Abstract

Hibrida antara Solanum khasianum CLARKE dan S. capsicoides ALL. berhasil diperoleh dengan persilangan dan fusi protoplas. Tujuan penggabungan kedua jenis tersebut adalah untuk memperoleh hibrid fertil dan  tahan terhadap penyakit layu bakteri yang disebabkan oleh Pseudomonas solanacearum. Karakter ketahanan ini diperoleh dari S. capsicoides. Hibrida seksual diperoleh melalui penyelamatan embrio, tetapi hibridnya steril, sehingga dilakukan penggandaan kromosom, sedangkan hasil fusi protoplas adalah fertil. Pengujian lapang terhadap ketahanan penyakit layu bakteri dilakukan di daerah Bogor dan Tangerang dan hasil analisis data menunjukkan bahwa karakter ketahanan diturunkan secara kuantitatif. Faktor lingkungan berpengaruh sangat besar, sehingga heritabilitas sangat rendah.

Abstract

Mangrove area in Muara Angke was dominated by api-api (Avicenniamarina) and bakau (Rhizophora mucronata). We asume that thesespecies was able to acumulate h eavy metals, since both of them haveadapted in this environmental condition which content of highconcentration h eavy metals. The objective of this experiment was toanalyze heavy metals content in the tissue of api-api (Avicennia marina)and bakau (Rhizophora mucronata) in Muara Angke Jakarta. The resultsshowed that Cu was highest heavy metal content in root of bakau(24.431 ppm) . While 23.674 ppm of Cu was content in api-api roots. Cucontent in sediment was 26,640 ppm.

Abstract

The agroforest region is bestowed with diverse agro-climatic zones, whichmakes itself a rich storehouse of different types of Flora and Fauna.Besides, this conditions help in introduction, acclimatization, andcultivation of a number of aromatic plants with minimum efforts. Thereare a few commercial crops, which can be cultivated without disturbingthe existing flora and have the potential to establish as cash crops inthis region.Patchouli (Pogostemon cablin) has been identified as one such essentialoil bearing aromatic plant with immense export potential. Patchouli oilproduction could be a rural based, labour intensive, low cost agro-basecottage industry, which will give large-scale employment in rural and hillyareas. Patchouli, being a shade loving plant can easily be grown as anintercrop amidst fruit trees, arecanut, and coconut plantation etc. It canalso be easily cultivated in flood free fallow or wastelands. This will providesome extra income for the farmers. Following figures clearly indicatesthat Patchouli cultivation can be a good option besides the traditionalcrops.
