An efficient protocol for in vitro flowering of Spilanthes acmella Murr., a medicinally valuable plant, has been developed. Multiple shoot formation of up to 4 shoots was obtained on Murashige and Skoog (MS) medium supplemented with BAP (1.0 mg/l). Regenerated shoots were subcultured cultured on MS medium containing various concentrations of BAP alone or in combination with IAA. Presence of BAP...

Creating a forcing schedule A forcing schedule can be drawn up by using the previously listed cold periods. For example a forcing operation wants to have marketable pot hyacinths with flower clusters easily visible between the leaves on 7 December. If it takes one week to green up and pre-force the plants in the greenhouse, and if the cold period for that cultivar is 10 weeks, the bulbs will ha...

This study was carried out to evaluate the effects of different plant growth regulators on ornamental sunflower plant. The seedlings belonging Helianthus annuus L. cv. Sunsantion F1 were planted in plastic pots (2 L) containing peat:perlite (1:1, v/v) medium at four true leaf stage. Spray treatments aminoethoxyvinil glycine (AVG; 250 and 500 ppm), promalin (5 10 thidiazuron (TDZ; 5-10 µM), ethe...

Nutrient stress in Upland cotton (Gossypium hirsutum L.) depresses lint yield, particularly of late-season fruit (bolls), and may disrupt fiber development. A 2-year (1999 and 2000) study was conducted outdoors in large pots to determine individual effects of nitrogen (N) and potassium (K) stress at flowering stage on lint yield and fiber quality. Treatments were half-strength nutrient solution...

Aedes albopictus has been shown to be a vector for diseases which have been on the increase, such as dengue fever and chikungunya infection. We conducted a study of 100 homes from 2006-2009 to determine the breeding sites for Ae. albopictus mosquitoes in Calicut, Kerala, India. We found the larvae of Ae. albopictus mosquitoes most often in coconut shells and plastic waste, followed by tires, fl...

Abstract Plastic waste is increasing worldwide, contributing significantly to pollution and global warming. Our department uses at least 50 plastic water bottles daily; these can be reused manufacture other products. Recycling produces various products, including garden sets for kids, bricks, roof tiles, key holders, flowerpots. Through this project, we contribute the fight against caused by de...

Water stress is one of the main factors of severe damage and limitation of plant production in Iran. The paper reports a pot experiment conducted by using a factorial experiment based on a completely randomized design with three replications (each replication composed of four pots) to compare the physiological and biochemical characteristics of two varieties of tuberose (double- and single-flow...
