2年生盆栽桑樹植株,在一年修剪4次方式下,不同季節修剪後至萌芽所需日數、冬季較春、夏、秋季為多,其萌芽率則較低。而經催芽處理後,以冬季催芽最佳,其次依序為秋、春及夏季。 樹體養分之變化,在碳水化合物方面,其枝條、樹幹或根部之主碳水化合物及澱粉含量隨著新梢生長而增加,以秋、冬或夏季修剪之含量較高,春季修剪之含量為最低;唯全糖含量在秋季修剪下蓄積較多,其他生長過程變化較小。氮素方面,樹體之全氮及蛋白態氮含量在春季或冬季修剪下隨著新梢生長而降低,在夏季或秋季修剪下則隨著新梢生長而增高 ...

Habitat loss and fragmentation for an old‐forest species is driven by severe wildfire and drought
We examined the long‐term trends in habitat for California spotted owls and attributed habitat changes to specific drivers. We found that the 43% decline in habitat from 1985 to 2022 could primarily be attributed to wildfire and drought. Habitat patches also became smaller and more isolated over time.

The Great Dividing Range as a driver of genetic divergence in a low‐dispersing dragonfly
Population genomic analyses revealed low genetic differentiation and no discrete population structure across the Great Dividing Range, indicating widespread gene flow in Synthemis eustalacta. Genetic divergence was associated with environmental gradients, elevation and landscape resistance rather than geographic distance, supporting isolation by ...

Summer pruning for maintaining slender spindle bush type of peach trees grafted on vigorous rootstocks [PDF]
The slender spindle bush type system is commonly used for compact-sized trees, especially grafted on dwarfing rootstocks. It is difficult to apply this system to trees grafted on vigorous rootstocks by winter pruning.

Forest edges buffer effects of agricultural management on bee–plant interaction networks
Agricultural management effects: Organic and conventional crop margins host similar bee and plant species, but network structure differs: organic farms exhibit higher interaction diversity, conventional farms higher connectance. Role of forest edges: Native forest edges stabilize bee–plant networks by providing continuous floral resources and suitable ...

Influence of different pruning solutions in kernel production of a super high-density almond orchard [PDF]
The success of the super high density (SHD) system on olive production has been extended to almond orchards, where it is necessary to ensure adequate canopy dimensions for over-the-row harvesting machines.

The Effect of Traffic Congestion on Labour Investment Efficiency
ABSTRACT The study examines the effects of headquarters‐city traffic congestion on labour investment efficiency. The results indicate that firms headquartered in congested cities may engage in inefficient labour investment decisions. Further analysis indicates that the inefficiency is associated with both overinvestment and underinvestment in labour ...
