In vitro morphogenic response of mature seed embryo-derived callus cultures Chonemorpha fragrans was studied using solid and liquid Murashige Skoog medium amended with cytokinins or their combinations naphthalene acetic acid at 0.5 mg L-1. The plant growth regulators (PGRs) combination concentrations tested could not stimulate organogenesis after three subcultivations the on same PGRs-amended w...

• j ermudagrass is a popular turfgrass used on athletic fields • due to its aggressive summer growth habit, fine leaf texhue, and dark green color. However, if mowed infre• quently, excessive scalping and dipping production combine to decrease its aesthetic quality. Plant growth fl:'gulalors (PGRs) were introduced into the turf industry in the 1950's and since have been used in part to reduce m...

Gladiolus is an important marketable cut flower, especially valued for use in floral arrangements. We assessed the effects of two different methods of application (foliar spray and drench) and various concentrations of gibberellic acid (GA3), salicylic acid (SA), mival (MI) and krizatcin (KR) on vegetative and reproductive features of Gladiolus hybridus. The experiment was planned in a factoria...

individual grain weight of wheat kernels differs with their positions on a spike. cultivation practices (such as fertilizer nitrogen and plant growth regulators application) can be used to improve weight of basal and distal kernels. for this purpose, two experiments based on randomized complete block design were carried out with three replications. the aim of this research was to study the mech...

Merremia emarginata plants were treated with different plant growth regulators (PGRs): naphthyl acetic acid (NAA), phenyl acetic acid (PAA) and gibberellic acid (GA 3). To determine the role of wall stiffening enzymes in internode elongation, IAA oxidase and peroxidase in the presence of different hydrogen donors like caffeic acid, chlorogenic acid and guaiacol were assayed. The levels of total...

Pistachio is one of the economically important horticultural crops in Iran. The main pistachio-producing areas in Iran are located at the edge of the desert and are affected by soil and water salinity. Water and nutrient uptake by the root decreases under saline conditions. In this study, the effects of foliar growth regulators applied at different times on the nutrient uptake and leaf nutrient...

This study aimed to assess the effects of plant growth regulators (PGRs) on stock production mojave sage ( Salvia pachyphylla ) and ‘Avalanche’ cape daisy Osteospermum hybrid) that received foliar sprays following three PGRs: 200 400 ppm ethephon; 250 500 benzyladenine; 50 100 gibberellic acid 4 7 (GA 4+7 plus benzyladenine. Vegetative [height width index (GI)], number vegetative cuttings, fres...

In this study, the water supply in soil for wheat mother donor plants was controlled, leading to drought stress conditions, and the relative soil water content (RSWC) was measured in different soil depths. The immature embryos of common wheat (Triticum aestivum L.) 13 days post anthesis (DPA) were used to test regeneration capacity. The accumulation of the plant growth regulators (PGRs) includi...

Plant growth regulators (PGRs) play a key role in regulating physiological and morphological development of plant species. Application of these PGRs can improve preand post-harvest quality and quantity of ornamental flowers and lessen the harmful effects of injury incurred at harvesting time. The objective of this study was to determine the appropriate spraying solution for improving preand pos...
