The crop will be free from the control of apical dominance and axillary buds develop into branches after topping. However, there are relatively few studies on this subject soybean. In order to further improve soybean grain yield, unbranched type high-yield variety was used as test material, effects topping at first trifoliate stage plant growth, dry matter accumulation, yield components five pl...

The aroma constituents of Chrysanthemum indicum L. were separated by the hydro distillation extraction method using a Clevenger-type apparatus, and were analyzed by gas chromatography-mass spectrometry (GC/MS). The yield of Chrysanthemum indicum L. flower oil was 2.0% (w/w) and the color was light golden yellow. Sixty-three volatile flavor components, which make up 89.28% of the total aroma com...

The efficiency of high pressure extraction of lutein diesters from marigold (Tagetes erecta) flower petals has been investigated. The solvents used for extraction were supercritical carbon dioxide and liquid propane. Operating parameters were 300 bar and 40, 60 and 80 °C for CO2 and 100, 150, 200 bar and 40 and 60 °C for propane, respectively. The influence of process parameters on the total yi...

The hormone levels of auxin and gibberellin were studied in monoecious cucumber plants treated with growth regulators e.g. 2-chloroethylphosphonic acid (ethrel), gibberellic acid (GA3) and maleic hydrazide (MH). The studies were conducted at Vegetable Crops Research Programme, National Agricultural Research Centre Islamabad, Pakistan during 2003 and 2004. The greatest increase in female flower ...
