The objective of this study was to evaluate the agronomic characteristics of sugarcane as a function of the no-tillage system (NTS) compared to the conventional one (CS) with, and without, manuring. The experimental design was completely randomized, using four repetitions, in a factorial scheme 4 x 2. The treatments were: sugarcane NTS on sunnhemp (Crotalaria juncea); sugarcane NTS on jack bean...

Answer 2 PPD is caused by at least four different plant families: Apiaceae (formerly Umbelliferae), Rutaceae, Moraceae and Leguminosae.1–3 The Apiaceae family, the most common plant family implicated, has a distinctive floral umbel that makes them easy to recognise.3 Parsley, parsnips, celery and carrots are examples from this group. The Rutaceae family includes Citrus and Ruta species and is t...

Potentially nodulating Leguminosae species had high density and biomass in young stands of forests Northeast Brazil, except a dry forest on low-fertility soil. species, especially potentially ones, appear to be important components tropical secondary forests, although information is still scarce concerning their contributions richness under different environmental conditions. To evaluate the co...

abstract background: alkaloids from senna alata leaves implicated as the active constituents of abortifacient are yet to be investigated for their effects on the normal functioning of the maternal liver and kidney. therefore, the effects of crude alkaloids on some biochemical indices of kidney and liver damage were investigated in pregnant rats. methods: pregnant rats were randomized into 4 gro...

Endosperms from seeds of different subfamilies of Leguminosae were submitted to sequential aqueous and alkaline aqueous extractions. The extractions from species belonging to the Mimosoideae and Faboideae subfamilies yielded galactomannans with constant Man:Gal ratios, whereas the extractions from Caesalpinioideae seeds gave rise to galactomannans with increasing values of the Man:Gal ratio. Th...

Leguminosae Juss. é a terceira família de angiospermas com maior diversidade em número espécies, sendo representada por 770 gêneros e cerca 20.000 espécies seis subfamílias (Lewis et al., 2005; LPWG, 2017).

Many species of Acacia have been tested by Mr. E. P. White for the presence of alkaloids in plants grown in New Zealand. He identified tryptamine, phenylethylamine, and N-methylphenylethylamine. Acacia kettlewelliae Maiden was found by White1 to oontain about 1.5% base in its leaves and stems, 92% of which was 2-phenylethylamine. A sample of leaves collected at Creswick, Victoria, gave 0.9% bas...

numerous studies have been focused on natural anticarcinogenic agents. many antioxidants have been identified as anticarcinogens. antimutagens have also been proposed as cancer chemopreventive agents. the use of natural products as anticancer has a long history that began with traditional medicine. the aim of this study was to evaluate cytotoxicity and antioxidant activity of twenty-three plant...
