Effects of Temperature on Asymbiotic Seed Germination of Himantoglossum robertianum (Loisel.) P.Delforge

Kastamonu Üniversitesi Orman Fakültesi Dergisi, 2022
Aim of study: Despite protection by international agreements, millions of orchid tubers are harvested from their natural distribution areas each year. Of these species, Himantoglossum robertianum is locally threatened due to overharvesting and requires precautionary measures to ensure its protection.

Outbreeding and asymbiotic germination in the conservation of the endangered Italian endemic orchid Ophrys benacensis

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2010
Abstract The Insubric bee orchid, Ophrys benacensis (Reisigl) O.E p = 0.024, Student’s t‐test), whereas other complex organic media inhibited germination. We conclude that both pollen and ovules have inherent developmental problems that can be partially overcome by outbreeding with larger populations.

Asymbiotic germination of Odontoglossum gloriosum RCHB.F (Orchidaceae) under in vitro conditions

In Vitro Cellular & Developmental Biology - Plant, 2006
An efficient seed germination system was developed for an endemic and endangered orchid of the prairies of Bogota, Colombia. The effects of three culture media [Murashige and Skoog (MS) salts (1962); Knudson C (KC) salts (1946); and Hydro-Coljap® salts], activated charcoal [0 and 0.5% (w/v)], α-naphthaleneacetic acid (NAA; 0.0, 2.68 and 5.37 μM), and ...

EFFECT OF MEDIUM COMPOSITION ON ASYMBIOTIC SEED GERMINATION OF FIVE PHALAENOPSIS SPECIES

Acta Horticulturae, 2010
Phalaenopsis has become one of the most important flowering potted plants in the world. In order to create novel flower colors and types, various species have been introduced in breeding programs. For the conservation and sustainable utilization of the germplasm, here, we investigated the effect of medium composition on the asymbiotic germination and ...

A classroom exercise in hand pollination and in vitro asymbiotic orchid seed germination

Plant Cell, Tissue and Organ Culture, 2008
While many scientific reports on orchid seed germination provide germination protocols, few provide concise descriptions of plant selection, hand pollination, and asymbiotic seed culture for use in classroom exercises. Another major limitation for conducting orchid seed germination exercises is the availability of seeds or flowers to pollinate. In this

In vitro asymbiotic seed germination and seedling growth of Ansellia africana Lindl.

Scientia Horticulturae, 2010
The effects of sodium hypochlorite treatment and growth medium on in vitro seed germination and seedling growth of the leopard orchid (Ansellia africana Lindl.) were investigated. Forty minutes treatment of seeds with 1.75% sodium hypochlorite stimulated germination (70.6%) and seedling development when measured at Stage 5 (emergence of first leaf) on ...
