“…In the present study, unfertilised and high-fertilised plants did not differ in photosynthetic rate (P. Villar-Salvador, unpublished data) but RGC was positively correlated with shoot size, suggesting that a physiological process linked with the size of the shoots, for instance the total assimilation capacity of the individuals or the amount of stored nutrients and non-structural carbohydrates, might have determined part of the RGC differences among treatments. RGC has been considered as a predictor of the outplanting performance because it is a measure of the vigour of the plants and/or the stress resistance of plants (Burdett et al, 1983;Simpson, 1990). In accordance with this, plants with a higher RGC showed a lower mortality and grew more than those with low RGC.…”

In this study we have addressed the effect of nitrogen fertilisation and shading used during nursery growth on the functional quality of Quercus ilex L. (holm oak) seedlings and their outplanting performance in an abandoned continental Mediterranean cropland. Three N fertilisation regimes: high and low fertilisation (154 and 34 mg N per plant, respectively) and no fertilisation, combined with two shade levels (full sun and 45% shade) were studied. Fertilisation increased the shoot size, shoot to root mass ratio (S/R), root N, and both shoot and root P concentration of the plants produced in the nursery. Fertilisation also enhanced the capacity of new root formation. Neither tissue K nor root mass was affected by N fertilisation. Shading increased S/R and root K concentration but reduced both shoot and root N concentration. Two years after planting, unfertilised seedlings had higher mortality and grew significantly less than those cultivated at both a low and a high fertilisation level. Shading during nursery growth had no influence on the outplanting performance of holm oak seedlings. Plants with a larger shoot and higher S/R had lower mortality and grew faster than those with a smaller shoot and lower S/R. Outplanting performance of holm oak seedlings was related with root N and P concentration and with RGC. No relationship was found with either shoot nutrient concentration or root mass. We conclude that high N fertilisation of holm oak seedlings in the nursery can improve their early field establishment in the afforestation Mediterranean abandoned croplands. #

“…RI ratio is important for it can represent the ratio of height to diameter of plant. It has been reported that seedlings with a SH/RCD ratio are more resistant to the stresses resulting from snow and living cover and that their development rate is greater after planting (Burdett, 1983;Burdett et al, 1983). Aldhous (1975) stated that this ratio should be lower than 6.0.…”

Article Info Received : 11.01.2014 Accepted : 12.06.2014 In the present study, effects of vermicompost treatment tried to be determined on some morphological and physiological seedling quality characteristics of one -year Scots pines. Experiments were set according to random plots experimental design including 14 trials with 3 repetitions. With this aim, seeds obtained from seven different sites (origins) of mixed Scots pine stands which naturally grow in the Western Black Sea Region of Turkey were used in the experiments. At the end of the vegetation period, important physiologic and morphologic parameters of seedlings in the plots, SH, RCD, TDW, RDW and total N rate were detected. After that, RI, V and QI rates, each of which is also important rational indicator in seedlings for height, root collar diameter and weight balance, were calculated with the help of morphological data. Effects of VC treatment were found to be statistically significant on all the development parameters measured in seedlings in seven origin groups. It was determined in all morphologic parameters that the best development rate was observed in Goktepe originating seedlings in both VC treatment and control groups while Geyikgolu originating seedlings showed the least development performance. It was observed from the correlation analysis that there is a positive relation between morphologic and physiologic quality criteria. It was also determined according to the results of multivariable regression analysis that elevation of the sites where seedlings were picked up was more effective on the development of seedling development than the aspect of the sites. Results of the study were found to be convenient with the related literature and showed that VC treatment contributed positively to the development of Scots pine seedlings taken from seven different origins.

“…However, by March, root growth potential was greater in seedlings hardened under warm temperatures (NDW, NDWF, and SD regimes) compared with the cool-temperature OD regime. High levels of root growth potential are desirable for planting stock [6,33]. These results show that root growth potential can be varied using environmental treatments during hardening.…”

-Picea mariana (Mill.) B.S.P. seedlings were hardened for overwintering under four regimes. In three regimes, seedlings were kept inside a heated greenhouse for 11 weeks during and after dormancy induction (August to mid-November), with either 1. Natural daylengths (46°31' N) and warm temperatures of 20 °C or more (NDW), 2. As 1, but fertilized (NDWF) or 3. As 1, but with shortened daylengths (SD). In the fourth regime (OD), seedlings were hardened outside at naturally declining temperatures and daylengths without fertilizer. Seedlings hardened in any warm temperature treatment had buds with more needle primordia and shoots more resistant to desiccation than OD seedlings. Initially, cold hardiness tended to be greatest in SD seedlings. As hardening progressed OD seedlings became equally cold hardy to SD. In late November when all trees were outside, NDW seedlings were usually least cold hardy. Spring root growth potential was least in OD seedlings.cold hardiness / desiccation / needle primordia / transpiration / water potential Résumé -Effets de la longueur du jour, de la température et de la fertilisation sur la résistance à la dessiccation et au froid, et au potentiel de croissance de plants de Picea mariana. On a soumis des semis de Picea mariana (Mill.) à quatre traitements pour les endurcir au froid en vue de la période hivernale. Pour trois traitements les plants ont été installés sous serre chauffée pendant 11 semaines, pendant et après l'induction de la dormance, avec les 3 modalités suivantes : (1) longueur naturelle du jour (latitude 46° 31' N) et chauffage à une température égale ou supérieure à 20 °C (NDW); (2) comme le traitement 1, mais avec fertilisation (NDWF); (3) comme le traitement 1 mais en jours courts (SD). Pour le quatrième traitement (OD) les plants ont été endurcis à l'extérieur avec la baisse de température et la diminution de la longueur des jours des conditions naturelles, sans faire appel à une fertilisation. Les plants issus des traitements comportant une phase sous serre chaude présentaient des bourgeons ayant davantage d'ébauches foliaires et des pousses plus résistantes à la dessication que les plants du traitement OD. Dans un premier stade, l'endurcissement au froid des plants SD tendait à être plus élevé. Ultérieurement celui des plants OD est devenu équivalent à celui des SD. Fin novembre, tous les plants étaient à l'extérieur, les plants NDW étaient moins résistants au froid. Le potentiel de croissance racinaire au printemps était moins élevé pour les plants OD. endurcissement pour la résistance au froid / dessication / ébauche racinaire / transpiration / potentiel hydrique
