Effect of rootstock on fat content and fatty acid composition of immature pistachio kernels

This study was conducted on pistachio trees (Pistacia vera L., cv Siirt) grafted on four different rootstocks (Pistacia atlantica Desf., P. khinjuk Stocks, P. terebinthus L. and P. vera L.) to elucidate effects of the rootstocks in the fat content and fatty acid composition of early harvested green pistachio kernels. Fat content and fatty acid compositions were determined after harvesting. The fat content of pistachio kernels ranged from 24% on P. terebinthus to 35.4% on P. atlantica. The fatty acid compositions ranged from 10.83% on P. atlantica to 12.17% on P. khinjuk in saturated fatty acids (SFAs); 68.29% on P. khinjuk to 70.09% on P. atlantica in monounsaturated fatty acids (MUFAs) and 18.42% on P. vera to 19.54% on P. khinjuk in polyunsaturated fatty acids (PUFAs). The unsaturated/saturated fatty acid ratio varied between 7.22 and 8.23. In the present study, we found that the fatty acids were affected by the rootstock in pistachio trees. © 2017, Academic Publishing House. All rights reserved

Comparison of some physiological markers prior to and post vitrification in Hypericum perforatum L.

The aim of this work is to present the differences between survival rate of Hypericum perforatum L. shoot tips cryoprotected with PVS2 or PVS3 and to compare some physiological patterns prior to and post vitrification procedure. H. perforatum shoot tips pretreated either with 0.076ìM abscisic acid (ABA) for 10 days or 0.3M sucrose for 16 hours were cryoprotected with two different cryoprotective solutions, PVS2 (10% v/v glycerol, 20% w/v sucrose, 10% v/v DMSO) or PVS3 (50% w/v sucrose, 50% v/v glycerol). Survival rate was determined 7 weeks after thawing. As Table 1 shows we have observed 1.47 to 8.6 times higher survival rates (except for the genotypes 40/7/3 and 42/7/3) using PVS3 after ABA pretreatment, whereas in case of sucrose pretreatment survival rate of most genotypes exposed to the same cryoprotection procedure decreased (except for 29/7/5 and 34/7/1, respectively). Recovered plants were subjected to assessment of some physiological markers. Conductivity, H2O2 and MDA content were determined in recovered samples and their control plants (up to 100 mg FW). Our preliminary results indicate that at least one of the parameters studied exceeded level of control values (prior to cryopreservation) after recovery of cryopreserved samples (Figure 2) with an exception of one sample. Possible effect of these findings will be presented and discussed.vokMyynti MTT, Tietopalvelut 31600 Jokioine
