The results of qualitative phytochemical analysis showed the presence of several bioactive compounds viz., polyphenols, flavonoids, terpenoids, steroids, glycosides and alkaloids. Quantitative estimation of glucosinolates in terms of potassium thiocyanate equivalence/5 mg of extract revealed that the cabbage has highest content of glucosinolate (122.6 μg) followed by cauliflower (109 μg), kohlrabi (101.6 μg) and radish (60.2 μg). The four cruciferous vegetables registered notable cell proliferation inhibition at different concentrations (50, 100, 200, 400 and 800 μg/mL) in a dose dependent manner against three different cell lines. The results of antiproliferative activity was expressed in terms of IC50.

Barhee. Seventeen treatment combinations were made to study the survival, contamination and mortality percentage of in vitro grown date palm explants. The laboratory experiment was laid out on completely randomized design with three replicates in each treatment. The findings revealed that application of 5 mg L-1 silver nanoparticles alone and in combination with 80% sodium hypochlorite and 0.2% mercuric chloride statistically behaved alike. However, maximum survival of explants (88.89%) and zero percent mortality was observed when 5 mg L-1 silver nanoparticles was used alone. Higher concentrations of silver nanoparticles (10 and 20 mg L-1) when combined with sodium hypochlorite and mercuric chloride had a detrimental effect and caused highest explant mortality. Application of sodium hypochlorite and mercuric chloride showed 33.33% contamination and 11.11% explant mortality.

The experiment were conducted in a factorial arrangement based completely randomized design with five replicates. Various morphological (plant height, shoot biomass, root biomass, root length, leaf area, flower number, diameter) and biochemical attributes (chlorophyll, carotenoids, flower anthocyanin content, P content, total sugar, starch and protein content) were measured after 60 days. The results indicated a variation in growth response of Z. elegans with different treatments. AMF alone or in combination helped in increasing the different parameters of Z. elegans. The combination of G+A showed maximum increase of growth parameters followed by G+T and G+A+P. Consortium inoculation of bioinoculants plants with G+A+T+P treatment proved to be the best treatment for total proteins and total chlorophyll content while flower anthocyanin content was best in G+A treatment. AMF promotes higher AM colonization and spore number enhancing nutrient acquisition especially phosphorus, producing plant growth hormones resulting in an improvement of rhizospheric condition of soil, altering the physiological and biochemical properties of Z. elegans.

Production of Scotch bonnet peppers in greenhouses with insect-excluding screens covering the sideand end-walls would render the plants virus-free and would extend the harvest season which is limited by damaging rainfall during the wet season. We found in Delaware, USA (39.68° N) that fruit yields from greenhouse-grown plants were far greater than those expected from field-grown plants in Jamaica. Greater fruit number and weight of marketable fruits per plant were achieved from nonpruned plants compared to those from plants pruned to either of two Dutch V systems [plants pruned to two main stems and subsequent laterals pruned to one (V1) or to three (V3) nodes]. These differences were less pronounced when fruit yield was expressed on a per m-2 basis since pruned plants were closer together (1.8 plans m-2) than non-pruned plants (1.1 plants m-2).
