Gabriel<br/><br/> The study on the Germplasm Collection and Evaluation of Lantana camara in<br/>Selected Municipalities of Ilocos Norte was conducted in five municipalities of the<br/>province of Ilocos Norte, namely, Pagudpud, Bangui, Burgos, Adams and Dumalneg<br/>from December 2018 to January 2019. Twenty-two accessions were randomly<br/>selected. The study aimed to a) characterize Lantana camara grown in selected<br/>municipalities of Ilocos Norte; b) determine the variability of Lantana camara grown<br/>in selected municipalities of Ilocos Norte; c) identify lantana plants with outstanding<br/>flowering characteristics as ornamental plant; d) establish germplasm collection of<br/>different varieties of lantana; and e) develop a descriptors list for Lantana camara.<br/>Results showed that most (59.09%) of the lantana plants were grown in the<br/>roadside. Furthermore, all of the lantana plants were located in a flat area. Most<br/>(59.09%) of the lantana plants were grown at the roadside areas, compared to 40.91%<br/>that were grown at grassland. Result also showed that all the accessions were grown<br/>in the wild. Further, the growth habit of the sample plants was spreading.<br/> On the other hand, it was observed that the leaves of the sample plants were<br/>all the simple type. In addition, 57.55% of the plants exhibited intermediate leaf<br/>length of 5-6 cm. Findings also showed that leaf shape of the lantana generally<br/>exhibited ovate leaves (50.00%) and cordate (45.45%). However, the leaves of the<br/>plants were arranged in opposite manner. For the leaf apex, results showed that most<br/>(77.27%) were acute. Moreover, leaf margin of the sample plants were all serrate.<br/> The lantana plants generally exhibited a rounded (50%) and cordate (40.91) leaf base.<br/>In this study, majority of the studied sample flowers of the lantana plants<br/>exhibited pink color (45.45%). These accessions were widely distributed in all the<br/>selected municipalities studied. Furthermore, lantana plants with outstanding<br/>flowering characteristics as ornamental plants were identified in eight different color<br/>types, namely, pink, ornamental orange, white, ornamental white, pink with yellow<br/>orange, ornamental yellow, red, and pale pink with yellow. These accessions were<br/>considered promising ornamental plants, which showed potential characteristics that<br/>can be used for further evaluation for possible registration as commercial variety.<br/>Inflorescence characteristics were noted wherein, the flower shape and<br/>inflorescence type of the different accessions were identified as salverform and<br/>simple umbel, respectively. Moreover, the size of the floret ranged from 0.7-1.5 cm<br/>with a mean of 1.15 cm and it was noted that 86.36% generally exhibited<br/>intermediate. Results also showed that most (54.55%) were generally medium in the<br/>number of florets per cluster. Fruit color of the lantana plant was noted. The fruits were green when unripe<br/>and black when ripe. Results also showed that fruit of lantana was identified as berry.<br/> <br/> |
