Salvia species are an important resource for medicinal industry. This research was conducted to develop an indirect organogenesis regeneration protocol for Salvia officinalis L. via which callus was obtained from leaf and internode explants, among these explants internode explant gave best result on MS medium supplemented with 0.5 mg/l 6-Benzylaminopurine (BAP), 2.0 mg/l 1-Naphthaleneacetic acid (NAA). The maximum percentage (70%) of regeneration was obtained with 0.5 mg thidiazuron (TDZ) from internode explants. Shootlets were highly rooted on MS/2 medium added with 1.0 mg/l indole-3-butyric acid (IBA). In vitro rooted seedlings were successfully acclimatized. This in vitro regeneration system will facilitate further development of reliable procedures for this genus.
To investigate the effect of mulch and different cultivation methods on the quantitative and qualitative yield of oil sunflower (Helianthus annuus L.) in Ahvaz climate, a factorial experiment in randomized complete blocks with three replications in the 2017-2018 crop year was in the research farm of Agricultural Sciences and Natural Resources University of Khuzestan. The first factor includes different types of mulch in five levels (non-application, wheat straw, white plastic, live mulch (mung bean cultivation), and black plastic) and the second factor includes three-level cultivation method (on a flat surface, ridge cultivation, and inside the furrow cultivation). The results showed that in the flat surface and on the ridge, black plastic produced the highest amount of chlorophyll a, b, and In the inside the furrow, the highest chlorophyll a was obtained in the application of living mulch. The highest grain yield and oil yield were obtained from the interaction of wheat straw mulch × in the furrow and wheat straw mulch on the ridge. In addition, the highest harvest index was obtained in the treatment of white plastic mulch on a flat surface with an average of 51.85%. In general, it can be said that the treatment of wheat straw and straw × in the inside the furrow and wheat straw × on the ridge were superior in terms of quantitative and qualitative performance.
