Nitric oxide: A ubiquitous signaling molecule with diverse role in plants

Nitric oxide (NO) is a gaseous di-atomic radical, readily diffusible through biological membranes and readily soluble in water is having a wide array of physiological, biochemical and molecular events in animals, plants and microbes. NO reacts directly with metal complexes and other radicals and indirectly as a reactive nitrogen oxide species with DNA, proteins, and lipids. In animals, NO is well established as a...

Diversity of landraces, agricultural practises and traditional uses of watermelon (Citrullus lanatus) in Mozambique

A survey was carried out in three provinces of Mozambique with different agroecological conditions to document traditional knowledge related to cultivation and use of indigenous watermelons, and to describe the diversity of landraces within the country. Semi-structured interviews were used to collect information at the household level or in farmers’ watermelon fields. Watermelons were intercropped with the main...

Influence of lanthanum on biochemical constituents and peroxidase activity of cowpea (Vigna unguiculata (L.) Walp.)

The effect of various concentrations (0.1, 0.5, 2.5, 12.5 and 62.5 µg g-1) of Lanthanum as Lanthanum nitrate added to soil was studied on the content of foliar chlorophyll (Chl. ‘a’, Chl. ‘b’, Total chl.), soluble leaf protein, total phenol contents and peroxidase activity of cowpea [Vigna unguiculata (L.) Walp.]. Lower applications (0.1 to 2.5 µg g-1) of La resulted in...

Growth response of Anogeissus leiocarpa coppices to prescribed fire and weeding after plantation harvesting in the Sudanian zone of Mali, West Africa

A nineteen-year-old plantation of Anogeissus leiocarpa in Zangasso forest was coppiced in order to study the sprouting and shoot growth according to cutting intensity and management mode. Two intensities of cutting (clear cutting and selective cutting) and two management modes (weeding and early fire) were experimented. Clear cutting was found better than selective cutting regarding the percentage of stump...

Evaluation of the fruit-drop of Myrciaria dubia (H.B.K.) Mc Vaugh, camu-camu, in the “five River Basins” collection of the San Miguel experimental research station - IIAP, Loreto, Peru

This study presents preliminary findings regarding the factors that cause fruit-drop in a collection of camu-camu originating from natural stands in five different river systems in Loreto, Peru. We evaluate the percentage of fruits attacked by insect pests, the retention of flowers and fruit according to branch diameter, and the influence of rainfall and temperature on fruit-drop. With respect to factors related to...

Multivariate assessment of the agromorphological variability and yield components among sweet potato (Ipomoea batatas (L.) Lam) landraces

Understanding the nature and magnitude of variability existing among sweetpotato genetic materials for important traits is vital for the effective utilization of such materials for breeding purposes. Eighteen landraces from diverse origins, plus three released cultivars as checks, were evaluated in two contrasting locations, using nine agronomic and eight morphological traits of the crop, to estimate the nature and...

Studies on the asthma coughs plant Crinum jagus L. (Amaryllidaceae) in Nigeria

Some morphological and anatomical features of Crinum jagus L. were investigated and described. The student t-tests conducted indicated highly significant differences (P = 0.05) in the mean epidermal cell density, mean stomatal density, mean stomatal length and mean guard cell area between the adaxial and abaxial leaf surfaces. However, the investigation ‘between plants’ variations did not indicate...

Chemical composition and antifungal activity of volatile components from woody terminal branches and roots of Tetraclinis articulate (Vahl.) Masters growing in Tunisia

The chemical composition of the volatile fractions obtained from distilled woody terminal branches and roots of Tetraclinis articulata (Vahl.) Masters was identified by Gas Chromatography- Flame ionization detectors (GC-FID) and Gas Chromatography-Coupled with Mass Spectrometry (GC-MS). Twenty compounds represented 83.7% of the essential oil from woody terminal branches and 29.2% from the...

Investigations on the phytochemical activities and wound healing properties of Adhatoda vasica leave in Swiss albino mice

Adhatoda vasica has been used in many ayurvedic formulations. In order to evaluate the wound healing activity of A. vasica, five different solvent extracts were prepared from the leaves of the plant. Methanol, ethanol, ethyl acetate, chloroform and hexane were used for the extraction of the active ingredients. Excision wound model on Swiss albino mice was used to assess the wound healing activity of the...
