Variations among some Nigerian Cucurbita landraces
The diversity among some Nigerian accessions of Cucurbita species was investigated using 19 quantitative and 14 qualitative characters. The result showed that the accessions evaluated differed significantly (p < 0.05) in most of the quantitative characters evaluated. The clustering based on quantitative character, grouped the various accessions into two clusters. However, clustering based on the...

Effect of IBA and age of cuttings on rooting behaviour of Jatropha Curcas L. in different seasons in western Himalaya, India
Present study deals with the effect of different concentrations of IBA on rooting behaviour of Jatropha curcas L. stem cuttings in different seasons. The study was carried out in Western Himalayan region in Uttarakhand, India during 2005-2006 in spring, monsoon and winter season. The juvenile and mature cuttings of J. curcaswere treated with different concentration of IBA (0, 500,...

Kinetics of drumstick leaves (Moringa oleifera) during convective drying
Drying characteristics of drumstick leaves (Moringa oleifera) were investigated in a convective type dryer for a temperature range 50 to 80ËšC at constant air velocity, 0.5 m/s. Results indicated that drying took place in the falling rate period. The sample dried at 60ËšC was found better in color as compared to the samples obtained at 50, 70 and 80ËšC. The chroma of the samples, dried in between 50 to 80ËšC...

Study of influence of temperature regimes on germination characteristics and seed reserves mobilization in wheat
In a laboratory, experiment germination characteristics and seed reserves mobilization of wheat cultivars were evaluated at three temperature regimes (16, 26 and 36°C). Four heat tolerant cultivars (Gourab, Sourav, Kanchan and Shatabdi) and two heat sensitive cultivars (Sonora and Kalyansona) were used as study materials. Germination characteristics expressed as rate of germination, coefficient of...

Slow growth conservation and molecular characterization of Deutzia scabra Thunb.
Possibility of long-term storage in vitro of Deutzia scabra Thunb. shoots and their genetic stability were evaluated. The effect of mannitol concentrations (20 and 40 g/L), presence and absence of activated charcoal (AC) and temperature (24 or 4°C) in MS medium were studied in respect to survival percentage, number, length, leaves number of axillary shoots...

Pharmacological studies of Passiflora sp. and their bioactive compounds
Human infections particularly those involving microorganisms that is, bacteria, fungi, viruses, nematodes, can cause serious infections in tropical and subtropical countries of the world. In recent years, multiple drug resistance in human pathogenic microorganisms has been developed due to indiscriminate use of commercial anti-microbial drugs commonly used in the treatment of such diseases. Plants have been...
