One or two treatments were applied in June; the first treatment in the early stage of larvae hatching from eggs deposited by females from the summer generation, whilst the second application was carried out about two weeks later. In all the experiments, spirotetramat as Movento 100 SC applied at a dose of 2.25 l/ha effectively reduced the pest population after only a single application (total reduction of larvae after one week post-treatment 75.3-91.4%, and 83.7-97.6% at two weeks posttreatment). Movento 100 SC applied after a single application at a lower dose of 1.8 l/ha had a slightly worse effect (the total reduction of larvae at one week posttreatment was at the level of 58.4-91.3%, and two weeks after application at the level of 56-92.6%) - but in this case only a few larvae at stages L4 and L5 were found on pear shoots. The effectiveness of spirotetramat at both doses after two applications was very high. In comparison with standard insecticides the efficacy of spirotetramat was higher or not significantly different. In two experiments the application of standard compounds such as diflubenzuron and novaluron was not effective in controlling pear psylla and therefore did not prevent damage to pear trees. This may suggest that local populations of the pest are resistant to these measures, especially since they have been used for many years to control other pests of pear trees Streszczenie Badania przeprowadzono w latach 2009-2011. Obejmowały one pięć doświadczeń polowych zlokalizowanych w doświadczalnej kwaterze grusz w Sadzie Doświadczalnym w Dąbrowicach oraz w dwóch prywatnych sadach gruszowych w Lubominie k. Izbicy Kujawskiej i w Brochocinie k. Płocka. Spirotetramat jako Movento 100 SC badano w dwóch dawkach − 1,8 l/ha i 2,25 l/ha. Zabiegi wykonywano w pierwszej dekadzie czerwca na początku wylegania się larw z jaj złożonych przez samice pierwszego pokolenia formy letniej. W pierwszych dwóch sezonach opryskiwanie powtarzano po około 14 dniach. Spirotetramat jako Movento 100 SC w dawce 2,25 l/ha we wszystkich pięciu doświadczeniach wykazał wysoką i bardzo wysoką skuteczność w zwalczaniu miodówki gruszowej plamistej już po jednokrotnym zastosowaniu. Po tygodniu liczba larw ogółem zmniejszyła się o 75,3% do 92,1%, a po dwóch tygodniach o 83,7% do 97,6%. Preparat ten zastosowany jednorazowo w dawce niższej (1,8 l/ha) nie zawsze był tak skuteczny. Na przykład w doświadczeniu w Lubominie jedynie ograniczył liczebność szkodnika (redukcja larw ogółem po tygodniu wyniosła zaledwie 58,4%, a po dwóch tygodniach 56,0%). Jednakże w większości doświadczeń oraz po dwukrotnym zastosowaniu preparat Movento 100 SC także w dawce 1,8 l/ha wykazał wysoką i bardzo wysoką skuteczność zwalczania (89,4-93,5%).

The data collected included tree vigour (expressed as trunk cross-sectional area − TCSA), yield, and fruit weight as well as content of soluble solids in fruit. Based on TCSA, the largest ‘Sylvia’ and ‘Karina’ trees were on ‘F12/1’, and the smallest were on ‘GiSelA 3’. The results revealed that all of the tested rootstocks being compared to ‘F 12/1’, significantly reduced the growth of sweet cherry trees. ‘Sylvia’ trees on ‘GiSelA 5’ and ‘Piku 4’ yielded more than those on ‘F12/1’. The highest cumulative yields of ‘Karina’ were harvested from trees on ‘GiSelA 5’. ‘Karina’ trees on ‘GiSelA 3’, ‘Piku 4’ and ‘Weiroot 72’ performed comparably in cumulative yields to those on ‘F12/1’. Rootstock effects on yield efficiency were consistent between the two cultivars, with the most yield efficient trees on ‘GiSelA 3’, ‘GiSelA 5’ and ‘Weiroot 72’, and the least efficient trees on ‘F12/1’. Trees of both cultivars grafted on ‘GiSelA 3’ produced significantly smaller fruits than those grafted on ‘F 12/1’. The rest of the rootstocks, tested in terms of an effect on fruit weight (with the exception of ‘Karina’ on ‘Weiroot 72’), had a similar value to ‘F 12/1’. Effects of rootstock on content of soluble solids in fruit were modest and statistically insignificant.

