BACKGROUND The low survival rate of in vitro regenerated Panax ginseng plantlets after transfer to soil is the main obstacle for their successful micropropagation and molecular breeding. In most cases, young plantlets converted from somatic embryos are transferred to soil. METHODS In vitro thickened taproots, which were produced after prolonged culture of ginseng plantlets, were transferred t...

The perfoliate pondweed Potamogeton perfoliatus constitutes large mono-specific macrophyte patches in many Central European lakes. Correlative evidence from the field suggests that Potamogeton is under an increasing grazing pressure during its short vegetation period from May to September due to seasonal outbreaks of the aquatic moth Acentria ephemerella. We used a mesocosm experiment to determ...

Different planting techniques influence the quantitative and qualitative characteristics of sugarcane. This study focused on hypothesis that altering sett spacing bud placement position significantly improves sugarcane yield quality. The experiment was conducted during periods, 2016–2017 2017–2018, under field conditions at Sugarcane Research Institute, Agriculture Centre, Tandojam, Sindh, Paki...

An efficient, simple micro propagation method was developed for Zingiber officinale Rosc.) cv. Volvo using fresh sprouting bud in basal culture media. Explants were cultured on to Murashige and Skoog’s (MS) medium supplemented with different concentrations combinations of BA (Benzyl adenine) KIN (Kinetin) shoot IBA (Indol-3-Butyric acid) NAA (α- Naphthalene acetic root induction. MS 2.0 mg/L + ...

Gardenia plants have long been used as traditional medicines in various countries including Thailand. In this study, two new 3,4-seco-cycloartane triterpenes, sootependial (1) and sootepenoic acid (2), were isolated from bud exudate of G. sootepensis, together with five known compounds. Their structures were elucidated on the basis of spectroscopic data. Sootependial (1) showed potent cytotoxic...
