Variation of quercetin content in different tissues of Welsh onion (Allium fistulosum L.)

  Due to its proposed potential role in reducing risk of cardiovascular disease and some forms of cancer, flavonol level in plants is an important trait. In this study, nine Welsh onion cultivars were grown in 2006 in Jinan, and six cultivars were grown in 2007 in Qingdao to study the distribution of quercetin (a flavonol) among different tissues of the Welsh onion. After harvest,...

Determination and evaluation of superior self-compatible almond genotypes resulting from crosses between “Touno” and “Ferragnes” in Iran

  Self-incompatibility is one of the most considerable difficulties in almond production, which reducing fruit set dramatically and making orchard management difficult. Therefore, breeding almond to produce self-compatible genotypes is very important. The purpose of this investigation was determination and evaluation of self- compatible and late flowering cultivars with good kernel characteristics in 38 almond...

Effects of irrigation frequency regimes on morphological and physiological characteristics of six sedum species

  Nowadays, green space expansion is faced with some limitations such as water and budget deficiency. There are some recommendations about limiting usage of turfgrass and replacing it with ground cover plants in urban green space. These recommendations are in a form of a program, which is called Xeriscaping. This study has been conducted to investigate the adaptability of new ground cover plants in Mashhad...

Assessment of weed management strategies and intercrop combinations on cassava yield in the middle belt of Nigeria

This study assessed the determinants of weed management strategies on yield of cassava in Kogi State, Nigeria using the ordinary least square regression analysis. A multi-stage random sampling technique was used to select 450 cassava farmers in the state in 2009. The result showed that there was a significant difference in the yield of cassava between plots applied with herbicides  and plots without...

The photosynthetic physiological properties of Illicium lanceolatum plants growing under different light intensity conditions

  In this study, the photosynthetic properties and CO2 conductance of four-year old plants of Illicium lanceolatum were measured under three different light conditions (full light, half shadow and shadow) treatments. The results show that during the peak growth season, compared to those under full light, plants growing under half shadow light condition had the highest net...

Induction of systemic resistance in soybean plants against Fusarium wilt disease by seed treatment with benzothiadiazole and humic acid

  The ability of benzothiadiazole (BTH), humic acid (HA) and their combination when used in seed soaking to induce systemic resistance against a pathogenic strain of Fusarium oxysporum was examined in four soybean cultivars under greenhouse conditions. Both inducers and their combination were able to protect soybean plants against damping-off and wilt diseases compared with check treatment. These...

Soil physicochemical properties and vegetation pattern in an arid environment affected by a salt diaper

  Soil degradation, most notably caused by salinization and water-logging, creates formidable problems in arid and semi-arid environments. Advancing our knowledge of salt-affected soils is a prerequisite for understanding how salinization affects environmental concerns, such as soil erosion, nutrient leaching, and lack of vegetation cover. Therefore this study investigated the impact of salt diapirs on soil...
