abstract in order to study the effect of planting density and branch pruning on growth, yield and quality of greenhouse muskmelon, a study has been conducted using a factorial experiment in a completely randomized design with three replications and three factors, including cultivar (galia-52 and mirella), branch pruning (1 and 2 branch per plant), and plant density (2, 2.4, 2.8 and 3.6 plants p...

Xyloglucan endotransglycosylase (XET) activity extractable from internodes of tall and dwarf varieties of pea (Pisum sativum L.) was assayed radiochemically using tamarind seed xyloglucan as donor substrate and an oligosaccharidyl-[3H]alditol as acceptor substrate. Internodes I and II showed little elongation during the period 15 to 21 d after sowing; XET activity remained relatively constant a...

Orchardgrass (Dactylis glomerata L.) is one of the essential foraging species which used as a cool-season persistent and perennial forage grass. This research was carried out during 2019 growing season in Eastern Anatolia region Turkey. The aim our to study morphologic characteristics natural assess genetic diversity collected genotypes determine best available for future breeding programs. In ...

Nitrogen uptake from various sources by plants capable of biological reduction N2 in symbiotic systems with root nodule bacteria is influenced many factors. The aim the study was to examine influence development stage and variety pea (Pisum sativum L.) cultivated years different temperature precipitation conditions on dynamics nitrogen atmosphere (Ndfa), fertilizer (Ndff), soil (Ndfs). Pre-sowi...

24-Epibrassinolide belongs to the brassinosteroid family of plant hormones, and carbenoxolone is a synthetic analogue of glycyrrhizic acid that inhibits enzymes important in steroid and prostaglandin action in animals. The e€ect of these compounds on root nodulation, root growth and shoot growth of Glycine max (L.) Merr. cv. Tracy M was examined. Epibrassinolide reduced total nodulation, plant ...

An attempt has been made to uncouple the effects of the two primary components of shade light, a reduced red to far-red (R/FR) ratio and low photosynthetically active radiation (PAR), on the elongation of the youngest internode of sunflower (Helianthus annuus) seedlings. Maximal internode growth (length and biomass) was induced by a shade light having a reduced R/FR ratio (0.85) under the low P...

The invasive species Elodea nuttallii was recorded for the fi rst time in the Croatian fl ora in 2006, in the drainage channels of Kopački rit (Baranja). After its establishment, E. nuttallii begins to spread to the eastern and northern part of the drainage channel network from 2006–2009. High water levels are responsible for the linear spreading direction of E. nuttallii, E. nuttallii and E. c...

Pseudosasa amabilis (McClure) (Poales: Gramineae) is a typical bamboo species naturally distributed in large area of south China and famous for its culm strength. Although bamboos were found to share the same development rule, the detailed internode morphology of bamboo culm was actually not fully expressed. We explored internode morphology of P. amabilis using 11 different physical parameters ...
