Studies on phenology and reproductive biology were carried out in 15 populations of Rauvolfia serpentina (L.) Benth. ex Kurz (2n = 22). Two different sizes of pollen grains (82.5 ± 5 and 52.3 ± 5 µm) with viability up to 85–95 % were observed. The receptivity of stigma was found to be 1 day prior to anthesis between 08.45 and 09.15 a.m. Study revealed that this species is preferentially cross pollinated...
Twenty five populations of Rauwolfia serpentina collected from different states of India were subjected to spectrophotometric and high performance liquid chromatography analyses to study magnitude of variation in total alkaloid and reserpine in roots. Significant variations in the content of total alkaloid (4.82–2.51 %) and reserpine (0.083–0.040 %) have been recorded. The total...
An investigation was carried out with 25 populations of Rauwolfia serpentina to assess variability, association of yield components and their direct and indirect effects on yield. Analysis of variance revealed significant differences among 25 populations of R. serpentina for all the traits. Heritability estimates in broad sense were high for most of the traits and moderate for number of primary root...
