“…Earlier studies have shown that the application of exogenous Ca alleviates the development of cowpeas, Rumex, Jerusalem artichoke, loquat and anger rootstocks, linseed and bean under salt stress (Murillo-Amador et al, 2006;Chen et al, 2006;Xue et al, 2008;Garcıá-Legaz et al, 2008;Khan et al, 2009;Cabot et al, 2009). Exogenous calcium also reduces leaf wilt of salt-stressed date sour jujube by nearly half (Jin et al, 2016). Our study showed that the growth and biomass of Salix matsudana seedlings decreased with increasing NaCl concentration.…”

As the main component of snowmelt agents, NaCl is widely used in northern winters and significantly impacts the expected growth of garden plants in north China. Salix matsudana is also faced with salt stress caused by snowmelt, which seriously affects its development as the main tree species in the northern landscape. However, how exogenous calcium alleviates salt stress in Salix matsudana is not yet clear. In this study, the indicators of growth indices, photosynthetic characteristics and stress resistance were measured by hydroponic assays in combination with three NaCl conditions (0, 50 and 200 mmol·L-1) and five calcium concentrations (0, 2.5, 5, 10 and 20 mmol·L-1). The study’s results indicated that the application of exogenous calcium remarkably promoted the growth of Salix matsudana seedlings under NaCl stress. When the exogenous calcium concentration was 10 mmol·L-1, the plant height and basal diameter of Salix matsudana seedlings increased significantly, and the biomass of all parts reached the maximum (P< 0.05). Exogenous calcium can substantially improve the photosynthesis of Salix matsudana seedlings under salt stress. The photosynthetic parameters, photosynthetic pigment content and photosynthetic product synthesis of Salix matsudana seedlings were significantly increased at an exogenous calcium concentration of 10 mmol·L-1, and the photosynthetic level of Salix matsudana seedlings reached the highest value. The chlorophyll fluorescence parameters (Fv/Fm, Fv/F0) of Salix matsudana seedlings were significantly decreased under different concentrations of NaCl stress. The maximum photochemical efficiency (Fv/Fm) and potential photochemical efficiency (Fv/F0) of Salix matsudana seedlings peaked when the exogenous calcium concentration was 10 mmol·L-1, which was significantly higher than that of the other treatments (P< 0.05). The water use efficiency of Salix matsudana was affected considerably by NaCl stress. The WUE and iWUE peak values of Salix matsudana were significantly higher than those of other calcium concentrations at 10 mmol·L-1 (P< 0.05). Exogenous calcium can increase the activities of CAT, SOD and POD enzymes in Salix matsudana seedlings under different NaCl concentrations. Under NaCl stress, adding exogenous calcium promoted the survival rate and growth of Salix matsudana seedlings. In conclusion, the optimum exogenous calcium concentration for Salix matsudana seedlings was 10 mmol·L-1. High or low concentrations of exogenous calcium did not achieve the best results in alleviating salt stress in Salix matsudana.

“…Peningkatan kandungan K dari penggunaan PEG 10% ke PEG 15% dan 20% diduga ada hubungannya dengan perannya dalam menjaga turgor tanaman dan proses menutup dan membukanya stomata. Unsur K + dan Mg + berperan dalam mengurangi potensial osmotik pada tanaman sehingga dapat mentriger tekanan turgor tanaman untuk melakukan transport berbagai macam solut yang ada di xilem serta mengatur keseimbangan air tanaman (Jin et al, 2016).…”

Tanaman manggis membutuhkan kondisi kering untuk menginduksi pembungaan, namun kekeringan yang berkepanjangan dapat menyebabkan terhambatnya pertumbuhan manggis sehingga respon bibit manggis terhadap kekeringan perlu dipelajari. Penelitian dilakukan mulai Mei sampai Juli 2017 menggunakan rancangan acak kelompok (RAK) satu faktor. Perlakuan terdiri atas 4 taraf konsentrasi polietilena glikol (PEG 6000), yaitu PEG 0%, PEG 10% (setara -0.19 MPa), PEG 15% (setara -0.41 MPa) dan PEG 20% (setara -0.67 MPa) m.v-1. Hasil percobaan menunjukkan bahwa terjadi kekeringan pada daun manggis yang diberi PEG yang terjadi secara perlahan dimulai dari tepi daun yang menguning tetapi tetap hijau di bagian tengah. Konsumsi air terus berfluktuasi sampai akhir percobaan mencapai 33.33 ml pada tanaman dengan PEG 0% dan 10 ml pada tanaman dengan PEG 20%. Peningkatan konsentrasi prolin terjadi dari minggu pertama sampai dengan minggu ketiga setelah perlakuan pada semua tanaman yang diberi PEG, dengan konsentrasi prolin paling tinggi terdapat pada perlakuan PEG 15% dan PEG 20% masing-masing mencapai 22.14 dan 23.46 µmol.g-1. Penurunan bobot kering tanaman semakin tinggi seiring dengan tingginya cekaman yang dialami tanaman. Cekaman yang diakibatkan oleh PEG tidak berpengaruh terhadap kandungan N dan Mg, namun menurunkan kandungan P pada bibit manggis. Kata kunci: evapotranspirasi, kandungan hara, prolin, stres air