Pomiary grubości pni wykazały, że drzewa obydwu badanych odmian czereśni najsilniej rosły na standardowej podkładce kontrolnej F12/1, a najsłabiej na GiSelA 3. Generalnie, wszystkie oceniane podkładki w porównaniu z ‘F12/1’ istotnie ograniczały siłę wzrostu drzew. Z czereśni ‘Sylvia’ zaszczepionych na ‘GiSelA 5’ i ‘Piku 4’ zebrano istotnie wyższe plony owoców niż z drzew na ‘F12/1’. Drzewa ‘Karina’ owocowały najlepiej na podkładce GiSelA 5. Plonowanie drzew tej odmiany na pozostałych podkładkach było porównywalne z drzewami rosnącymi na standardowej podkładce F12/1. W przypadku obydwu odmian wartość wskaźnika intensywności owocowania obliczonego dla drzew szczepionych na ‘GiSelA 3’, ‘GiSelA 5’ i ‘Weiroot 72’ była wyższa niż dla drzew kontrolnych.

After the application of morphactin above the 3rd node of decapitated tulips, the stimulated growth of the 4th internode was clearly observed. On the other hand, NPA and TIBA were slightly effective in stimulating the 4th internode growth of tulips. Endogenous levels of IAA in the 4th internode after the treatment of auxin polar transport inhibitors were determined using gas-liquid chromatography-mass spectrometry (GC-MS) and gas-liquid chromatography-mass spectrometry selected ion monitoring system (GC-SIM) with deuterium labelled IAA (Indole-2,4,5,6,7-d5-3- acetic acid, d5-IAA) as an internal standard, resulted in significant accumulation of IAA in the 4th internode of tulips after the treatment of morphactin. In the treatment of NPA and TIBA, there was almost no such an accumulation of IAA. These results strongly suggest that stimulated growth of the 4th internode of tulips induced by the application of morphactin is the consequence of accumulated endogenous levels of IAA after the treatment. The possible mode of action of auxin polar transport inhibitors in tulip stem growth is also discussed.

Among them, the use of biostimulants is environmental friendly method of stimulating crop productivity, stress resistance, and affecting yield or chemical composition of the plants. The aim of the investigation was determining of the effect of biostimulant treatment on yield and its quality of carrot grown for summer harvest. The experiment was carried out in 2009-2011 in the experimental station of the University of Agriculture in Krakow, south Poland. Two experimental factors were taken into consideration: (1) cultivar: Nandrin F1 and Napoli F1 (2) dose of Aminoplant (foliar application): 1.5 and 3.0 dm3∙ha-1 and control (without Aminoplant). Total and marketable yield, root length, its diameter, leaf mass and leaf : root mass ratio were assessed. The dry matter, soluble sugar, carotenoids and nitrate ions contents were analyzed as main determinants of carrot nutritional quality. Aminoplant influenced not only carrot productivity, but mainly chemical composition of the roots. The present results also suggest that carrot reaction to biostimulant treatment was depended on a cultivar more than on environmental conditions in particular growing seasons. The significant effect of Aminoplant in a dose of 1.5 dm3∙ha-1 on the yield of roots and leaf rosette mass of ‘Nandrin F1’ appeared only in the first year of the experiment. Spraying with Aminoplant in a dose of 3.0 dm3∙ha-1 significantly increased the soluble sugars content in carrot roots of both cultivars but only in 2011. Dry matter content was also affected by biostimulant treatment mainly for ‘Napoli F1’, which showed the lowest dry matter content when sprayed with Aminoplant in a dose of 1.5 dm3∙ha-1. In 2010 control plants contained the greater amount of carotenoids, while in next year roots of plants treated with Aminoplant in a dose of 3.0 dm3∙ha-1 had more these compounds. The significant effect of Aminoplant on nitrates content in carrot roots was observed but were not repeatable in the experimental years, so different climatic conditions modified carrot reaction on biostimulant spraying.

The young trees were grown at a spacing of 25 cm × 1.0 m on a podzolic soil. On the basis of the differences in the thickness and height of the maidens, and the number of lateral shoots and their length, as well as the number of branched trees, the effects of various fertilizers were studied depending on the number of treatments applied to the plants, which were treated either once or twice with such products as granulated manure, Micosat, Humus UP, Humus Active + Aktywit PM, BF Amin, BF Quality, Tytanit and Vinassa. The control plants were not fertilized at all, or fertilized with NPK. The fertilizers were applied the first time to the soil and plants in the nursery in mid-May and the second time in early June. The results showed that using them in a double treatment did not result in improved plant growth in every case. Two applications of humic preparations, the so-called vermiculites (Humus UP, Humus Active + Aktywit PM with the addition of beneficial bacteria), BF Quality, and to some extent also BF Amin gave better results in terms of the quality of maiden trees than a single application of these products, whereas in the case of preparations such as Tytanit and Vinassa, treating plants with them for the second time did not result in a significant increase in the intensity of plant growth in relation to the plants treated only once during the early period of growth Streszczenie W latach 2010 i 2011 w szkółce ekologicznej badano wzrost okulantów jabłoni odpornych na parcha odmian Topaz i Ariwa szczepionych na podkładce M.26.

