Root-synthesized cytokinins improve shoot growth and fruit yield in salinized tomato (Solanum lycopersicum L.) plants
Salinity limits crop productivity, in part by decreasing shoot concentrations of the growth-promoting and senescence-delaying hormones cytokinins. Since constitutive cytokinin overproduction may have pleiotropic effects on plant development, two approaches assessed whether specific root-localized transgenic IPT (a key enzyme for cytokinin biosynthesis) gene expression could substantially improv...
متن کاملHETEROSIS AND QUALITATIVE ATTRIBUTES IN WINTER TOMATO (Solanum lycopersicum L.) HYBRIDS
An investigation was carried out at the Research Farm of Olericulture Division of Horticulture Research Centre of Bangladesh Agricultural Research Institute (BARI) to evaluate the heterotic performance in F1 generation of tomato. The hybrids showed significant variation in heterosis. The highest heterobeltiotic effects were observed in the cross P3 x P8 (-18.46%) for earliness, P1 x P6 (8.57 %)...
متن کاملCombining Ability Estimates for Yield Some Traits in Tomato (Lycopersicon esculentum L.) by Line×Tester
12 single crosses (F1) achieved by combining four testers and three commercial lines of tomato were evaluated for their response to water deficit stress and the combining ability of yield and some yield components. The layout was split plots according to randomized complete block design with three replications and three irrigation levels (FC, 60%FC and 40%FC). Crossing among lines and test...
متن کاملEffect of Vermicompost on Growth, Yield and Quality of Tomato (Lycopersicum esculentum L)
Cattle dung vermicompost (VC) was used to prepare different proportions of soil and vermicompost mixtures viz. Soil (control), VC15 (Soil+15% VC), VC30 (Soil+30% VC), VC45 (Soil+45% VC). Vermicompost was chemically analysed for various parameters like pH, Total Kjeldahl Nitrogen (TKN), Total Available Phosphorous (TAP), Total Sodium (TNa), Total Organic Carbon (TOC) and Electric Conductivity (E...
متن کاملYIELD AND YIELD COMPONENTS OF GREENHOUSE, FIELD AND SEED BED GROWN POTATO (Solanum tuberosum L.) PLANTLETS
The aim of the research was to determine field, greenhouse and seed bed performance of plantlets derived from in vitro propagated plantlets of three potato cultivars. Generally, higher values were obtained from the mid-early maturing cultivar Marabel, compare to other cultivars (early cultivar Velox and and mid-early cultivar Concorde) for tuber yield, tuber number and average tuber weight. For...
