Micropropagation of Homalomena pineodora Sulaiman & Boyce (Araceae): a new species from Malaysia 75
Stanly,Christine; Bhatt,Arvind; Sulaiman,Baharuddin; Keng,Chan Lai.
Homalomena pineodora (family Araceae) is a species found to have impressive foliage characteristics which remain evergreen throughout the year. Therefore, H. pineodora can be grown as an ornamental plant. Generally H. pineodora needs 3-5 years to propagate and multiply. However, the demand for new ornamental plants is increasing worldwide and the quality of planting material is a basic need for boosting productivity. Therefore an efficient micropropagation protocol for large-scale production of H. pineodora was developed. In vitro shoot cultures were initiated from the rhizomatous buds on MS basal medium. The best conditions for propagating H. pineodora was found to be MS medium supplemented with 3% sucrose and 0.5 mg L-1 BA (6-benzyladenine) under 24 h of...

In vitro propagation of five Alocasia species 75
Bhatt,Arvind; Stanly,Christine; Keng,Chan Lai.
The influence of cytokinin, N6-benzyladenine, on shoot proliferation of five Alocasia species (A. amazonica, A. cuprea, A. robusta, A. longiloba and A. chaii) was investigated. In vitro propagation of these species was established using shoot tip explants. Murashige & Skoog (MS) medium supplemented with different concentrations of BA (N6-benzyladenine) ranging from 0, 2, 5, 10 mg/L was then used to establish the optimum medium for shoot proliferation for all the species. MS medium supplemented with 2.0 mg/L BA was optimum for the shoot proliferation. All the tested species showed varying results for shoot number and shoot height. A comparison between agar-gelled medium and shake flask system using liquid medium was carried out to evaluate the shoot...

Maternal habitat affects germination requirements of Anabasis setifera, a succulent shrub of the Arabian deserts 39
El-Keblawy,Ali; Gairola,Sanjay; Bhatt,Arvind.
The effects of maternal habitat on light and temperature requirements during germination were assessed for the succulent desert shrub Anabasis setifera. Seeds were collected from the Mediterranean habitats of Egypt and the hyper-arid subtropical habitats of the United Arab Emirates (UAE). Seeds from the two populations were germinated in three temperature treatments in both a light/dark regime and continuous darkness. Seeds from the Egyptian population germinated significantly greater and faster than those of UAE. Seeds stored for four months at room temperatures have little dormancy and germinate at wide range of temperatures and light conditions, but seeds stored four months in the natural habitat lost their ability to germinate and rotted 10 days after...
