“…In the current investigation, thirteen phytosterols in four bi-clonal tea seed stock oils were quantified (Table 1). According to Patel et al (2020), the oil content of bi-clonal seed stocks ranged from 20.84 to 21.90%. Four bi-clonal tea seed stock oils varied in their phytosterols level and composition (Table 2).…”

The phytosterols are naturally occurring, physiologically active substances found in foods of plant origin. In present study, the phytosterols profile of four bi-clonal tea seed stock oils viz., TS 462, TS 464, TS 491, and TS 506 released from Tocklai are presented. Phytosterols were evaluated using GC-FID. Among the phytosterols, 24-methylene cycloartan-3-ol was recorded as the most abundant sterol in tea seed oil, accounting for 31% of total phytosterols. Results showed that the majority of the sterol diﬀerences were significant (p 0.05). TS 506 has the highest 24- methylene cycloartan-3-ol (476.03.7 mg kg-1) followed by TS 491 (475.97 mg kg-1). β-sitosterol, cycloartenol, canophyllol, lanosterol and campesterol were also present with their contents of 371.03 ± 0.26, 291.38 ± 0.12, 120.44 ± 0.13, 89.12 ± 0.19 and 69.05 ± 0.24 mg kg-1 respectively. The outcomes of the present study provided a foundational understanding of the phytosterols profiles of the four bi-clonal tea seed oils and highlighted their similarities and diﬀerences.

Background: This study investigated the relationship between the flower morphology and fruit yield of tea plants. Tea plants have late self-incompatibility, and cross-pollination can improve fruit yield. However, fruit yield considerably differs among tea varieties. Other factors might affect pollination and fruit yield. This study analyzed 106 tea varieties to determine the relationship between flower morphology and fruit yield.Results: The average fruit yield per plant of the tea varieties exhibited a positively skewed distribution. The higher the yield was, the lower was the proportion of the varieties. According to the relative position between the anther and stigma, the tea varieties were divided into the stigma and anther superior groups. Multiple relationships were observed between floral morphology and fruit yield. The stigma superior group accounted for approximately 85% of the population, and fruit yield was significantly higher in the stigma superior group than in the anther superior group. The longer the pistil was than the stamen, the higher the fruit yield was. The effect of the style width on fruit yield was opposite between the groups. In the stigma superior group, the wider the style width was, the higher was the fruit yield. By contrast, in the anther superior group, the wider the style width was, the lower was the fruit yield.Conclusion: Flower morphology affects the fruit yield of tea plants. In tea breeding, the stigma being higher than the anther is conducive for harvesting fruit. Moreover, the increase in the style width is beneficial for increasing fruit yield and might help pollinating insects in contacting the stigma.
