Fourty-two kinds of benzaldehyde O-alkyloximes derived from benzaldehydes were prepared and their biological activities were investigated. Introduction of a fluorine or bromine atom to the benzene ring of the oximes enhanced their phytotoxic activity. The O-alkyloximes with a fluorine atom at the 3 or 4 position of the benzene ring were more active than the other oximes in the GA3-induced α-amy...

Chromium is one of the most toxic heavy metals which reduces the growth of plants at relatively low concentrations, whereas IAA, kinetin, GA3 and 24-epibrassinolide (24-epiBr) are well known plant growth regulators (PGRs) which enhance the growth of plants. The present study was undertaken to determine the effect of binary combinations of Cr(VI) and PGRs on Spirodela polyrrhiza (L.) Schleiden, ...

The influence of pre-sowing treatments using hydropriming, osmopriming and halopriming in laboratory and/or nursery tests on seedling emergence, seedling weight and plant growth of endive and chicory was examined. Halopriming (KNO3) or growth regulators (gibberelic acid; GA3) improved the rate of germination of endive and chicory and reduced the mean germination time needed. 30 min pre-sowing t...

A novel combination of plant growth regulators comprising indole-3-butyric acid (IBA), 6-benzylaminopurine (BA) and gibberellic acid (GA3) in Murashige and Skoog basal medium has been formulated for in vitro induction of both shoot and root in one culture using cotyledonary node explants of guar, (Cyamopsis tetragonoloba). Highest percentages of shoot (92%) and root (80%) induction were obtaine...

This study analyzed the potential of producing Melissa officinalis L. using stem cuttings. Four different hormones (IAA, IBA, NAA, and GA3) were applied to the cuttings, with and without buds, in two doses (1000 mg/L and 5000 mg/L), and after 60 days, 10 morphological characteristics of newly generated plants were detected, and a statistical analysis was carried out. The results of the study sh...

Storage proteins in cotyledons of legume plants are degraded by proteinases after germination. We examined whether abscisic acid (ABA), gibberellin (GA) and brassinosteroid (BR) are involved in the expression of cysteine proteinases in cotyledons of common bean seeds with RNA blotting using cDNAs for five papain-like proteinases, EP-C1, CP1, CP2, CP3, CP4 and two legumain-like proteinases, LLP1...

Bu çalışma, hıyar fidelerine boy kontrolünü sağlamak amacıyla uygulanan prohexadione-calcium’un (Pro-Ca) durdurucu etkisinin, gibberellik asit (GA3) uygulamalarıyla ne şekilde etkileneceğinin belirlenmesi yapılmıştır. Hıyar ilk gerçek yapraklarının görüldüğü aşamada yapraktan sprey şeklinde Pro-Ca’nın dört dozu (0, 50, 100 ve 200 ppm) dikimden hemen önce ise GA3’ün üç 50 uygulanmıştır. Deneme 4...

To explain the relationship between rhizosphere fungi diversity and community composition of alfalfa under drought stress endogenous hormones in alfalfa, we used sand culture to investigate performance Medicago sativa ‘Qingshui’ (or QS), M. ‘Longdong’ LD), varia ‘Gongnong No. 4’ GN) with contrasting different degrees tolerance. After 7 days treatment, underwent significant changes, found Ascomy...

the effect of gibberellic acid (ga3) on jerusalem cherry (solanum pseudocapsicum l.) was evaluated at pot cultivation conditions. this study was performed in factorial test based on complete random design plan and 4 repeats with 12 treatments. the main factor was included spraying, drip and spraying + drip. secondary factor was included concentrations of ga3 at 0, 100, 200 and 400 mg.l-1 levels...

One strategy to increase shallot productivity is use fertilizers and growth regulators. The aim of the study was determine response vegetative generative shallots local Eban cultivars through application gibberellins P in middle plains North Central Timor District. This used a factorial randomized block design (RBD). first factor (GA3), consisting three treatments, namely without GA3 (control),...
