The paper aimed to study the influence of naphthalene acetic acid (NAA) and ethephon on total phenols, flavonoids and tannins as a function of seasonality in Echinodorus grandiflorus plants. The experiment used adventitious plantlets from the flower stem with 4 to 5 leaves, planted in 10-liter pots. The leaf spray treatments applied were: control, NAA 100 mg L -1 , and ethephon 100 mg L -1 . Tr...

Biennial bearing of apple trees can be overcome either by the use of a blossom chemical thinner or by early application of a postbloom thinner. Carbaryl (Sevin) is a postbloom fruit-thinning chemical with an effective thinning period of 4 to 5 weeks after bloom. Sevin was compared in 1992 and 1993 with NAA as an early petal-fall spray. Sevin treatments reduced fruit set to one fruit per cluster...

Date palm(Phoenix dactylifera)is commercially propagated through offshoots. Alongwith thisrooted offshootthe tree also produces aerial offshoots,which arerootlessand die after plantation. In this study attempts have been made to evaluate the effect of auxins on root initiation offshootsof date palm cv. Hillawi.Therefore, an experiment was conducted theeffect IAA (500 ppm), NAA(500 alone and in ...

Ecklonia maxima and the commercial biostimulants produced from it contain various plant growth regulators that are responsible for stimulation recorded in many crops. Auxins one of major contained E. extracts. The aim this research was to evaluate growth-promoting effect a seaweed extract on lettuce tomato transplant production under nursery conditions, compare with an equal concentration synth...

background and objectives: grape has high nutritional value and it is an economically important horticultural plant in the world. iran has seventh producer grape rank in the world. today tissue culture is one of technique which can be used in grape propagation and breeding. material and method: in order to optimization of callus induction and micropropagation of grape in vitro condition, this i...

Parthenocissus plant is one of the most attractive outdoor deciduous vines; provides deep green cover to most any object, rapidly climbing by means of tendrils and adhesive disks, can be espaliered against a wall and provides great visual appeal during winter when the leaves have fallen. Rooting the cutting of this plant is difficult without using a rooting hormone, so the present research proj...

This study represents the first paper of the effects of growth regulators on the physiochemical and phytochemical properties of the wax apple fruit, a widely cultivated fruit tree in southeast Asia. Net photosynthesis, sucrose phosphate synthase (SPS) activity, peel color, fruit firmness, juice content, pH value, total soluble solids (TSSs), and the sugar acid ratio were all significantly incre...

Leaf area index (LAI), leaf area duration (LAD), crop growth rate (CGR), net assimilation rate (NAR) and above ground dry matter accumulation (AGDM) of a cultivar of chickpea (Cicer arietenum) were studied with the application of potassium naphthenate (KNap) and naphthalene acetic acid (NAA) as foliar spray in 2001-2002. The growth regulators had greater influence on plants which showed compara...

The mulberry tree (Morus alba) is a perennial and fast-growing distributed worldwide under different climatic conditions. Most of the world’s silk production (>90%) facilitated by feeding silkworm larvae on leaves alba L.) varieties. Therefore, exploration protocol for improving propagation efficiency increasing reproductive capacity M. varieties could be great significance. This study aimed...

Sugarcane problems in germination will effect on growth and the yield that is not optimal. The solution obtained from these plant regulators soaking storage time bud sett seedling before planting. This study used a factorial experimental method with first factor being consisting of 3 levels, namely 0 days (control), 1 day, 2 days. second was PGR which consisted control (without soaking), NAA + ...
