Calabrian Pine

Axillary shoot production was achieved in 6 weeks using excised shoot explants of Pinusbrutia Ten. on a modified Schenk and Hildebrandt medium containing cytokinin. Primary shoots arose from existing axillary buds and secondary buds arose from bases of the primary shoots. Their production could be increased by regulating the cytokinin level and by surgical removal of apical buds from the cultured explants. However, the best performance was achieved with a low level of 6-benzylaminopurine (3 × 10−6 M) or a mixture of 6-benzylaminopurine and kinetin (10−6 M of each). Subsequent transfer to a cytokinin-free medium resulted on average in the production of 43 shoots per cultured explant and up to 67 shoots per clone within 12 weeks. When the primary shoots, which had already produced one crop of secondary shoots, were maintained under conditions favourable for shoot production, a doubling in number was obtained within 4–6 weeks. To encourage further elongation, newly formed shoots were incubated for 2 weeks on a cytokinin-free medium to which 1% activated charcoal was added. The time taken with this method was much shorter than with other published methods and is, therefore, likely to be important for the vegetative propagation and multiplication of selected seedlings of this species.

Stipagrostis drarii, found recently in sandy soils of the Arava Valley, is typical component of sandy soils in extreme desert areas. It is adapted to sand mobility by having the ability to overcome up to 50 cm of sand-cover by producing new shoots from the axillary buds of the leafy culm and adventive roots from nodes close to the new soil surface. Two species of Ambrosia which seem to be relatively new introductions to the flora of Israel are recorded here for the first time. It is not clear if these colonizing species will become established. However, judging from their way of dispersal by many small diaspores and efficient vegetative propagation they are potentially noxious weeds.

SUMMARYThe auxin-transport-inhibiting morphactin chlorflurenolmethylester (CFM; Methyl 2-chloro-9-hydroxyfluorene-9-carboxylate) breaks the dormancy of axillary buds in young coffee plants and produces orthotropic shoots. A concentration of CFM as low as 50 mg/litre induced an average of 24 orthotropic shoots per 6-month-old seedling. This approach could provide a fast and inexpensive method of vegetative propagation for raising disease-resistant cultivars if adult clones respond similarly to the seedlings used here and the treatment does not adversely affect the propagation of induced shoots.

The aim of this work is to study the origin and anatomy of rhizophores in two Asteraceae species from the Brazilian Cerrado: Vernonia herbacea (Vell.) Rusby and V. platensis (Spreng.) Less. In both species, axillary buds from the cotyledonary node give rise to the first rhizophores. As rhizophores develop, these organs branch to form new rhizophores from their axillary buds that constitute a sympodial system of underground branches. Nodes, internodes and axillary buds, protected by cataphylls, are evident in these underground organs. The primary root degenerates and all the root system arises adventitiously from the rhizophores. Under natural conditions, the axillary buds give rise to new rhizophores, but when exposed to the light, these buds develop into aerial stems. When rhizophores are fragmented, each of these structures, which accumulate fructans, are important organs for vegetative propagation mainly in areas subjected to environmental disturbances, such as the Cerrado, where fire and drought frequently occur.

The influence of growth substances, saccharose and yeast extract on the differentiation of monogerm sugar beet and polygerm fodder beet anthers is studied. Callus and roots were found to form on the anthers. After subculture, callus derived from a well determined combination of growth substances differentiated into buds, from which plantlets were obtained in unlimited numbers. After rooting, they were transfermed to the soil where they continued to grow. This suggests the possibility of an adaptation of this method in vegetative propagation of beets.
