An experiment was conducted to access the effect of pedicel retention and storage of malta fruits in zero energy cool chamber (ZECC). It was observed that there was an increase in the physiological loss in weight and TSS of the fruits during 90 days storage, while, the fruit firmness and titratable acidity declined consistently during the entire storage period. These changes were minimum in the fruits harvested with pedicel and stored under ZECC. The weight loss and the rotting were reduced to about half by storage of fruits in ZECC. The shelf-life could be enhanced to about 90 days by storing the fruits in ZECC with attached pedicel.

An experiment was conducted for induction & establishment of Agrobacterium mediated hairy root culture of Coleus forskohlii was developed & co-cultivation on hormone free semisolid MS Medium with B5vitamins.Sterilization period was standardized for the stem & leaf explant using 0.1% bavistin and 0.1% Hgcl2 with varied intervals It resulted in the emergence of hairy roots from the leaf explant , stem explant after 20th day of infection .The transformation of hairy roots was established and confirmation of forskolin content was done by HPLC. Selection of high forskolin can provide an alternative source of large scale production of forskolin.

Mulberry leaf exclusively assures the growth and development of the silkworm larvae, being considered a complete value nutrient, so that the knowledge of its nutritional status is of great interest. The nutritional status of different mulberry varieties is ascertained by its biochemical constituents. Mulberry is rich sources of protein, carbohydrate, carotenoids, lipids, ascorbic acid, anthocyanins etc. Hence the current investigation was undertaken to study the biochemical constituents in different parts viz, roots, leaves and fruits of seven mulberry genotypes. The results indicated that AR-12 mulberry variety have recorded highest biochemical constituents.

The changes of growth pattern and anthocyanin production, malvidin and delphinidin of Malva sylvestris L., were studied under UV-B treatment. The supplemental dose of UV-B exposure significantly reduced the growth of the plant with increase in anthocyanin content. With the traditional chilled acidified methanol method, the total anthocyanins were extracted and estimated by pH differential spectroscopic method. The anthocyanins were purified by C18 Sep-pak column and further analyzed for different anthocyanins by high performance liquid chromatography (HPLC) methods.

Jatropha curcas is a multipurpose bush or a small tree belonging to the family of Euphorbiaceae is gaining lot of importance for the production of biodiesel. It is a plant with many attributes, multiple uses and considerable potentials. It is a tropical plant that grows up to a height of 3 - 5 meters and has a productive life of 50 years. It is resistant to a high degree of drought (it can be plant even in the wasteland) and as such does not compete with food crops. The seeds contain 40% oil that can be processed to produce a high-quality biodiesel fuel, usable in a standard diesel engine. Seeds are ready for harvesting around 90 days after flowering when the fruits have changed from green to yellow-brown colour. The harvesting of the Jatropha fruits is a difficult process due to the ripening characteristics of the Jatropha fruits. Harvesting machinery has been developed in order to harvest the Jatropha fruit, but the machine is not only harvest the fruit but also damaging the tree. Leaves, twigs and unripe fruits were harvested together with a low percentage of ripe fruits. To solve this problem, this study is being conducted to find the best vibration frequency for the ripe fruit to detach upon being shaken by a mechanical device without detach the unripe fruit and damaging the tree.
