Pressure-volume curves were determined for black spruce (Picea mariana (Mill.) BSP) trees from four full-sib families. During the first two years, trees were measured from a plantation on a dry site. In the third year, trees were sampled from the dry site and a wet site. Diurnal measurements of shoot water potential allowed in situ shoot turgor to be estimated in addition to standard water rela...

Using plants for the remediation of soils contaminated with heavy metals is an economical, cheap, and effective strategy. The goal of this research was to study the effect of sewage sludge and drought stress on the remediation of cadmium in soil, root uptake by corn plant. This study was carried out on corn in factorial design experiment based on completely randomized design with three replicat...

Five strains of Trichoderma with known biocontrol activities were assessed for their effect upon pea growth and their antagonistic activity against large Pythium ultimum inocula. The effect of Trichoderma inocula upon the indigenous soil microflora and soil enzyme activities in the presence and absence of Pythium is assessed. In the absence of Pythium, Trichoderma strain N47 significantly incre...

allelopathic relationship between plant associations, could be applied in non-chemical ‎weed management, however, those allelochemicals should not have adverse effects on arable ‎crops. in order to evaluate allelopatic effects of barley (hordeum vulgare) on ‎germination & growth characteristics of lentil (lens esculenta), two experiments were ‎conducted based on compactly randomized design (crd...

to study the effect of salinity and organic matter on chemical composition and root morphology of pistachio cv. badami, budded on seedling root stocks, a greenhouse experiment was conducted as a factorial based on a completely randomized design with three replications. treatments consisted of four salinity (zero, 800, 1600 and 2400 mg nacl kg-1 soil) and three organic matter (zero, two and four...

Quality of seeds of three cultivars (IPSA Seem-2, BU Seem-3 and IPSA Seem5) of lablab bean (Lablab purpureus L. Sweet) collected from crops planted in three different dates (15 May, 15 July, and 15 September 2003) was assessed in respect of different parameters. The maximum percentage of seeds of cv. IPSA Seem-2 was germinated (95.67) whereas, BU Seem-3 had the maximum electrical conductivity (...

Lipids in liver wet and dry matter, liver moist and dry matter and their relationships were investigated based on species, sex and age in cows, buffaloes, sheep and goats. Mean percentage of lipids in liver wet and dry matter and liver dry matter in cows were 3.60%, 1.10%, 29.70%, and for buffaloes were 5.30%, 1.55%, 29.20%, sheep 3.00%, 0.83%, 27.90%, and goats 2.910%, 1.55% and 28.40%, respec...

The levels of endogenous gibberellin A(1) (GA(1)), GA(3), GA(4), GA(9), and a cellulase hydrolyzable GA(9) conjugate in needles and shoot stems of mature grafts of Sitka spruce (Picea sitchensis [Bong.] Carr.) grown under environmental conditions that were either inductive, hot, and dry, or noninductive, cool, and wet, for flowering, were estimated by combined gas chromatography-mass spectromet...

ABSTRACT: The peach palm (Bactrisgasipaes) is an important alternative for heart-of-palm extraction, showing precocity, rusticity and high tillering. seeds of this species are considered recalcitrant making storage long periods production seedlings difficulty. This identified a combination moisture content temperature during longer seed longevity. Seeds with 35% 45% (wet basis - wb) were at 20 ...
