Reproductive Biology and Prospects for Conservation of Caldesia parnassifolia (Alismataceae)——A Threatened Monocot in China

Caldesia parnassifolia (Bassi ex Linn.) Parl. in China has declined in number in recent years and is increasingly faced with the risk of extirpation arising from anthropogenic changes associated with rapid urbanization and expansion of both agriculture and infrastructure. To aid in provision of the data needed for effective conservation of the species, studies on the habitat, pollination ecology, and breeding system of C.parnassifolia were carried out on natural populations occurring in Southeastern China. Flowering in the study populations extended for more than eighty days beginning in early summer. Floral anthesis occurred in the morning hours and proceeded rapidly, lasting about 45 min. Flowers lasted ca.8h. Caldesia parnassifolia is self-compatible; however autogamy resulted in lower seed set than geitonogamy and xenogamy as well as free pollination. The data on pollen/ovule (P:O) ratio is consistent with a partially selfing and outcrossing mating system. Interpopulational crosses yielded similar seed set to within-population crosses. Agamospermy did not occur in the study populations. Propagation is achieved through seeds as well as through turions which commonly occur in the inflorescences. Flies (Insecta; Diptera) were the most frequent visitors to the flowers of C.parnassifolia; however bees (Insecta;Hymenoptera )composed a larger proportion of effective pollinators. The Syrphidae species Sphaerophoria indiana (Bigot) presents evidence of oligolectic foraging behavior. Recommendations are made on the immediate steps necessary for conservation of Caldesia species in China.

青椒贮藏工艺

1.品种选择：要选择肉质(皮)厚、色深绿，皮坚光亮的晚熟品种，如茄门、二猪嘴、麻辣三道筋等，固不耐藏品种贮期仅为30天左右，而耐藏品种可达50—60天。     

采用不同浓度的钙处理对水蜜桃贮藏性的影响

水蜜桃采用后１％的钙处理，其呼吸作用受抑制，果实的软化减缓，生理病害减少，因而果实的贮藏性提高，贮藏寿命延长，但用３％及其以上浓度的钙处理，则会对果实造成伤害，引起生理病害的发生，从而降低果实的贮藏性，缩短其贮藏寿命。
