This study investigated the impact of constitutively expressed Trichoderma atroviride genes encoding exochitinase nag70 or endochitinase ech42 in transgenic lines of the apple cultivar Pinova on the symbiosis with arbuscular mycorrhizal fungi (AMF). We compared the exo- and endochitinase activities of leaves and roots from non-transgenic Pinova and the transgenic lines T386 and T389. Local and ...

This work was carried out for 5 months from February, 2022 to June, in shadenet house, Department of Horticulture, SHUATS, Prayagraj. The experiment designed according a Factorial Completely Randomized Design (FCRD), using five different adenium hybrids and three types grafting techniques. replicated times. used the were Masai, Cream My Body, Tangerine, Super Moon, Golden Jublee techniques wedg...

Plant grafting is an important technique for horticultural and silvicultural production. However, many rootstock plants suffer from undesirable lateral bud outgrowth, low grafting success rates or poor rooting. Here, we used a root-predominant gene promoter (SbUGT) to drive the expression of a tryptophan-2-monooxygenase gene (iaaM) from Agrobacterium tumefaciens to increase auxin levels in toba...

fruit yield efficiency and some vegetative characteristics of commercial and spur type apple. cultivars was evaluated in dr. nakhjavani field station, orumieh, iran, in 2008 and 2009 growing seasons. apple cultivars included: red spur, red chief, golden spur, yellow spur, fujii, red delicious, cooper spur, red cooper spur, jonathan, golden delicious, oregon spur, jonagold. the experimental desi...

in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...

This paper aims at providing a preliminary study of the effects of different doses of tannery waste containing high amounts of organic substances, mineral elements and heavy metals on growth dynamics and metal accumulation in willow plants. Scions of Salix alba L., clone S61-02, were grown in the open near Pisa (Italy), in pots filled with a natural soil. Willows were pruned for a unique shoot ...

Plum bark necrosis-stem pitting (PBNSP) disease was first observed in 1986 affecting plum (Prunus salicina Lindl.) cv. Black Beaut trees in two orchards in Dinuba, CA (8). All of the Black Beaut plum trees had been whip-grafted with a single cultivar Wickson plum scion per tree to serve as a pollenizer, and all Wickson grafts failed. A year later, the same trees were grafted a second time with ...

Plant defense responses to wounding and herbivore attack are regulated by signal transduction pathways that operate both at the site of wounding and in undamaged distal leaves. Genetic analysis in tomato indicates that systemin and its precursor protein, prosystemin, are upstream components of a wound-induced, intercellular signaling pathway that involves both the biosynthesis and action of jas...

Turhan A., Ozmen N., Serbeci M.S., Seniz V., 2011. Effects of grafting on different rootstocks on tomato fruit yield and quality. Hort. Sci. (Prague), 38: 142–149. The aim of the study was to find effects of tomato grafting on another cultivar. The tomato cultivars used as scions were Yeni Talya, Swanson and Beril. Cultivars used as rootstocks were Beaufort and Arnold. Cleft grafting methods we...
