Embryos were obtained from unfertilized and undeveloped seeds of satsuma (Citrus unshiu Marc.) cultured on a modified Murashige and Tucker (MT) medium. Embryogenic callus was induced from the hypocotyl region of the embryos. The callus was successfully maintained through subculturing on MT medium with 185 μm ade-nine, 2.8 μm GA3 and 400 mg malt extract/liter, solidified with Gelrite. Somatic embryogenesis occurred from callus subculture on medium containing 50 g lactose/liter and in the absence of plant growth regulators. Somatic embryos developed into plants on medium with sucrose and GA3. Protoplasts isolated from this callus produced somatic embryos through colony formation: subsequently, normal, entire plants were regenerated.

Appreciable Variation

The influence of stage of fruit development and plant growth regulators on somatic embryogenesis and the relation of cultivar response on somatic embryogenesis and subsequent plant development have been investigated in eight cultivars of pecan [Carya illinoensis (Wangenh.) C. Koch]. Explants from the micropylar region of the ovule were more embryogenic when removed from fruits in the liquid endosperm stage than were intact ovules from less-mature fruits or from cotyledonary segments of more-mature fruits. Explants conditioned on medium containing auxin alone or auxin + cytokinin produced more somatic embryos than medium containing cytokinin alone. Under the conditions of this study, frequency of embryogenesis, as well as the germination of somatic embryos leading to plant development, indicated appreciable variation among cultivars. Plant development was greatest by far from somatic embryos of `Schley' than other cultivars studied.

Abstract Passiflora xishuangbannaensis (Passifloraceae) is endemic to a few sites of Mengyang nature reserve in Yunnan, Xishuangbanna and less than 40 individuals have been recorded. Nine Passiflora species are endemic to Yunnan with most species occurring in South America, making P. xishuangbannaensis highly significant and emblematic to the conservation work in the region. This study is designed to provide the first protocol for in vitro organogenesis and plant regeneration for ex situ conservation and reintroduction for an Asian Passiflora species. Using internodes, petioles and tendrils we optimize calli formation and root elongation using several plant growth regulators, individually or in combination. We also assess the genetic stability of regenerated cells. The maximum callus induction and shoot bud differentiation were both achieved on half Murashige and Skoog basal medium supplemented with 4.44 µM 6-Benzylaminopurine and 1.08 µM 1-Naphthaleneacetic acid. The best rooting was achieved from 30 days old, regenerated shoots on half Murashige and Skoog basal medium supplemented with 1.08 µM 1-Naphthaleneacetic acid. Micropropagated plants were subjected to inter simple sequence repeat markers analyses. Collectively, 86 bands were generated from 6 primers of which 12 bands were polymorphic, showing genetic variation between the regenerated plantlets and the original plant. Response to plant growth regulators was more specific than most other studies using South American species, which could be explained by the morphological and physiological differences between South American and Asian Passiflora species
