One of the cyanobacterial-based bio-fertilisers is Arthrospira platensis (Spirulina platensis), which contains phycocyanin, a blue protein pigment that is abundant in Spirulina sp., that boosts the growth yield and bioactive content of plants. The aim of the current study is to determine the alteration in antioxidant and phenolic content in red cabbage microgreens (Brassica oleracea var. capitata f. rubra) by treating different organs of the plant with phycocyanin from Arthrospira platensis. The phycocyanin application did not significantly affect the phenolic content of the cotyledon leaves. However, soaking with phycocyanin solution significantly affected the phenolic content of seeds. Regarding the antioxidant capacity of the microgreens, no significant effect was detected on the antioxidant activity of the seeds among the phycocyanin concentrations. The phycocyanin application significantly increased antioxidant activity compared to control soaked in deionised water. The results clearly demonstrate that phycocyanin application to seed and cotyledon leaves affected the antioxidant capacity and phenolic content of the microgreens. Although there are several studies about the effects of phycocyanin on growth parameters, this study has different perspectives in terms of the method of phycocyanin application and evaluation of the bioactive compounds in microgreens.

The photosynthetic traits were evaluated using OJIP chlorophyll fluorescence transient. The plants were exposed to a saline condition of 224 mM NaCl, and their ability to form associations with arbuscular mycorrhizal fungi (AMF) was also assessed. We tested both commercial AMF products, containing spores from multiple genera, and isolated AMF spores from Glomus etunicatum and Glomus grape, to determine their ability to infect sago palm roots under high salt conditions. The results showed that sago palms can maintain efficient photosynthesis even at high salt levels. This is likely due to their ability to prevent excessive salt uptake in shoots and water loss from roots by forming lignin deposits in cell tissues. Furthermore, the study found that sago palm roots can form associations with AMF under saline conditions. These findings indicate that sago palms exhibit tolerance to saline environments, making them a promising crop option for areas with low soil quality where other carbohydrate-producing crops cannot tolerate the conditions.

Immature male flower bud explants were used for embryogenic callus induction. The 'Manzano' cultivar showed a higher percentage of embryogenic callus induction than 'Pelipita'. Stereomicroscopic observations revealed that the embryogenic callus was asynchronous, as various stages of somatic embryos were noted. White translucent pro-embryogenic callus was efficiently utilized to establish embryogenic cell suspension. The development of different stages in the regeneration process of embryogenic cell suspension was also recorded. Embryos in the late coleoptilar stage, characterized by an opaque white morphology, were selected and transferred to an appropriate medium to evaluate the germination percentage. We found that the germination rate was highly efficient for both cultivars, exceeding 90% when using these embryos in the selected stage. Additionally, we observed that embryos that were 90 days old showed a 10-12% increase in germination compared to those that were 60 days old, confirming the importance of embryo maturation duration and the selection of embryogenic aggregates through the sieving of suspended cells to optimize regeneration efficiency.

China Title: A comparison of seven macadamia cultivars for suitability to the high altitude and high latitude climate of southern Tibet in China Abstract: The suitability of macadamia trees for different climates has been shown to affect tree growth and fruit quality. In this study, the differences in tree survival rate after frost injury, tree growth, nut mass, kernel quality and yield of seven macadamia cultivars were evaluated for field production in the high altitude and high latitude climate of southern Tibet, and the suitability of macadamia cultivars was determined. The cultivars evaluated were 'Beaumont' ('HAES695'), 'HVA16' ('A16'), 'Hinde' ('H2'), 'Own Choice' ('O.C.'), 'SSCRI-1', 'SSCRI-2' and 'SSCRI-3'. Of these, 'Beaumont', 'A16', 'H2' and 'O.C.' were Australian cultivars and 'SSCRI-1', 'SSCRI-2' and 'SSCRI-3' were Chinese cultivars. The results showed that all seven cultivars grew well under the high altitude and high latitude climate conditions of southern Tibet without continuous frost. 'A16' and 'Beaumont' in addition to their reasonable yield, nut mass and kernel quality, had the higher tree survival rate after frost injury. 'A16' and 'Beaumont' were well adapted to the high altitude and high latitude climate of southern Tibet, followed by 'O.C.', 'SSCRI-1' and 'SSCRI-2', but 'SSCRI-3' and 'H2' were unsuitable. These results indicated that it is possible to produce macadamia in the high altitude and high latitude climate of southern Tibet by planting excellent frost-resistant cultivars, with promising yields and a commercial standard of nut quality.
