The influence of lead on the growth and flowering of Hyacinthus Orientalis specie

Abstract

Experiment was conducted to investigate the growth and flowering at Hyacinthus orientalis exposed to lead toxicity. The experience was organized in five variants, each with three repetitions, and each repetition having 10 bulbs. The experience was organized in five variants, the watering process of the substrate was performed using distilled waterfor the control variant and Pb (NO3)2 solutions for the other variants. The influence of lead on the plant growth and development has been assessed byplant height, number of flowers and the photosynthetic pigmentscontent.The growth in height and capacity of plant flowering wereinhibeted by applying the lead, regardless of the dosage used
