Opis:
Pretreatment of mungbean (Vigna radiata) seeds with leaf extract of tulsi (Ocimum sanctum) for 4 hours before accelerated ageing treatment (99.5% RH and 32±2oC) for different durations for 30 days slowed down the ageing-induced rapid loss of seed germination. Plant performance was found to be much better developed from seeds which underwent plant extract pretreatment measured in terms of few reliable indices. Plant potential was also higher in the pretreatment as evidenced from the treatment-induced higher chlorophyll level as well as activity of catalase enzyme. Results, therefore, pointed out that the plant extract-pretreated seeds retained higher seed vigour and produced healthier plants inspite of experiencing accelerated ageing treatment.

Opis:
Synthesis of nanoparticles using plant leaf extract is an eco-friendly, non-toxic and cost efficient approach in the field of nanotechnology. In this study, biosynthesis of stable copper nanoparticles were prepared by using Ocimum sanctum and Piper nigrum extract. These biosynthesized Cu nanoparticles were characterized with the help of X-Ray diffraction (XRD), Scanning Electron Microscopy (SEM) and Fourier transforms infrared spectroscopy (FTIR). The crystalline size of the Copper Nanoparticles prepared from Tulsi extract is little smaller than Copper nanoparticles prepared from Pepper extract. SEM images of Copper nanoparticles showed that the cluster formation, presence of smaller and larger grains. FTIR analysis revealed that the functional groups present in the Copper nanoparticles prepared from both Tulsi and Pepper extracts. Thus, this method can be used for rapid and ecofriendly biosynthesis of stable copper nanoparticles and can be used for catalytic agent, anti-microbial, anti-fungal, anti-biotic, nanosensor, super conducting material, solar cell applications.

Opis:
In August 2015, twig blight disease of ban tulsi (Croton bonplandianus Bail.) caused by Choanephora cucurbitarum (Berk. & Ravenel) Thaxt. was observed for the first time, in the Gangetic alluvial region of West Bengal, India. A severe disease incidence (40–50%) showed twig blight symptoms starting with shoot apical meristem (SAM), leaf, and blossom blight symptoms. Typical symptoms were characterized by over-projecting black pin head like emerging sporangiola which formed mycelial cushion on the infected surface. The present report describes the identification of the causal pathogen as C. cucurbitarum based on its morphology and the internal transcribed spacer of its ribosomal DNA (rDNA – ITS) sequences with 100% identity of NCBI-GenBank published Choanephora database. Optimum temperatures, 28–30°C, coupled with high relative humidity (80–90%) during the monsoon season enhances the disease’s progress. To the best of our knowledge this is the first report of twig blight of C. bonplandianus, caused by C. cucurbitarum, in India as well as globally.
