“…Callus browning is one of the biggest obstacles to the normal regeneration process, and it has been observed in Cattleya (Lchihasshi and Karo et al 1977), chestnut (Vieitez et al 1983), olive (Ruigni 1984), apple (Block andLankes 1995), actinidialindl (XiaoXingguo andHirsch 1996), cymbidium orchids (Pindel and Miczynski 1996), and pine (Hanna et al 2000). There is evidence to show that callus browning is associated with a polyphenol oxidase (PPO) catalyzed reaction (Laukkanen et al 1999).…”

Being the crucial step for rice transgenic manipulation, callus culture from mature seeds is severely restricted by browning of induced calli, especially in the case of indica (Oryza Sativa L.) rice. Once this browning occurs, the callus will die and no embryonic calli can be obtained for regeneration. Here we report an induction procedure that overcomes callus browning was found. To clarify the inheritance pattern of callus browning, two reciprocal crosses F 2 and two backcrosses BC 1 were made between indica cultivar inbred lines 93-11 and YueTaiB (YTB) which produced normal and browning respectively in the same induction medium. The ratio of browning to normal in the reciprocal F 2 and backcross (BC 1 ) populations tested was approximately 1:3 and 1:1, respectively, these results indicate that callus browning is controlled by one single chromosomal locus which is tentatively named Ic1 (Induced callus 1). The genetic mapping of this locus was carried out using microsatellite markers (SSR) in a 216 extremely browning F 2 seed callus. The analysis of genetic linkage indicated that one single locus that mapped to chromosome 1 was correlated to callus browning, and the closest marker in this study was mapped within 1.9 cM from the target locus.

“…Similar results were obtained for apices and nodes in culture establishment of basal sprouts of Castanea sativa Mill. (Vieitez et al, 1983), highlighting the topophysis effect on the rate of propagation. Different results were obtained by Yu and Reed (1995) for hazelnut explants from shoot tips, which showed initial leaf expansion, followed by explant death without shoot development.…”

a b s t r a c tCorylus avellana L. represents an economically important crop in the European Union. Several protocols of hazelnut micropropagation have been tested but have not yet provided effective methods to allow largescale propagation for commercial purposes, due to poor proliferation and yield. The aim of this work was to study the in vitro effects of coconut water (CW) in combinations with gibberellins and cytokinins on proliferation and growth of hazelnut in vitro and the effect of explants orientation on shoot growth. Single axillary buds from mature trees of 'Tonda Gentile delle Langhe' cultivar collected from suckers and crown were cultured on a modified DKW semi-solid basal medium enriched with coconut water, BAP, IAA and GA 3 in several combinations. The addition of 20% coconut water increased the number of adventitious shoots per explant and the combination of 2 mg/L BAP, 0.01 mg/L IAA and 0.5 mg/L GA 3 promoted multiplication and shoots elongation. Shoot multiplication and growth were also affected by explant orientation. The highest rates occurred with sucker explants in the horizontal position.

“…In general, the micropropagation of adult trees is more feasible when tissues that retain physiologically juvenile characteristics, such as basal shoots and stump sprouts, are used [18,59,60]. Several different authors have achieved the micropropagation of chestnut using this type of material [26,39,51,55,56,[61][62][63][64][65][66][67]. Mert and Soylu [68] studied the use of dormant buds, with the extending of the explant collection period, although rooting of the shoots was not achieved in this work.…”

Castanea is a hardwood forest genus of considerable agro-economic importance for both timber and nut production. Chestnuts are one of the most significant nut crops in the temperate zone. However, this species is threatened by pollution, social factors, economical changes, and two major fungal diseases: ink disease (Phytophthora spp.), and chestnut blight canker (Cryphonectria parasitica). Similar to other wood species, chestnuts are difficult to propagate both generatively by seed and vegetatively by means of grafting or cuttings. Biotechnological methods such as in vitro culture have been developed in the last few years as an alternative to conventional vegetative propagation. Biotechnology plays a very important role not only in the propagation of selected individuals (being used at a commercial level), but also in its short-term preservation, and offers the possibility of preserving the propagated material in the medium-term (cold storage) or long-term using cryopreservation.
