Extended Abstract
Introduction: Cow tail (Smirnovia iranica) is considered a valuable shrub species indigenous and adapted to the sandy lands of the Iranian central regions which besides playing an essential role in the desert cover for soil protection and of forage production, is considered important due to its great medicinal values. Considering the fact that seed germination of this plant does not easily occur due to its hard and solid seed coat, in this study, the in vitro tissue culture and seedling establishment is utilized for the first time in order to surmount the obstacles laid ahead of cow tail seed germination.
Materials and Methods: Scratched seed, unscratched seed and seed embryo of cow tail as different explants were placed in two culture media (MS, MS with free amino acids complex) following surface sterilization, and were exposed to two photoperiod treatments (16 hours of light and 8 hours of darkness as well as absolute darkness) and were investigated in a factorial experiment based on completely randomized design with six replications. Finally, germination percentage (10 days after seed culturing) and shoot length (30 days after seed germination) were evaluated.
Results: The results indicated that significance of the effect of investigated treatment conducted over some in vitro on germination characteristics. It was revealed that the cultivation of seed embryo in MS culture media along with free amino acids complex for 16 hours of light and 8 hours of darkness photo period can be considered as the best in vitro germination method, in terms of seed germination percentage (78.83%) and germinated shoot length (44.83 mm).
Conclusion: In vitro culture can be used to improve germination and seeding production of this species.
Highlights:
- The method for seed dormancy elimination of cow tail plant was introduced.
- The seed disinfection procedure for in vitro culture of cow tail plant was introduced.
- The components of in vitro culture medium for rapid and efficient seed germination of cow tail plant were introduced.

Abstract
Objective: Commercial sugarcane cultivation is often associated with high production costs due to the extensive use of planting material, energy waste, long cultivation periods, rapid deterioration of cuttings after bud establishment, labor-intensive operations, frequent machinery use, and heavy applications of fertilizers and pesticides. This study evaluated the efficacy of pelleting lateral buds from sugarcane stalks to produce single-bud seed pieces suitable for mechanized cultivation at the Sugarcane Development, Research, and Training Institute in Khuzestan, Iran.
Methods: A split-plot experiment, based on a randomized complete block design with three replications, was conducted in 2021 at the Sugarcane Development, Research, and Training Institute (SDRTI) in Khuzestan, Iran. The factors considered were different planting dates—16 August (D1), 16 September (D2), and 17 October (D3)—as the main plots, and pellet types (A1: starch + peat + micro-combi fertilizer; A2: starch + peat + nutritional compounds + potassium silicate + carbendazim fungicide; A3: single-bud without pellet; and A4: 50 setts without pellet as the control) as the subplots.
Results: Pelleting single-bud seeds, particularly in treatment A2 planted in September, significantly enhanced crop establishment. It increased the emergence percentage by 56% and the emergence rate to 2.85 sprouts per day compared to the control. Pelleting also improved growth and quality indices more effectively than the other treatments.
Conclusions: Pelleting single-bud sugarcane seeds with nutrient-enriched coatings improves emergence, supports early crop growth, and facilitates mechanized cultivation. This technique supports mechanized planting by enhancing nutrient delivery and moisture retention at the bud level, contributing to more sustainable, efficient, and cost-effective sugarcane cultivation.
Highlights:
- Using treatment A2 for pelleting significantly boosted the emergence rate of sugarcane single buds by providing essential nutrients.
- Planting in September along with pelleting improved the early growth and establishment of sugarcane plants.
