“…3) and the volume of biomass was not influenced. This particular result seems to be in contrast with the findings of the other authors reporting the ability of BRs to raise the survival rate of plants and to protect them against stresses (Kagale et al 2006;Li et al 2008;Divi et al 2010).…”

“…For example, the positive effect of BRs on thermal stressed plants were documented in the case of rise seedlings (Fujii et al 2001) and cucumber (Cucumis sativus), on water-stressed wheat (Triticum aestivum) (Sairam 1994) and radish (Raphanus sativus) (Kommavarapu et al 2013). As for woody species, Li et al (2008) tested the soaking of Robinia pseudoacacia seedlings in BRs solutions (0-0.4 mg·l −1 ), the results showed that soaking roots in BRs prior to planting significantly increased the survival and growth of seedlings (reduced water and transplant stresses). The best results were in the 0.2 mg·l −1 BRs treatment.…”

ABSTRACT:We tested the influence of exogenous application of brassinosteroids (BRs) on survival, growth and biomass production of Scots pine (Pinus sylvestris) seedlings. BRs are natural substances, supposedly having many positive effects on plants such as improving growth, stress tolerance, survival and biomass production. One part of the seedlings was treated with a low concentration of synthetically prepared BRs and the other part was designated as the control without any treatment. Mortality, height and root collar diameter were measured in two subsequent years, the root-to-shoot ratio of biomass volume was determined in autumn 2013. The application of BRs significantly slowed height and radial growth of pine. The height increment of the BRs-treated seedlings was lower by 11% between 2012 and 2013 compared to the control. The increment in root collar diameter (2012)(2013) in the BRs-treated seedlings was lower by 13% than in the control. The BRs-treated pines also experienced a significantly higher mortality compared to the control. No significant influence of BRs on biomass production was found.

We tested the influence of a synthetically-produced brassinosteroid compound (2α,3α,17βtrihydroxy-5α-androstan-6-one) on seed germination in Norway spruce, Scots pine, Douglas fir and English oak. Before germination, 400 seeds of each species were steeped in a brassinosteroid solution and then placed for germination in a growth chamber under (i) optimal humidity and (ii) temporary drought stress (except for oak). Drought stress significantly reduced the germination capacity and germination rate in the control treatments of Norway spruce, Scots pine and Douglas fir. Nonetheless, the application of brassinosteroid significantly reduced the drought-stress effects in seeds of Norway spruce and Scots pine. The drought-stressed Douglas fir did not respond positively to the brassinosteroid application. English oak was germinated only under the optimal humidity regime and no differences in germination were detected between the control and brassinosteroid-treated acorns.

“…Di Korea, black locust telah menghabiskan biaya cukup besar untuk pembasmiannya (Lee et al, 2004). Black locust juga dikategorikan sebagai jenis invasif di beberapa negara Eropa termasuk Polandia (Rahmonov, 2009) (Xu et al, 2009;Li et al, 2008;Liu et al, 2013;Yang et al, 2014). Sementara itu, perlakuan interval penyiraman terdiri dari 3 tingkat yakni penyiraman 1 hari sekali, 3 hari sekali, dan 7 hari sekali selama 6 minggu (Mazher et al, 2007;Mona dan Amin, 2013).…”

Black locust (Robinia pseudoacacia) is a native species from North America and it has spread to Europe and Asia. Black locust is also one species used for land rehabilitation in semiarid and arid areas. However, adaptability of black locust on their distribution area is quite disturbing due to its invasive potential that tends to suppress the growth of native plants. The purpose of this study is to examine the effect of drought stress through watering volume and watering intervals treatments on physiological behavior and growth of black locust seedlings, and to analyze the level of black locust on drought tolerance through water use efficiency (WUE) character and chlorophyll content. The watering volumes are 30-40 % of field capacity representing drought conditions and 70-80 % of field capacity representing good water conditions, while the watering intervals are 1, 3 and 7 days. Trend analysis is used to analyze the data. The results indicate that the lower watering volume (30-40 %) and the longer the watering interval (for 7 days), the lower the photosynthesis and transpiration rate, stomatal conductance and growth (height, diameter, shoot dry weight and root) of plants, but the higher the WUE and chlorophyll content. Increasing WUE and chlorophyll content are two indicators indicating that black locust is able to adapt (tolerant) to drought stress situations. Therefore, the use of black locust for dry land reclamation requires special attention and careful strategy to avoid its invasive impact in the future.Keywords: black locust, drought, invasive species, water use efficiency, chlorophyll content. (Liu et al., 2013). Sementara itu, tanaman di luar daerah arid maupun semi arid juga sering mengalami defisit air pada siklus hidupnya (Chaves et al., 2002) yang penyebabnya termasuk perubahan signifikan intensitas dan frekuensi suhu bumi serta pola curah hujan, peningkatan suhu atau penurunan kelembaban yang cepat yang mengakibatkan kondisi defisit air Penurunan tekanan turgor yang bersamaan dengan meningkatnya asam absisat bebas pada daun menyebabkan penyempitan stomata (Nilsen dan Orcutt, 1996). Penutupan dan/atau penyempitan stomata menghambat proses fotosintesis, hal ini menyangkut transportasi air dalam tubuh tanaman dan menurunnya aliran karbondioksida pada daun (Nilsen dan Orcutt, 1996; Zlatev dan Lidon, 2012). INTISARI Black locust (Robinia pseudoacacia) merupakan tanaman asli Amerika Utara dan telah tersebar ke Eropa dan Asia serta menjadi salah satu spesies yang digunakan untuk rehabilitasi lahan semiarid dan arid. Walau demikian, kemampuan adaptasi black locust pada daerah persebarannya cukup meresahkan disebabkan jenis ini memiliki potensi invasif yang cenderung menekan pertumbuhan tanaman asli setempat. Tujuan penelitian ini adalah untuk mempelajari pengaruh cekaman kekeringan berupa volume penyiraman dan interval penyiraman terhadap perilaku fisiologis dan pertumbuhan bibit black locust, serta untuk menganalisis tingkat toleransi black locust terhadap kekeringan melalui karakter efisie...
