ABSTRACT: Phenological features of Ulmus vilosa were studied in Kashmir Valley in relation to leaf sprouting, anthesis, pollen production, fruit setting, development and retention, and leaf and fruit drop at different altitudes in the year 2014-2015. Results revealed that the leaf initiation in this species starts from the third week of April at lower altitudes and second week of May in higher altitudes. Initiation of flowering was observed during the second week of February in lower altitudes and in higher altitudes it starts in fourth week of February in higher altitudes. Whereas the total period of flowering oscillated between 31 days (on higher elevation) and 42 days (on lower elevation).The peak period of anthesis was noticed between 1200 and 1400 h of the day. Fruiting initiation started in fourth week of March in lower altitudes and continued up to fourth week of April, but in higher altitudes fruit initiation starts in second week of April and continues to third week of May. Fruit fall starts third week of April and completed in the third week of May in lower altitudes but in higher altitudes it started in first week of May and completed in first week of June. Leaf fall started in the third week of August and continued to third week of October at lower altitudes but in higher altitudes it started in the first week of August and continued up to first week of October, after which the tree remains leafless up to April.

ABSTRACT: The plantation of Populus deltoides carried out on mass scale is on account of the fact that it takes less time (7-8 years) to reach a height were it can be harvested. On an average basis the plant attains a height of 60-70 feet fetches around Rs 13,000 per tree (210/feet). This way the economic status of general public has enhanced many folds. Because of its commercial importance the people have even converted their rice fields into Populus deltoids nurseries. Though people have gained economically by raising Populus deltoides on a mass scale but under the given environmental conditions of valley it has proved to be health hazardous at the time of its seed formation were in the general public and even the animals have been found to suffer from coughing, sneezing, phlegm, wheezing, breathlessness, irritation in eyes and running nose. The plants once grown and harvested still persists in the form of its horizontally proliferating roots where from multiple plants shootout resulting in less efforts for its further proliferation/growth. In the present investigation we are of the opinion that the plants that grow from their roots should be harvested after three to four years only in order to stop its seeding stage which is more harmful to human health.
