Study on Effects of Ascorbic Acid and Citric Acid on Vase Life of Cut Lisianthus (Eustoma grandiflorum) ‘Mariachi Blue’
The postharvest life of cut Eustoma grandiflorum flowers is limited in open flowers. Therefore a factorial experiment based on a completely randomized design with ascorbic acid (AsA) at 4 levels (0, 100, 200, 300mg L-1) and citric acid (CA) at 3 levels (0, 100, 200 mg L-1) with 3 replications and 3 samples for each replications, was conducted for this purpose. Results indicated that a significa...
متن کاملTreatment with Essential Oils Extends the Vase Life of Cut Flowers of Lisianthus (Eustoma grandiflorum)
Lisianthus (Eustoma grandiflorum cv. ‘Mriachii Blue’) is one of the most important and marketable cut flowers in the world. However, a relatively limited vase life reduces its marketability. The aim of the present study was to evaluate the effects of essential oils in extending vase life of cut flowers of Lisianthus. For this purpose a factorial experiment based on a completely randomized desig...

several methods are available to produce haploid plants. one of the most efficient methods is especially microspore culture. stress as a triggering factor is essential for embryogenesis induction in microspores. in the first experiment, the effect of different thermal stresses including cold treatments and heat stress and the control were evaluated. in the second experiment, the effect of 2,4-d...
متن کاملDamage Functions for Meloidogyne arenaria on Peanut.
Microplot experiments were conducted in 1989 and 1990 to determine the relationship between yield of peanut (Arachis hypogaea) and inoculum density ofMeloidogyne arenaria race 1. Nine inoculum densities were used, ranging from 0-200 eggs/100 cm(3) soil (1989) or from 0-100 eggs/100 cm(3) (1990), and each density was replicated 10 times. In 1989, higher final densities (mean of 1,171 juveniles [...
متن کاملFirst report of Meloidogyne graminis on golf courses turfgrass in Brazil
Plant-parasitic nematodes of the genus Meloidogyne, known as root-knot nematodes (RKN), have an important economic impact on golf course turfgrasses. The most prevalent RKN species associated with grasses are M. chitwoodi, M. graminicola, M. graminis, M. incognita, M. marylandi, M. microtyla, M. minor, M. naasi and M. sasseri. In 2010, slight thickening of the roots and RKN females with unusual...
