Seed propagation of Mycetia balansae Drake is not easy, due to low germination rate and low viability, so it is very rare in nature. In order to conserve this plant as well as to use for commercial purposes in cooperation with Tue Linh Co.Ltd, providing a large number of plants is necessary and in vitro tissue culture technology could be solve this problem. Therefore, the study on "Callus induction and plant regeneration in vitro from leaf explants of mycetia balansae drake" was carried out.

This study was carried out to evaluate the effect of Cobalt chloride (CoCl2) on cardiac mitochondrial function in an in vitro model. In the study, H9C2 cardiomyocytes were cultured in a medium containing different concentrations of CoCl2. Cell viability, cardiolipin content, mitochondrial function, and mitochondrial oxidative stress were assessed by using Cell Counting Kit-8 and suitable fluorescence kits.

In this study, we investigated four factors to improve the hairy root induction in Urena lobata L. These factors include: age of plant (15-day-old in vitro plants, 45-day-old in vitro plants and after two subculture generations plants), different parts of plant (roots, stems, and leaves), infection time (10, 20 and 30 minutes), and culture medium (Murashige and Skoog (MS), Gamborg B5 medium (GB5) and Woody plant medium (WPM)).

Với các ưu điểm vượt trội của cây Keo lai so với các loài cây lâm nghiệp khác mà hiện nay loài cây này chiếm phần lớn trên diện tích trồng rừng của Việt Nam. Từ đó nhu cầu về giống cho trồng rừng là vô cùng lớn. Tuy nhiên việc nhân giống bằng các phương pháp truyền thống như giâm hom, gieo hạt không đáp ứng được nhu cầu về cây giống sạch bệnh, đồng đều về phẩm chất. Cùng với những kết quả về cải thiện giống, công nghệ nhân giống bằng phương pháp nuôi cấy mô (tissue culture) được xem là giải pháp công nghệ hàng đầu để duy trì chất lượng di truyền của cây giống.

Pre-requisite for any plant biotechnological approach is development of an efficient plant regeneration system in that crop. In this regard the in vitro regeneration was achieved by using cotyledon explants from aseptically raised seedlings of popular Capsicum F1 hybrids Bharat and Indra. Seeds of both hybrids were exposed to different treatments for proper germination, were decontaminated and sown in vitro on half-strength MS medium.

Three bio-agents i.e. Trichoderma viridae, Trichoderma harzianum and Trichoderma aspergillum were evaluated against Botrytis cinerea under in vitro condition. Culture disc of fungal bio-agents and pathogen were taken from the growing cultures and transferred to PDA contained in 70 mm petridishes on opposite sides approximately at one cm from the wall of the plate. Among these three bio-gents Trichodema harzianum showed best mycelial growth inhibition of Botrytis cinerea.

Foot rot of tomato is an important disease which causes severe loss in tomato production. The present study was carried out to evaluate five bioagents and six fungicides against Sclerotium rolfsii. Among the five antagonists tested the maximum inhibition was observed in Trichoderma virens (67%) and contrarily, no inhibition was observed in Bacillus subtilis. Six fungicides viz., carbendazim, captan, tebuconozole, copper oxychloride, hexaconozole and Tebuconazole +Trifloxytrobin at different concentrations (50, 100, 150, 200, 250 and 500 ppm), were tested.

Among the diseases of safflower; dry root rot disease caused by Macrophomina phaseolina (Tassi.) Goid is one of the most destructive and wide spread disease of Safflower (Carthamous tinctorius L.) causing accountable losses of about 25-60 per cent. Eleven Botanicals evaluated in vitro were found fungistatic/antifungal against M. phaseolina. Amongs these A. sativum followed by A. cepa and V. negundo caused significantly highest mean mycelial inhibition 83.57, 72.09 and 65.85 per cent respectively.

An efficient lighting system (Compact 3U) was successfully applied to the micropropagation of gloxinia and potato plants. To compare the in vitro growth of plantlets under Neon and Compact 3U lighting systems, gloxinia and potato shoots were cultured on suitable media at different light intensities: (1) 45 µmol m-2s -1 (under Neon lighting system as a control); (2) 45 µmol m-2s -1, (3) 60 µmol m-2s -1, and (4) 75 µmol m-2s -1 (under Compact 3U lighting systems).

Litchi is considered a crop difficult to propagate through micropropagation and obtaining contamination free cultures is first and foremost requirement of tissue culture. So the present investigation was carried out to standardize the sterilization procedure of nodal segment and leaf explants of Litchi chinensis Sonn. cv. Purbi. Two surface sterilizing agents viz. HgCl2 and NaOCl were used at varying concentrations and durations.

The results showed that protocorms were formed from seeds culture on the ½ MS medium supplemented with 10% potatoes extract within 8 weeks. Protocorms which were cultured on the ½ MS medium containing 30 g/l sucrose, 0.5 g/l AC, 7 g/l agar, 0.1 mg/l NAA and 1 mg/l BA were optimal for PLB formation (8.67 PLBs/sample) after 8 weeks culture. Protocorms converted into normal plants with well-developed shoots and roots on the ½ MS medium supplemented with 20 g/l sucrose, 10% potatoes extract, 0.5 g/l AC, and 7 g/l agar after about 90 days.
