to assessment alfalfa cultivars research project this research has been fulfilled in 2011 at khouzestan agricultural and natural resource research center in southwest of ahwaz in khouzestan province (iran) by position 31º20′ n, 48º40′ e. at first section for evaluation wet forage yield cultivars such as “baghdadi”, “mesasersa”, “yazdi”, “bami”, “nikshahri”, “synthetic” (main factor) and two cut...

The crowns of neighboring trees of similar height do not interdigitate but rather are generally separated by spaces called "crown shyness" gaps. In a black mangrove (Avicennia germinans) forest in Costa Rica, the width of crown shyness gaps was positively correlated with the distance pairs of trees or branches adjacent to the gap swayed in the wind (n = 22; p< .01). Abrasion of buds, leaves and...

Taxodium is a genus renowned for its fast growth, good form and tolerance of flooding, salt, alkalinity, disease and strong winds. In this study, a genetic linkage map was constructed using sequence-related amplified polymorphism (SRAP) and simple sequence repeat (SSR) markers based on an F1 population containing 148 individuals generated from a cross between T. 'Zhongshanshan 302' and T. mucro...

This study determined the difference in oil content from separated parts of clove buds, full bud with crown, without crown and dust (stamen style), only along market sample. Results showed that highest a crown. Oil yield varied buds different geographical regions wherein, Madagascar amount oil.

in vitro propagated and conventional runner propagated plantlets of strawberry (fragaria×ananassa duch) cv. ‘festival’ were transferred to the field and the size of crown for plants derived from both sources of planting material were compared. four sizes of the crown, i.e., < 0.5, 0.5-0.8, 0.8-1, and > 1 cm were taken from both sources of planting material. the results obtained flashed that veg...

The aim was to investigate the relations between diameter at breast height and maximum crown diameter, tree height and other possible independent variables available in stand databases. Altogether 76 models for estimating stem diameter at breast height and 60 models for tree age were formulated using height and maximum crown diameter as independent variables. These types of models can be utiliz...
