AIM This study was designed to investigate the bioactive compounds in Costus afer Ker Gawl, an indigenous African medicinal plant whose leaf and stem extracts are used in the treatment of chronic inflammatory diseases, especially rheumatism and arthritis. MATERIALS AND METHODS The bioactive compounds present in the n-butanol fractions of C. afer leaf and stem were identified using qualitative...

Very little is known about sugarcane gene sequences. In this study, the aim is to identify sugarcane genes expressed in the leaf roll and the mature stem. Random DNA sequencing of cDNA clones allows the identification of genes and the development of Expressed Sequence Tags (ESTs). A total of 250 clones randomly selected from a leaf roll cDNA library and 112 from a mature stem library have been ...

background: achillea tenuifolia lam. (compositae) with small yellow flowers and several times pinnately divided leaves in worm shape is known for many years in the folk medicine. it has been used to reduce sweating and to stop bleeding. it helps regulation of the menstrual cycle and reduces heavy bleeding and pain. materials and methods: plant material (flower, leaf and stem) was collected in k...

the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...

Three growth trials and one digestion trial were conducted to compare the effect of dietary fat sources and combinations on starter pig performance, nutrient digestibility and intestinal morphology. Growth trials 1 and 2, utilizing a total of 324 weanling pigs (21 +/- 3 d), were conducted to determine the influence of addition of soybean oil, coconut oil, choice white grease, 50% soybean oil: 5...

in order to evaluate the allelopathic potential of sunflower (helianthus annus l.) organs on germination and growth of dodder (cuscuta compestris l.), series studies were conducted in three separate experiments; as factorial based on completely randomized design (crd) with three replications for each experiments. first experiment was conducted in petri dishes and consisted of sunflower organs a...

Effect of Nutrient Source Type and Planting Media on Growth Yield Quality Microgreen Broccoli (Brassica oleracea var. italica Planck). The use types nutrient sources planting media is the most important thing in cultivation microgreen broccoli which functions to support growth development so as get good yields. purpose this study was obtain best source growing increasing yield. designed factori...

ABSTRACT The use of coconut coir dust is a low-cost cultivation practice. Thus, this study aimed to determine the effect proportion on foliar secondary metabolite biosynthesis and growth Passiflora alata Curtis (sweet passion fruit). This species possess pharmaceutical relevance organic-based substrates may promote production bioactive compounds in phytomass. An experiment greenhouse was set up...

Fifty coconut palms exhibiting early symptoms of lethal yellowing were selected for treatment with oxytetracycline-HCl, tetracyclineHC1, streptomycin nitrate, potassium penicillin-G, or griseofulyin. Two grams of antibiotic in 0.2 or 1.0 liters of water were pressure injected into the trunk of each tree except for the griseofulvin treatments which were applied as a paste into holes bored in the...

1. The experiments show that the mass of air roots formed in a stem increases with the mass of the leaf attached to the stem, though it has not been possible to establish an exact mathematical relation between the two masses, owing to unavoidable sources of error. 2. Darkened leaves do not increase the mass of roots formed. 3. In stems suspended horizontally air roots appear on the lower side o...
