Classification Of Turkish Plantago L. Species Using Numerical Taxonomy, Betül Tutel, İrfan Kandemi̇r, Semra Kuş, Aykut Kence
Turkish Journal of Botany
Twenty-three Plantago L. taxa belonging to 2 subgenera (Euplantago Harms and Psyllium (Juss.) Harms) were classified by numerical taxonomic methods. A total of 36 morphological and ecological characters were utilised for numerical taxonomic analysis of Plantago taxa. The classification obtained by numeric taxonomic methods was compared to that obtained by conventional methods. In general, both of the classifications agreed well, except for the section Hymenopsyllium Pilger being clustered under the subgenus Psyllium contrary to the conventional classification.
In Vitro Regeneration Of Sandal (Santalum Album L.) From Leaves, Abdul Mujib
In Vitro Regeneration Of Sandal (Santalum Album L.) From Leaves, Abdul Mujib
Turkish Journal of Botany
The first successful induction of adventitious shoot buds on Santalum album L. leaves is reported. De novo shoots were induced directly on leaves without any callusing stage. A leaf length of 0.5-1.5 cm only showed bud inducing potential. Bud formation occurred on both MS and WPM basal media, although, liquid media were more responsive. Among the plant growth regulators, BAP at low concentrations (0.44 and 2.22 µM) was effective in this organogenetic process but exogenous auxin application failed to illicit a similar morphogenetic response. Epiphyllous shoot formation was more pronounced on leaf lamina in which the dorsal and ventral leaf …

Purification And Partial Characterisation Of An Acid Lipase In Germinating Lipidbody Linseedlings, Reda Helmy Ahmed Sammour
Purification And Partial Characterisation Of An Acid Lipase In Germinating Lipidbody Linseedlings, Reda Helmy Ahmed Sammour
Turkish Journal of Botany
Electrophoretic analysis of germinating linseed proteins showed a gradual decrease in the quantity of a protein with a molecular weight of 42 kDa. This protein accumulates after 36 h of germination in synchronisation with an increase in lipase activity, and a decrease in the quantity of the total lipids. The 42 kDa subunit was found to be a lipid body membrane protein. This protein was isolated and identified by immunoprecipitation as a subunit of lipase. The linseed lipase acted on a wide range of triacylglycerols and had optimal activity at pH 4.7. The activity of the enzyme was slightly affected …
In Vitro Mass Propagation Of Cucumis Sativus L. From Nodal Segments, Naseem Ahmad, Mohammad Anis
In Vitro Mass Propagation Of Cucumis Sativus L. From Nodal Segments, Naseem Ahmad, Mohammad Anis
Turkish Journal of Botany
An efficient reproducible protocol for the in vitro multiplication of cucumber (Cucumis sativus L.), an important vegetable crop, was developed from nodal explants. Addition of casein hydrolysate to the shoot induction medium (MS + BA) significantly enhanced the number of multiple shoots or growth of the regenerants. Optimum shoot regeneration was observed on Murashige and Skoog (MS) medium containing 1.0 µM 6-benzyladenine (BA) and (200 mg/l) casein hydrolysate. Rooting of isolated in vitro raised microshoots was readily achieved with (1.0 µM) \alpha-naphthalene-acetic acid (NAA) in 1/2 MS. The plantlets thus obtained were successfully established in a greenhouse.

Post-Fire Dynamics Of Cistus Spp. In A Pinus Brutia Forest, Çağatay Tavşanoğlu, Behzat Gürkan
Post-Fire Dynamics Of Cistus Spp. In A Pinus Brutia Forest, Çağatay Tavşanoğlu, Behzat Gürkan
Turkish Journal of Botany
The population dynamics of 2 species of Cistus L. (C. salviifolius L. and C. creticus L.) were studied along a post-fire successional gradient in Pinus brutia Ten. forests in Marmaris National Park, Turkey. The population density of Cistus spp. was 16 individual m^{-2} at the end of the first year after fire and then decreased exponentially (r^2 = 0.926, P < 0.001) the second year after fire to later successional stages. Total projected foliage cover of Cistus spp. was 26% by the end of the first year after fire, it increased to approximately 38% during the second year after fire and decreased linearly (r^2 = 0.872, P < 0.01) beyond this time. Rates of establishment of Cistus spp. were high in the first year after fire but were low in subsequent years and most of the Cistus plants flowered during the second year after fire. There was a significant positive relationship between the density of new seedlings of Cistus and cover of Pinus brutia trees in the sixth year after fire (r^2 = 0.242, P = 0.002). Seed yield of Cistus was reduced due to predation of seed capsules by Bruchid insects. Both species of Cistus were shown to be typical post-fire colonisers in terms of timing of recruitment and post-fire population dynamics. The major factors responsible for the decrease in density of seedlings of C. salviifolius and C. creticus are likely to be the mortality of young seedlings due to summer drought and competition among seedlings and with P. brutia trees. It is suggested here that the species considered have fire-dependent establishment behaviour and an increase in population is restricted to early post-disturbance in P. brutia forests in Turkey, as in other Mediterranean regions.
