A study was conducted to determine how shade (0%, 40%, 80%) reduces high light intensity and temperature to optimize growth of ranunculus (Ranunculus asiaticus L.) under high altitude tropical conditions. The study was set up in a split plot design, replicated three times and repeated once. Ranunculus tuberous roots were preconditioned at 30C, 20C, 10C or 2C for two weeks and thereafter grown u...

abstract genetic diversity of german chamomile (matricaria chamomilla l.) populations in iran was evaluated using morphological, agronomical and phonological characteristics and compared with three cultivars from germany, hungary and iran. in this experiment, statistical design of rcbd with three replications was used, sixteen quantitative traits were measured such as yield, flower number per p...

Combining ability in forage sorghum [Sorghum bicolor (L.) Moench] was not as much investigated as in grain sorghum. In the present study, 4 local stocks (Testers) and 7 exotic stocks in A3 cytoplasm were crossed in line x tester fashion to investigate combining ability in forage sorghum. The hybrids and their parents were evaluated across two years (2002 2003) and at two locations in Khartoum S...

BACKGROUND: Biofertilizers, like amino acids, are used to reduce drought stress damage to plants and improve physiological factors, thereby increasing plant yield in arid and semi-arid regions. Seaweed extract has a beneficial effect on plant growth due to its growth hormones and elements such as iron, copper, zinc, cobalt, molybdenum, manganese and nickel, vitamins and amino a...

gerbera (gerbereajamesonii) cut flower has magnificent economical value in international cut flower industry. due to sensitivityto ethylene and to gray mold, it has a short postharvest life. in this research, the effects of pulsing treatments with salicylic acid (100 and 200 mg/l) and methyl jasmonate (25 and 50 mg/l) for 24h on quality and vase-life of gerbera cut flower were assessed. distill...

the present study was conducted to investigate the yield and some morphological characteristics of echinacea purpurea. the experiment was conducted in research farm of the ramin agriculture and natural resources university of khuzestan during 2013- 2014. the experiment was performed as a split plot factorial based on a randomized complete block design (rcbd) with four replications. the foliar a...

greenhouse and laboratory studies were conducted to examine the allelopathic effects of water extracts of pigweed (amaranthus retroflexu l.) leaf, stem, root and flower at different growth stages on canola seed germination and seedling growth. water extracts of leaf, stem, root and flower as individually, binary, ternary and quadri mixtures at 0, 50 and 100% concentrations were made and their e...
