Evaluation of Cytotoxicity of the Aqueous Leaf Extract of Pogostemon Heyneanus Benth. (Java Patchouli)

Several plants have been recently reported to possess anticancer potential. Allium cepa root tip assay is a preliminary study to assess the cytotoxic effect of plant extracts. The cytotoxic activity of plants can be correlated to their anticancer potential. Cytotoxic potential of Pogostemon heyneanus (Lamiaceae) was evaluated using A. cepa root meristematic cells. This study was aimed at analyzing cytotoxic potential of P. heyneanus using Allium cepa root tip assay. Four different concentrations of the aqueous leaf extracts at three different durations were examined. Distilled water was used as control. The extract was found to be cytotoxic at all tested concentrations, when compared to control. Mitotic index was found to be decreasing with the increase in extract concentrations and treatment durations. The aqueous extract of P. heyneanus was found to be an effective cytotoxic agent, inducing various clastogenic and non-clastogenic aberrations such as chromosome gaps, bridges, multipolar anaphase, fragments, nuclear budding and lesions, hyperchromasia, laggards and mitotic pairing.

Histological Analysis of in Vitro Cultured Coconut Endosperm

Coconut is a very important plant for the livelihood of people in tropical countries. It is also used as an icon of tropical region. Coconut fruit is very heavy and can cause injuries if the fruit falls down and hits somebody who happens to be underneath a coconut tree. In order to avoid the accident, the coconut fruits have to be regularly cut off. Coconut tree originated from in vitro cultured endosperm is a triploid plant that produces seedless fruit (without endocarp). Coconut fruit without endocarp is not heavy. The objective of this study was to investigate plant regeneration of fresh and in vitro cultured coconut endosperms. The fresh and developed in vitro cultured coconut endosperms were observed using histological analysis. Solid endosperm of seven month-old postanthesis coconut from “Samoan Dwarf” cultivar was freshly picked up and cultured in vitro on modified Branton & Blake formula. Histological study of fresh coconut endosperm showed that the endosperm consisted of parenchyma cells, which were relatively uniform in shape and size, with some nuclei consisted of 1 – 5 nucleoli. Three month-old calli of in vitro grown coconut endosperm in semi solid media showed that its cells varied in shape and size, characterized by high nucleus to cytoplasm ratio, high starch, protein and lipid contents which underwent many divisions. Seven month-old calli of in vitro grown coconut endosperm in liquid media showed embryogenic cells which resembled proembryos. Fourteen month-old bud-like structure of coconut endosperm in semi solid media showed a meristematic layer, tunica-corpus structure, cortex-like region and tracheids of xylem. These results indicated that the bud-like structure was an early stage of shoot bud formation in coconut endosperm. This is the first report of early stage of shoot bud formation occurring on coconut endosperm cultured in vitro.

Pollination Effectiveness of Apis Cerana Fabricus and Apis Mellifera Linnaeus (Hymenoptera: Apidae) in Jatropha Curcas L. (Euphorbiaceae)

Pollinators are well known to provide key ecosystem. Animal pollinators are thought to contribute between 15 and 30% of global food production and bees are recognized to be the most important taxon. The pollination effectiveness of two species of bees, Apis cerana and A. mellifera (Hymenoptera: Apidae) in Jatropha curcas (Euphorbiaceae) was studied. Three cages, made of insect screen were set up. Each cage contains three individual plants. One colony of A. mellifera and A. cerana were placed in the first and second cage, while the third cage was used for control plants. Bee colonies were placed during one month in the first and second cages. Fruit set of plants pollinated by A. mellifera, A. cerana, control plants, and open plants were counted and compared. Pollination by honeybees increased the number of fruits per plant and fruits per raceme of J. curcas. Based on measuring of fruit produced by plants, pollination effectiveness of A. mellifera was higher than A. carana.
