in eastern Sub-Himalayan tract, West Bengal, Mayanmar and South India in addition to China. It is noted for perfumery and envisaged as ‘Joy perfume tree’. ‘Joy’ the second bestselling perfume in the world is derived in part from the essential oil of champaca flowers. Champaka finds its utility in ethnomedicine like bark is diuretic, febrifuge and flowers, fruits are anti-spasmodic, stomachic and also in commercial industries. Flowers are the source of Champa oil, used in perfumery, in preparation of attars and perfumed hair oils.

    THAI FOR. BULL. (BOT.) 37: 111–138. 2009. The Magnoliaceae of Thailand HANS PETER NOOTEBOOM1 & PIYA CHALERMGLIN2 ABSTRACT. The Flora of Thailand treatment in 1975 recognised eight genera and 13–16 species in Thailand. Morphological studies and research using DNA sequence data, including nuclear DNA, have shown that only one genus occurs in Thailand, Magnolia L. Since 1975 many more species have been found to occur in Thailand, both newly described taxa and new records. Thus a new treatment for Thailand is presented recognising 25 species in a single genus, Magnolia. Keys are given to flowering and fruiting material, and synonymy, descriptions and supporting information provided. KEY WORDS: Magnolia, Magnoliaceae, Thailand, taxonomy, keys.

Revised: 08 February 2013 ; Accepted: 13 March 2013 Abstract: Magnolia champaca is a culturally important of the Eastern subHimalayan region as well as the tree in the tropics with a high commercial value. Its natural Western Ghats (Troup, 1921; Hossain & Nizam, 2002). regeneration is rare. Hence, the species is usually propagated It is extensively planted in other parts of tropical from seeds but with great difficulties. The class of dormancy Asia (Sri Lanka to Indonesia, Vietnam and China) in M. champaca seeds has been reported to be physical, and cultivated in tropical Central and South America physiological, and morphological. Their storage behaviour and Africa (Candiani et al ., 2004; Orwa et al ., 2009; as orthodox, intermediate, and recalcitrant has been reported by various authors. During the present research, seeds of Tropicos®, 2012). Magnolia champaca is well known this species in Sri Lanka were collected to determine their for its sweetly scented flowers (Armiyanti et al ., 2010), dormancy class and storage behaviour. Both scarified and and various parts of the plant provide fodder, timber, nonscarified seeds imbibed water; however, high germination fuel, medicines, and antifungal compounds (Orwa et al ., occurred only on gibberellic acid (GA 3) showing the presence 2009).
