Nutraceutical Potential of Wild Leafy Vegetables Commonly Consumed by Tribal Communities: Cassia tora (L.) Roxb., Acalypha fruiticosa Forssk. and Talinum portulacifolium (Forssk.) Asch. ex Schweinf.

Wide variety of consumable leafy vegetables are present in the nature but most of them are neither utilised nor scientifically investigated. Nutraceutical potential of these plants should be studied to enrich our knowledge, thus making them part of balanced diets. In view of this objective, three leafy vegetables were selected viz.

Divergence in pollen performance between Clarkia sister species with contrasting mating systems supports predictions of sexual selection.

Animal taxa that differ in the intensity of sperm competition often differ in sperm production or swimming speed, arguably due to sexual selection on postcopulatory male traits affecting siring success. In plants, closely related self- and cross-pollinated taxa similarly differ in the opportunity for sexual selection among male gametophytes after pollination, so traits such as the proportion of pollen on the stigma that rapidly enters the style and mean pollen tube growth rate (PTGR) are predicted to diverge between them. To date, no studies have tested this prediction in multiple plant populations under uniform conditions.