In addition, pretreatment of PLB-synseeds with 200 mM KNO3 solution, the addition of activated charcoal or coconut water to synseeds, light vs dark culture, short-term (1 month) and long-term (6 and 12 months) low-temperature (4°C) storage, as well as cryostorage were also tested. All treatments resulted in less PLBs than the control treatment. Among all these treatments, only the use of TC medium or incorporation of coconut water into synseeds resulted in “germination” while lowtemperature storage (1-6 months) was only possible under liquid TC. These results would allow for the short-term preservation of Cymbidium germplasm but not for effective cryopreservation.","PeriodicalId":15757,"journal":{"name":"Journal of Fruit and Ornamental Plant Research","volume":"114 1","pages":"135-146"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77029051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Effect of Postharvest Treatments on Flower Quality and Vase Life of Cut Alstroemeria ‘Dancing Queen’","authors":"Choon Sea Yeat, M. Szydlik, A. Łukaszewska","doi":"10.2478/v10290-012-0024-6","DOIUrl":"https://doi.org/10.2478/v10290-012-0024-6","url":null,"abstract":"Abstract Alstroemeria is one of the most popular cut flowers in Europe, due to its postharvest longevity and a wide colour palette. However, premature leaf yellowing reduces the ornamental value of the flowering stems even before opening of the secondary florets in cymes. The aim of this study was to evaluate the use of sucrose, gibberellin and 8-hydroxychinoline citrate as postharvest treatments of cut Alstroemeria ‘Dancing Queen’. Several “flower models” were used to distinguish the effects of the chemicals on senescence of flowers and leaves in the above cultivar. Flowering stems were harvested in November 2011 and March 2012 and the response to treatments for both dates differed: while the longevity of primary and secondary florets was prolonged by the standard preservative (8-HQC+S) in the autumn, there was no difference for the spring collection date. For the March harvest, the secondary flower buds opened faster than for the November harvest, where bud opening was generally hastened by 8-HQC+S. Also, the flower model affected floret longevity and changed the response to the treatments: florets on defoliated flowering stems responded better to the preservative than those on stems with leaves. Florets from different flower models differed in diameter: those from complete stems were usually larger than those from isolated cymes. The secondary florets were much smaller than the primary florets, especially in isolated cymes. Both, GA3 and the standard preservative significantly increased the second floret diameter in all models; however, there were no additive effects of the treatments. GA3 significantly postponed leaf yellowing in all floral models while the sugar-containing preservative had little effect. Generally, the flower model had significant effect on leaf longevity. Streszczenie Dzięki długiej posprzętnej trwałości i szerokiej gamie barw alstroemeria jest jednym z najbardziej popularnych gatunków uprawianych w Europie na kwiat cięty. Niestety, przedwczesne żółknięcie liści obniża wartość dekoracyjną ciętych pędów kwiatostanowych jeszcze przed otwarciem się drugiego pąka w sierpiku. Celem badań było określenie wpływu sacharozy, kwasu giberelinowego i cytrynianu 8- hydroksychinoliny na cięte alstroemerie ‘Dancing Queen’. Wykorzystano kilka “modeli kwiatowych”, aby określić wpływ związków chemicznych na starzenie kwiatów i liści. Reakcja na zabiegi kwitnących pędów alstroemerii ciętych w listopadzie 2011 i marcu 2012 roku była różna: podczas gdy trwałość pierwszego i drugiego kwiatu została przedłużona przez 8-HQC+S jesienią, wiosną nie stwierdzonego tego efektu. Na pędach ciętych w marcu pąki drugorzędowe otwierały się szybciej niż te z listopadowego zbioru, gdzie z kolei 8-HQC+S przyśpieszał rozkwitanie. Model kwiatu wpływał na trwałość i modyfikował reakcję na pożywki: kwiaty na pędach pozbawionych liści lepiej reagowały na pożywkę niż te na pędach ulistnionych. Średnica kwiatów różniła się zależnie od modelu kwiatowego: te na ulistni","PeriodicalId":15757,"journal":{"name":"Journal of Fruit and Ornamental Plant Research","volume":"200 1","pages":"147 - 160"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85780399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
