abstract almond is an important nut tree which is cultivated in many mediterranean countries. this study was carried out to study some vegetative and reproductive traits as well as qualitative and quantitative characteristics and their correlation in some self-compatible and self-incompatible genotypes obtained from crossing between touno (male parent) and shahrood 12 (female parent). quantitat...

Induction of milk\disease in 50% of Japanese beetle (Popillia ;apmlica) !aIT,\(' 1)\· feeding requires about IQ1l spores of Bacilllls popilliae per gram of soil. The infectious process occurs in four phases: (1) An initial incubation phase of about :2 da~'s during which there is no evidence of infection in the hemoh-mph. (2) ,-\ \'egetative phase of poJiferation in the hemolymph which lasts unt...

date palm tree reaction to fertilizer is very slow, due to the trunk nutrients. this fact leads to farmer unwillingness to feed the trees. however, balance fertilizing improves vegetative growth and reduce the period for flowering. this study aimed to assess the effects of manure, chemical and organic sulfur on vegetative characteristics of ‘piarom’ date palm offshoot in a randomized complete b...

Translationally controlled tumor protein (TCTP) is a highly conserved and ubiquitously expressed protein present in all eukaryotes. Cellular functions of TCTP include growth promoting, allergic response and responses to various cellular stresses, but the functions in filamentous fungi have not been reported. In this report, we characterized an Aspergillus nidulans TCTP (TcpA) with high similari...

Two Þeld experiments were conducted in 1995Ð1996 to determine if there are common photosynthetic and vegetative growth responses among genotypes of maize, Zea mays L., to larval western corn rootworm, Diabrotica virgifera virgifera LeConte injury. SpeciÞc variables measured from rootworm infested and noninfested plants were midday leaf photosynthetic rate, plant growth stage, and plant height d...

Teopod 2 (Tp2) is a semidominant mutation of maize that prolongs the expression of juvenile vegetative traits, increases the total number of leaves produced by the shoot, and transforms reproductive structures into vegetative ones. Here, we show that Tp2 prolongs the duration of vegetative growth without prolonging the overall duration of shoot growth. Mutant shoots produce leaves at the same r...

In a plant, the progression from vegetative growth to reproductive growth is called the floral transition. Over the past several decades, the floral transition has been shown to be determined not by a single gene but by a complicated gene network. This important biological process, however, has not been investigated at a genome-wide network level. We collected Arabidopsis (Arabidopsis thaliana)...

Stachys L. one of the biggest genus of the Lamiaceae family comprises about 200-300 species.  In this research, aerial parts essential oil composition and content of Stachys lavandulifolia Vahl (Lamiaceae)at different stages (vegetative, full flowering and initial fruiting stages) is reported. The oils obtained by water distillation method (Clevenger apparatus) and analyzed by GC and GC/MS. The...
