Coleus forskohlii is an important indigenous medicinal plant in India. It has been used in traditional Ayurvedic medicine for curing various disorders and this is the only source of the diterpenoid forskolin. Forskolin is used for the treatment of eczema, asthma, psoriasis, cardiovascular disorders and hypertension, where decreased intracellular cAMP level is believed to be a major factor in the development of the disease process. A comprehensive account of the morphology, distribution, medicinal uses, phytochemistry, pharmacological activities, analytical methods, cultivation aspects and biotechnological approaches for forskolin production reported are included in view of the many recent findings of importance on this plant. © 2009 Academic Journals.

A field experiment was carried out at HC & RI, Anantharajupet, Y.S.R. district, Andhra Pradesh (India) during the winter season of 2013-2014. December 10th planting was recorded maximum plant height, plant spread, number of leaves per plant and less number of days to flower bud initiation and high yield/ha. January 20th planting was recorded less number of days to first and final harvest and chlorophyll content. Among the plant geometries, 60 x 45 cm recorded maximum values for plant spread, number of leaves per plant, ascorbic acid content and chlorophyll content. While, 50 x 30 cm geometry was noticed highest plant height, yield/ha and less number of days to flower bud initiation. Interaction of dates of planting and geometries were significantly recorded maximum plant height and yield/ha in December 10th planting with spacing of 50 x 30 cm, whereas December 10th planting with a spacing of 60 x 45 cm was noticed maximum number of leaves per plant. While, January 20th planting with a spacing of 60 x 45 cm recorded highest chlorophyll content. © 2014, Plant Archives. All rights reserved.

Evaluation of the growth and sporulation Nomuraea rileyi isolates on different health drinks sources media showed potato maltova agar was significantly superior to other media and supported the maximum biomass, mycelial growth and conidial count. In case of PDBC isolate, among the six different health drinks sources tested, the maximum radial growth, biomass and spore production were observed in potato maltova agar medium both in solid as well as in the liquid medium. Similar trend of growth and development was observed with DOR and local isolates of N. rileyi. © JBiopest.

Pollen studies were conducted in ten single type genotypes of tuberose (Polianthes tuberosa) viz., Shringar (Mexican Single x Pea Double), Prajwal (Shringar x Mexican Single), Phule Rajani (Mexican Single x Shringar), Calcutta Single, Hyderabad Single, Kahikuc Single, Mexican Single, Pune Single, Navsari Local and Variegated Single at TNAU, Coimbatore, India. Studies revealed that polle grains were round in shape, pollen viability in acetocarmine stain was 96.73% in the genotype 'Variegated Single' and the germinatio was maximum (99.21%) in 15% sucrose solution with other chemicals. Pollen tubes grew to a length of 1234.949 microns 24 hou after the dehiscence of anther. Among the genotypes under study, the highest fruit set was 89% under natural open pollination and 0 under artificial self pollination.

The production of lateral shoots for vegetative propagation in papaya is a limiting factor due to apical dominance. To overcome this problem, the effect of plant bio-regulators viz., GA3 and BA were investigated, on eight months old field grown papaya trees of cv. CO.2 in induction of lateral shoots, to be used as scion for grafting in papaya at Tamil Nadu Agricultural University, Coimbatore (Tamil Nadu), India during 2011. Among the treatments, it was revealed that BA 250 ppm produced a higher number of 42.00 buds per plant at 20 days after spraying. In respect of number of graftable sized scion laterals, plants sprayed with GA3 125 ppm + BA 125 ppm registered the maximum of 21.50 nos in CO.2 at 20 days and 17.50 nos in 35 days after spraying. © 2014, Plant Archives.

An experiment was conducted during kharif 2012-13 at Horticultural Research Station, Lam, Guntur, Andhra Pradesh (India) to identify potential genotypes for ten quantitative traits among sixty three genotypes of chilli (Capsicum annuum L.). The analysis of variance revealed significant differences among the genotypes for all the ten characters indicating the presence of genetic variability among the genotypes. Among sixty three genotypes, the genotype LCA-720 recorded maximum plant height whereas the genotypes, Pusa Sadabahar and Pandava recorded the highest number of primary branches per plant. The genotype LCA-709 recorded earlier flowering while the maximum fruit set per cent was observed for LCA-746. The genotype LCA-706 recorded maximum fruits per plant, whereas the maximum fruit length was observed for the genotype LCA-740. The genotype Warangal Chapatta recorded highest fruit diameter, dry fruit weight and number of seeds per fruit, whereas the genotype LCA-625 recorded highest dry fruit yield per plant.
