A study on the use of organic additives on the protocorm-like bodies (PLBS) growth of Phalaenopsis violacea orchid

The potential of different concentrations of various banana cultivars extracts, papaya extract, tomato extract and coconut water (0, 10, 20, 30%) to the control (without carbon source and plant growth regulator free medium) for reliable proliferation of Phalenopsis violacea protocorm-like bodies (PLB) under in vitro condition. The results indicated that organic extracts were taken up from the media as shown by the increased in percentage of PLB proliferation rate. Maximum growth of PLB was obtained in half-strength Murashige and Skoog (MS) semi-solid medium supplemented with 10% of Mas (AA) banana pulp extract. However, it has been noticed that at a higher concentrations of organic extract tend to be inhibitory to the PLB proliferation which could be due to the osmotic stress. PLBs grown in half-strength MS supplemented with papaya extract had the lowest PLB proliferation rate among the different organic extracts. It can be concluded that, adding Mas (AA) banana pulp extract at concentration of 10% can be a potential replacement of sucrose in the media. Therefore, the short time length of in vitro culture and its high efficiency makes addition of suitable organic extracts well suited for mass propagation of Phalenopsis violacea orchid

Agrobacterium-Mediated Transformation of the Recalcitrant Vanda Kasem’s Delight Orchid with Higher Efficiency

The presented study established Agrobacterium-mediated genetic transformation using protocorm-like bodies (PLBs) for the production of transgenic Vanda Kasem’s Delight Tom Boykin (VKD) orchid. Several parameters such as PLB size, immersion period, level of wounding, Agrobacterium density, cocultivation period, and concentration of acetosyringone were tested and quantified using gusAgene expression to optimize the efficiency of Agrobacterium-mediated genetic transformation of VKD’s PLBs. Based on the results, 3-4mm PLBs wounded by scalpel and immersed for 30 minutes in Agrobacterium suspension of 0.8 unit a

Effects Of Led On The Micropropagation And Callus Induction Of Zingiber Officinale Var. Rubrum

Micropropagation of medicinally important Zingiber officinale var. rubrum will generate infinite disease-free in vitro clones for plantation; preventing reservation of seed rhizome from harvest. Hence, the applicability of light-emitting diodes (LEDs) was determined for the micropropagation of Zingiber officinale var. rubrum
