These two lines of evidence suggest that long-distance transport of photosynthate is initiated in this species by a process analogous to phloem loading of minor veins in leaves of flowering plants. Two sets of experimental observations suggest that sugar loading in Polytrichum is coupled with the ...
During the Cretaceous, as broad-leaved flowering plants evolved leaf forms similar to those seen in many flowering plants today, they had to develop physiological responses to changes in the supply of basic resources such as [CO2]. As the amount of [CO2] varied, the anatomy of the leaves ...
While Ned Lomax,head gardener of Bodnant Garden, said, "Some plants are actively growing or flowering now as a response to the mild and wet weather following the long, dry summer when growth wasn't possible."With temperatures expected to drop closer to the usual average, the second spring ...

Goji (Lycium barbarum) is an important economic crop that is widely cultivated in Northwest China and is known as superfood. Goji plants are often affected by powdery mildew (Arthrocladiella mougeotii) in the field, resulting in considerable reduction in
FloweringGibberellins (GAs)ZantedeschiaThe effect of gibberellic acid (GA 3 ) on the carbohydrate accumulation in relation to vegetative growth of Zantedeschia 'Black Magic' plants undergoing transition to flowering was investigated. In response to GA treatment the carbohydrate level increased independently...
Indeed leaves of every degree of superficial area can be found amongst the lobed ones on the climbing stem of ivy, and the entire ones of the flowering branch. Sir John adds that ``the form of the inner edge [of the beech] ... decides that of the outer one.'' He does not seem ...
