Ethiopia is the center of origin for Ethiopian mustard (Brassica carinata). The crop one oldest oil crops and farmers in highlands country grow as a leafy vegetable their gardens. However, no attempt has been made to assess association characters path analysis leaf. This study was conducted traits among yield related determine direct indirect effects traits. A total 36 genotypes were evaluated ...

This research was carried out for evaluating phenotypic diversity and traits correlation in 60 almond genotypes and cultivars in nursery conditions. After preparation land and the bitter seeds of Shahroud22 genotype as seedling rootstocks planted in the autumn 2005. After the seed germination in the spring of the next year, the results of recorded data in 3rd may of 2006 showed that the planted...

the effect of gibberellic acid (ga3) spraying on some characteristics of cyclamen flowering trend during the second flowering year was investigated. ga3 sprays were applied in concentrations of 0, 20, 30, 40, and 50 mg/l. the trial was carried out as a randomized complete design of three replications. the total flower count, flower count during the flowering peak, days from spraying to flowerin...

A new species from Iran is described and illustrated here as Kickxia iranica (Plantaginaceae). Kickxia iranica is morphologically similar to K. commutata, a species native to Mediterranean region, however it can be distinguished from the latter by leaf shape, color of corolla, habit, stem branching and length of leaf, petiole, pedicel and corolla. Notes on its distribution, ecology and phenolog...

Essentially chlorophyll-free mitochondria from photosynthetic (leaf) and non-photosynthetic tissue (petiole) were isolated from spinach (Spinacia oleracea). Leaf mitochondria were found to contain more phosphatidylcholine than phosphatidylethanolamine compared with petiole mitochondria. Galactolipids were found in small and equal amounts (5 mol of galactolipids/100 mol of galactolipids and phos...

BACKGROUND AND AIMS Complete submergence is an important stress factor for many terrestrial plants, and a limited number of species have evolved mechanisms to deal with these conditions. Rumex palustris is one such species and manages to outgrow the water, and thus restore contact with the atmosphere, through upward leaf growth (hyponasty) followed by strongly enhanced petiole elongation. These...

Field trials with Spathiphyllum wallisii Regel were conducted at the experimental farm of Faculty of Agriculture, University Azad Jiroft in 2012 growth seasons. The aim of this work is to study the effect of foliar application with benzyladenine (BA) at 0, 100, 200 and 400 mg.L-1 and gibberellic acid (GA3) at 0, 100 and 200 mg.L-1 on the vegetative grow...

When petioles of transpiring leaves are cut in the air, according to the 'Scholander assumption', the vessels cut open should fill with air as the water is drained away by tissue rehydration and/or continued transpiration. The distribution of air-filled vessels versus distance from the cut surface should match the distribution of lengths of 'open vessels', i.e. vessels cut open when the leaf is...

Petiole growth in Thlaspi arvense L. was stimulated when a basic 8 hour photoperiod (4.20 milliwatts per square centimeter) was extended with low intensity light (0.16 milliwatt per square centimeter) from incandescent lamps. The day length extension was effective only when the light contained high proportions of far red light. Exogenous gibberellin A3 (GA3) could partially substitute for the p...
