Objective: Genetic component influencing amygdalin content in apricot kernel is well documented. This study aims to evaluate influence of altitude and seed phenotypic characters on amygdalin content in apricot kernel. Methods: Fruits from 126 genotypes differing in kernel taste and seed coat colour were collected from seven locations from 3008-3346 m asl in trans-Himalaya. Amygdalin content in kernel was determined. Results: Amygdalin content in bitter kernel was significan tly higher (44.6{\textpm}9.0 mg.g-1) than that of sweet kernel (3.1{\textpm}1.8 mg.g-1) with brown seed coat. The geographical elevation had no influence on kernel amygdalin content. Similarly, seed and kernel physical characters, except seed coat color, had no significant effect on kernel amygdalin content. High variability within genotypes was observed suggesting that genotype played significant role on amygdalin content in apricot kernel. Low amygdalin content (2.4{\textpm}1.2 mg.g-1) in apricot kernel with white seed coat phenotype confirmed our earlier finding that the white phenotypic marker is associated with sweet kernel. Conclusion: The geographical elevation had no influence on kernel amygdalin content. White seed coat phenotype can be taken as a marker for low amygdalin content in future studies.

Objective: This study aims to determine how maturation stages of greenhouse-grown beet leaf influence the total phenolic content (TPC) and total flavonoid content (TFC). Methods: Beet leaf was grown under two different passive solar greenhouses in trans-Himalayan Ladakh. Leaves harvested at three maturity stages were evaluated for TPC and TFC. Results: Significant difference in TPC and TFC was observed between the three maturity stages. Midmature leaves had the highest TPC and TFC followed by mature and immature leaves. When TPC and TFC for all maturity stages were averaged, a marked difference in TPC and TFC was observed in beet leaf grown under the two passive solar greenhouses. Higher TPC and TFC were observed in the greenhouse with higher photosynthetically active radiation (PAR) and UV-transmittance. Conclusion: Beet leaf should be harvested at the midmaturity stage for consumer to benefit from elevated levels of phenolics and flavonoids.
